We have made several improvements to our already
proven reliability and energy efficiency. We have
upgraded our production facility to handle these new
People are often confused
when they look at spas. The advertising, as far as I
can tell, never really matches the reality of these
devices, until you come across our Haven Spas. We have
the proven track record with our appreciative Haven
Spa owners for over 15 years of praises and comments
on the reliability. Since reliability is what we are
all about, and we use only proven engineering. We have
no competition in the quality arena.
In Haven Spas, we are not motivated by cost cutting, we
actually use the laws of physics to the best possible
We use every modern part which improves water flow and
has been tested for longevity.
For instance in our plumbing we use
way over-sized intake manifolds on our jet pumps. We
feed dual 2 inch branch lines, rated for 235-250
gallons per minute (way over-sized for 150-180 GPM
pumps), into a full sized 2.5 inch manifold. This
enormous manifold feeds the water with the absolute
least restrictions. Then we allow a continuous
straight alignment of water flow into the front of the
pump impeller (the "fan" that drives the water).
The water goes in straight and this stops almost
all turbulence before the water interacts with the
Normal spas will have utterly
turbulent water coming in at off angles into the front
of the impeller. In order for good impeller
pressurization you need both momentum and water flow
directly into the impeller, not on any side angles.
The standards used in all other spas is limiting
designs such as having only a 1.5 to 2 inch 90 degree
or even a sweep directly on the intake with no
consideration about turbulence entering the impeller.
Straight line into the pumps is the best with way
over-sized intakes, so that is what we do.
Using “people”comparison, entering a door as a
representative example of this; it is similar to
having to force people walking backwards to go into a
doorway when they are heading away from the door or
going across the door sideways. At the last second you
force them to turn around when their momentum is in
chaotic directions. Momentum is a powerful force is it
based on the scientific principle of inertia. (A body
in motion tends to stay in motion until affected by
In our (spa pumps entrance) "doorways" entering the
pump, all the "people" (representing water molecules)
are facing the door and have momentum in the direction
straight into the door already to enter.
And the doorway is huge, too large for the job, to
insure absolutely the least possible restrictions.
It can’t be done any better than what we do it.
Given the space we are working with. (Unlike the other
spas, we make space for this in our spas.) That is
scientific fact. The full foam spas do not make space
for anything, but foam.
There is only momentum of water flow in Haven Spas in
a direction that is straight into the impeller. We
make is so the entire "run" from beginning to end of
water flow at the jets uses the scientific laws of
physics to the highest degree possible within the
plumbing system. The main water inlets are at the
bottom of the spa with the most natural “head” or
pressure of water with the least amount of
encapsulated air bubbles.
This photo below is from a standard spa site, showing
a bad, turbulence creating, angle on the intake of the
pumps. (and the typical crammed spa equipment
compartment) This is typical and seen on nearly ever
brand I have examined. As a hydraulic engineer,
you never do this to the suctions on a powerful spa
jet pump. This tells me they don't have any hydraulic
engineers or if they do they are really limited
people. Typically, in a full foam spas they have
to stuff the equipment in a small space making it
impossible for clean suction plumbing, and they never
seem consider that this is a bad idea to make such
sharp angles going into or out the pumps.
We are not showing our spas for
the sake of stopping competitors from their
continual copying of our designs. It takes a
lot of work to make the plumbing as large and
clean as possible. It takes planning to get
only smooth pipes and smooth transitions.
But here is a drawing, photo of
the way we make straight transitions into the pump
from the manifold. Notice the long straight pipe
entering the pump. According to the hydraulic
engineers I have chatted with you need at least
8.5 inches of straight pipe prior to the impeller
to get the turbulence under control. That is a 2
1/2 inch pipe or 63.5 MM inside diameter.
(The competition thinks they have
stolen our thermal closed design but what they don't
understand they cannot copy.)
We seem to be the only company with complete
understanding of hydraulic (electrical, structural,
composite, water quality filtering, ergonomics,
massage therapy, thermodynamics, and the laws of
physics) engineering when it comes to water
plumbing and all aspects of engineering in spas and
hot tubs. Because our spas are sold direct to
consumers, we are not restricted by a food chain that
would keep us from competing with our amazing
products. By not having distributors, or
dealers, we are able to be totally free to put the
absolute best engineered designs in our spas and
implement them fully. That is fact, which cannot
be overcome by others. The combination of non economic
restricted construction and selling direct to
consumers cannot be beaten, or so far nobody has.
The results in our spas is that we
get more than 30% (average 51% more) more water flow
from the same exact type of equipment as used in the
industry. Don't you really dislike the idea of wasting
this energy as well. If you purchase a 3 HP
pump, why would you not want to get 3HP of water flow
out of it. If a pump we use is rated at 19 PSI
(1.31 Bar) and 150 Gallons per minute (568 Liters Per
Minute), then we get 147 to 148 GPM. (556 LPM) We do
this by exceeding the standard rating on the pump by
our intake with as close to zero restrictions and our
exit or pressure side plumbing that allows only one
sweep and the jets to cause the needed back pressure.
Pumps run in what is known as their “sweet spot” and
it is a point where the maximum “power” is transferred
by having the back pressure match the power curve of
the jet pump. This means that you can have more water
volume listed, but if the back pressure is less than
10 PSI there is not much power being transferred to
the bathers back for therapy. (200 gallons per minute
at 5 PSI is nearly worthless, but it sounds good to
have 200 GPM in the brochure.)
I saw an advertisement with a "flow meter" showing 200
gallons per minute, but they have no mention of the
water pressure. Without that the 200GPM rating is
nearly meaningless. With 200 GPM and 5 PSI you have
way less therapy at the jets than 100 GPM and 19 PSI,
because the pressure to the nozzles is a necessary
ingredient in determine the actual felt therapy or
"power" being transferred from the pump to the
For this reason we list both the pressure and the GPM
or LPM flow as well.
According to ALL the hydraulic engineers I have
discussed this with, (and all of them are not in the
spa industry) the "worst thing to do to a centrifugal
pump is restrict the suctions." Period!
The best thing to do would be to put the pump directly
in the bottom of the spa with the full foot well for a
"suction" fitting. We do the next best thing and we
also exceed the safety rules this way.
One more very important scientific fact is that
sucking water from the top of the spa through a filter
causes more restriction on the suctions.
According to the pump manufacturers (which do not
recommend using filters on the suction of a jet pump)
you must have a way to keep the pump from cavitation
on high speed when the filters are clogged or it is a
horrible design. (Hint; The largest manufacturer
of spas uses only filters on their jet pumps).
We only do this when we use the MM and the WP pump as
the circulation pump, then we do some special valving
on the filter side to bypass the filters as much as
possible when that pump is on high.
When you take your water for your jet pumps ONLY from
the bottom of the spa, you are using all the natural
head pressure available so the water has pressure from
being at the bottom of a 200 to 500 gallon tank ( the
seating area is the "tank") with water.
You know that when you dive deep the pressure goes up
and your ears will start to hurt if you don't use ear
plugs. This is because the lower you go
the more pressure.
It is an extremely obvious engineering concept to use
all the natural pressure you can get if you want
to use less energy to create the most powerful jet
This is why sucking water from filters at the top of
the spa is ridiculous in order to achieve maximum
energy efficiency and "being green" or if you just
want to save money and have much longer life on the

if you are stupid." John Wayne
How the “pressure side” is designed.
We are the only spa manufacturer who considers the
best possible way to allow water to flow from the
pump's pressure side to the jets.
The ideal is the least restrictions possible and only
use the jets as the cause of any back pressure. The
way to achieve that is very linear logic and follows
basic and advanced hydraulic engineering.
Here are our design rules that we follow exactly:
1/ ZERO, 90 degree sharp turns allowed on any
main pump line. We use only ONE 50.8 MM (2 inches)
sweep with a radius of at least 76.2 MM (3 inches) on
any pump. If we use any turns to a diverted or TEE it
is way down on the plumbing tree where it has the
least dynamic hydraulic head loss (water flow
2/ No Diverters directly after the pump's pressure
outlet. Diverter valves can restrict the water flow
from "dynamic head loss" by up to 35% on high HP water
pumps. Analogy: You do not want to stuff 10LB of water
flow in a 5LB bag. Or don't put rocks in your car's
exhaust pipes then expect it to work properly.
3/ We eliminate turns, and TEE's in the direct flow to
the jet manifolds as much as possible. On our high end
spas we have only direct to jets plumbing with no
other parts in the way. We do not split water flow
using any form of unnecessary restrictions.
To do this requires careful design considerations and
we even adjust the manifold positions on the jets.
4/ The manifolds have different outputs of water
pressure depending on where the manifold outlet is. If
you understand this then you can position the right
manifold outlet to the correct jets for specific
pressure therapy considerations. For instance:
we put the highest known pressure outlets to the lower
human back, because that area can take much more
pressure and needs more pressure. The mid back
needs less (softer muscle tissue), so use the outlets
that naturally have less pressure on that area of the
body. Upper shoulders get the maximum pressure
remaining after the lower back jets.
5/ We allow for any "sonic" wave patterns that may
develop in the plumbing. We make sure all the
possible areas where any pulsating sound wave can
cause any back pressure in the opposite direction to
the water flow. Most spa designers don't even
understand this principle.
For example in a two cycle motor cycle engine they use
what is called "extractor" exhaust that uses sonic
waves produced at high RPM's of the engine to actually
pull the exhaust out and away from the engine. This is
because two cycle engines need help with exhaust
because they have no real exhaust valves. Extractor
pipes are recognizable by the fact that they are
tapered pipes, like a funnel, expanding, going wider
as it goes to the exit of the exhaust.
Then it has a sound "reflector" at the end that causes
the pulse of sound wave to reflect and feed back and
"extract" the exhaust with perfect timing to the
certain RPM of the engine which the engine has the
In spas we do not want any "reflectors" of any sound
waves to cause the water to have any back pressure at
all. No water waves or ripples going in the
opposite direction allowed. We do this by carefully
positioning and testing the manifolds to release any
back pressure at the ends of the run and we keep the
runs smooth and straight with slightly larger pipe at
5/ Use solid pipe on the pressure side as much as
possible. We only use smooth flex pipe or large solid
sweeps to make smooth transitions around a corner then
we go "straight" as much as is physically possible
inside a spa cabinet.
Straight, solid pipe has the least restrictions
possible. When water is in motion and has momentum in
a straight line, keep it going in the same direction
for a long as you can without turns until you reach
the manifolds (outlets to the jets). It is
like shooting an arrow in a stream line fashion. The
shortest path is a straight line, and the solid pipe
is the smoothest pipe there is. It also lasts longer
than any other pipe.
6/ When we make our cheapest basic models (which have
far better therapy that many of our competitors two
pumps spas), and we use a diverter valve concession.
In order to make a one pump spa that wins out
with therapy, we use a special designed plumbing
system with a diverter, called “Easy Flow Therapy
Control”. That valve is spaced a distance "down"
on the plumbing "tree". So that it does not affect the
output of the jet pump.
The worst thing competitor's spas do is to use the
diverter directly after the jet pump. We will
have several jets running "all the time" the pump is
on and then split the end run between two sets of 6 to
8 jets in a very even pressure distribution.
The way you know that a valve is installed correctly
is that you can turn it with one finger when the jet
pump is on high speed. (Try this with any other
spa!)That way you know the valve has the least amount
of restrictions and is used way below it's maximum
flow design. The numbers are 90 GPM, maximum, passing
through a valve rated for over 150 GPM with 12 feet of
dynamic head loss.
By reducing the “dynamic” part to 90 GPM at 15 PSI,
the dynamic head loss is less than 6-8 feet of head.
The valve outlasts any other spa using the same valve.
We, literally, destroy all the competition, in
comparison to water flow and jet pressure, when it
comes to jet pressure. We have full power and the most
useful horsepower to the water jets. We get the
maximum possible water flow and do not waste any flow
by unnecessary restrictions that are common in ALL the
competitors' spas. More pressure less wasted
energy and the pumps last about 2x as long. All
it takes is common ordinary everyday hydraulic
engineering to achieve this.
The competitors are not
concerned about any level of perfection because
consumers are so ignorant about spas.
7/ The end result is that the jet pumps run in their
"sweet spot". The "sweet spot" is where the
manufacturer of the pump recommends the pumps operate
in terms of water flow to the back pressure. All
centrifugal pumps require a proper back pressure to
make them run at the optimum "power" output. If
you drop the pressure and increase the water flow you
actually lose power.
Power or the actual therapy at the jets is measured by
the proper back pressure to give the maximum
intensity. We control the back pressure to
maintain proper power transference to the water jets.
The therapy jets are the back pressure and nothing
else in the plumbing line is allowed to cause
unnecessary back pressure.
8/ Gaps in plumbing connections. There is a
problem of turbulence when there are any extra
distance of "gap" between glue joints or fittings.
To insure this we do not use hand cut pipes unless
they are cut in a jig. Even the flex is cut on a
square saw. They are cut perfectly square so that any
joins are as tight as is possible.
Every gap causes some extreme dynamic hydraulic head
loss. It is like putting reduced size pipe or
restrictions in the plumbing. As the water passes the
gap it is swirled and swirling causes the water
molecules to be going in the wrong direction to the
If you don't know any of this, is "ignorance" really
Now you know some of the main reasons why our
equipment outlasts all of the competitors. We
run the equipment in the most smooth possible ways.
The pumps never pulsate. There is no way for them to
pulsate, because all possible ways for restrictions
and any sound waves gaps, and wasted turns are
We are the only company who does this. Our
reputation with our customers is the best. We have the
longest time between any repairs of any spa company on
earth and we have the longest warranty of now 7 years
on all the equipment and plumbing. This is because we
have the records of 10 years average, between any
needed costly repairs.
If everything is running smoothly, it just lasts much
longer. We are the experts at spa design and no other
company seems has the wherewithal or the business plan
to do this. They just do not know or they don't
care or they have no real understanding of spa
engineering. I think it is all of the above.

"Genius has its limitations stupidity does not" A
Summary of the gestalt of all this and the electrical
The next thing that seems to be a problem with spas is
using improper controls with undersized relays on
circuits to the components.
The solution is simple: Use the correct size of power
relays to any device and as in the case of Haven Spas
use over-sized contactors and relays to insure the
absolute longest life. Our relays are rated for over
100,000 actuations or “on-off” cycles. If you turn on
the pump 4 times a day you would have 100,000 / 4 or
25,000 days which is longer than a human life
expectancy for a person 30 years old who buys the spa
or 68 years + 30 = 98 years. Like I said we build in
In our American and European spas we use 30 amp relays
and contactors to drive our high horsepower pumps and
heaters. Relays are rated by horse power because
inductive motors use a lot of starting current. You do
not want to "starve" a motor while it is starting of
enough current to overcome the inertia and get the
motor up to speed as quickly as is possible. The more
resistance in the switches the longer it takes to
start because of voltage drops when you put too much
current on an underrated device or too small of a wire
size. Using “over kill” insures a very long life of
more than what is needed.
As the contact points of the switches age they start
to have some resistance. If they are way too
large to begin with and you are only using an average
of ½ of the power rating aging is not a problem.
We manufacture our own spa shells from sheets of the
finest acrylic from America. The proof is in the
old Haven Spas sitting our in the extreme weather for 15
years and having the same look as when they were new
with no cracks, blisters or blemishes. Our process
involves three layers of expensive vinyl ester
(vinyl-ester is like the strongest epoxy in strength).
Then we apply a neat layer of polyester resin and start
using hand rolled fiberglass. The bond from the vinyl
ester is so completely covered and bonded that the
polyester becomes both blocked from any moisture content
and cannot be separated except by extreme me means. Like
beating it to death with a huge hammer. The we apply a
second layer of polyester with a smaller content of
calcium to harden the shell and stop flexibility as much
as we can. The final layer is also tinted with a heat
absorbing tint so that the DAIT system works better than
any other insulation system on earth. We would
love to challenge anyone who thinks their shell is more
When we have nearly 35 years of knowledge, from seeing
the results in people's back yards, on how to make the
best shells, why would any company make
inferior shells and sell them as "the
best"? (Hint: greed, ignorance, or
both. People say I am blunt, but when you know the truth
about composites it is difficult to argue with me. )
We are the only manufacturer of spas also using an
infrared gas oven using NO electricity converted to
It has always amazed me that any company would use an
electric oven with 150 to 450 amps of 3 phase
electricity when electricity is dirty for the air, or
uses nuclear energy which we know is not safe.
Haven engineering consulted several gas heat engineering
firms in order to design the only infrared gas burner
heated oven used in any production spa manufacturing. We
built this oven from scratch and designed the electronic
control system to use these burners in zones. It
also heats the sheets faster and shortens the time to
heat and form. Not only is our shell manufacturing the most
energy efficient and cleanest for the environment
(the greenest!) it works better than electric
burners that have varying infrared color frequency
as they are heated and cooled. Electric
burners change rapidly over time and rapidly lose IR
frequency response. They need to be replaced
often, but are not replaced as needed because of time
Why would you
use coal to make heat, convert that heat into steam,
use the steam to rotate a turbine, transfer that
rotational energy to an alternator power generator,
then pass that electric current over thousands of
miles, then transform it down to 240 v and convert the
electricity back into heat. It is an
environmental stupidity in action to make spa
shells with electric heat. If there is no
natural gas or propane in your area, then you have
When you burn natural gas in a catalytic burner it
produces almost zero unburned hydrocarbons. It is the
cleanest energy we could ever find for this
purpose. It leaves as CO2 and water
vapor. Carbon Dioxide is needed by life on this
earth and is one of the best elements on earth.
This is not like your mothers gas stove! It uses
high intensity infrared heat energy that transmits
deep into the acrylic to quickly produce shells.
This is called thermo-forming or heat vacuum forming
also called thermal vacuum forming.
Then we apply multiple layers of proper
fiber--glassing resins to reinforce these shells for
the maximum longevity and beauty. We use
vinyl-ester first layer, then vinyl-ester second
layer,then vinyl ester third layer, then layers
of polyester resin made especially for acrylic spa
shells. All hand rolled and parts are hand
laid in areas of deep contours, like the filter
housing and the neck collar. This is the most
expensive to make shell on the planet and it is also,
oddly enough, the best known shell ever made for spas.
By the way; we use mold blocks to give us above water
neck and shoulder jets. Take a look to see how
many of the so called "high end" brands use mold
blocks. Mold blocks require three times the
labor to make shells, so we also support employing
people in our efforts to exceed any other spa brand in
quality and therapy.
We do this by selling only directly to consumers and
have no middle people. This is the highest end
quality spa made today by far, and we have the
scientific evidence to prove it in an court of law.
Some USA motors use over 80 amps
for a split second during the start of the motor on
high speed. This is why the running amps are
secondary to the actual inductive horsepower rating on
On our European models we use from 9.2 amp 2.5 actual
horse power to 12.4 Amps 4 HP, with super efficient
motors. We also use stainless steel motor shafts
to prevent rust. The motors are sealed and have
large fans to cool them to match the high standards of
CE certification. They also have "class F" insulation
on the motor windings. That is the highest temperature
rated (311 degrees F or 155 degrees C) winding
insulation there is.
These motors are "worthy" of respect and to be taken
care of properly. It is almost sacrilegious (sort of
like the Anti-Engineer of spa science) to destroy a
motor like this with improper pump size, poor
plumbing, and incorrect contact switches or incorrect
wire size to operate them. I find it
disrespectful to design in self-destruction on any
piece of equipment. It is also against
any form of environmental consciousness (ethics)
to just waste things by destroying them
and putting them in the trash when pumps used daily
have a life expectancy of 12 years nominally, if
and only when used properly.
I have looked at nearly ever spa made today on the
inside, and not one of them is designed to any level
of engineering standards to allow for full flow of the
jet pumps to the water jets. They simply don't know
how to do it or cannot do it because the design
is not integrated.
By running them with extremely efficient plumbing that
does not cause any extra drag on the water flow, the
pumps run cooler and they run very smooth. You
cannot hear any plumbing surges or restrictions in our
spas. They sound like music to the ears with continual
smooth water flow and no pulsations at all. The motors
start fast and run smooth. Isn't that what it is
all about? (Most spas sound like "trashing
machines" to me. Literally, the are beating the motors
to death. )
Combine that extraordinary plumbing with the extreme
electrical efficiency by doing the same thing
electrically with over-sized switches (relays and
contactors) and over-sized wires, so the pumps motors
are never "starving" for starting or running power. We
give the pumps and motors what they need to run with
the most power and efficiency without any of the
"normal" over taxing of any parts as found in
It takes special care in construction to do this.
It takes a special type of craftsmanship to make
a product this well. I call it ethical, conscious and
objective awareness manufacturing. It offers the
best respect to our customers to do this for them.
I really don't understand this industry tendency to
use absolute minimum sized switches and restrictions
on the plumbing and then expect failure as being
normal. (When you listen to people on the
forums, they often are sales people working in
traditional stores. The first thing the say about
"internet spas" is "Who is going to do the repairs
when they break." My answer is this. If
you design them correctly they will run for at least
10 years with no warranty problems. Why can't
they do that?
Why is that normal? Why is that acceptable?
If you save 5% on the cost of electrical parts, in
order to just get past the warranty and your yearly
sales are $14,000,000 dollars, then you have made an
extra profit of 700,000 dollars. Why is this good idea
at the cost of having your product fail much sooner
than necessary, normally just after the warranty is
over, and continue to ruin the already bad reputation
of spas in the USA.
Some of the early spa companies
when they were smaller, made good products. The
biggest problem with spas is money and wasteful ways
of marketing. We found that direct to consumers
is the ONLY way to have highest quality at an
We are not going to allow any reduction in quality on
our spas that we make. We want to have the continued
reputation in USA and Europe as we have in the USA of
the most durable and pleasurable spas ever made.
We already have the reputation of spas lasting for 16
years running on the original equipment and a warranty
rate of less than 2% over 5 years, in the USA, by
simply following normal engineering and design
principles that are available to anyone. With
the improvements we now have we expect 20 years of
life on equipment if you take care of the water
This is why we now offer a 6 year warranty on our
spas, parts and labor. We don't expect to spend money
on repairs, because we spend the money on making a
better (best made) product.
We don't want to be any part of "normal" , so we stand
alone on making spas that will endure and outperform
any other spas. I put up the "Spa Challenge"
many years ago and sent out notices and polite
requests for all spa companies to do a side by side
spa challenge in the mountains of Colorado. Sort
of a put up or shut up contest.
Long after we stopped this
challenge. because no other spa company
wanted to be humiliated, one guy contacted me from a
small factory, and he had no idea how to make a decent
spa, so I told him if he wants to sell his product, it
would be best to follow what all the other
manufacturers did and don't even respond, because they
know they would lose.
In every detail area of spa design we excel over any
competitor. Right down to the screws we use. Yes
we use screws and modern high tack adhesives to
assemble our cabinets, not staples. The frames
are 145x44 base and 94x44, vertices. The cabinet
has a structure that can withstand over 60,000 Lbs of
We have the data on energy efficiency in that our spas
use less energy to maintain the water quality and
temperature, and while the spas are open and running
we have the energy of the motors all going back into
the spa water as heat. We have the only thermally
sealed spa, using modern "space age" insulation
techniques, in the industry. The cabinet is actually
sealed like a door on a freezer with rubber seals.
We have the largest intake manifolds on our spa pumps
and we avoid all the turbulence on the intake by how
we design in a clean entry into the pump wet end.
We use the cleanest and most robust plumbing to the
We get over 97% of the, rated, output of a water pump
to the jets. If the pump is rated for 150 GPM/19 PSI
at zero head loss (with no pipe turns on level
plane). We get 147 GPM at 19 PSI to the water
jets. This is because we exceed and oversize all of
the plumbing and we get more water flow than any
"normal" spa using the same pumps. By using the almost
perfect intakes we get more water flow at zero head to
start with. There is almost no resistance to the
intake. We start with the best natural head and we
don't screw it up by "stupid plumbing" ideas.
By testing we have determined that the minimum
pressure needed to get really great therapy is 12 to15
PSI with a 7.94 to 9.53 MM orifice jet nozzle.
Then we optimize our "hot seats" (the main captains
chair therapy seat in our highest end models) to have
19 PSI to these extra large size jets. We never
use the cheap bullet (Euro
Jets or Cluster jets) jets on the backs of the
human body. Except for specialized therapy along
with large jets.
Now, we also have the best idea when it comes to
thermal expansion and contraction on all the major
parts inside the cabinet. The water in the seating
area is used as a “heat sink” and it regulates the
inside cabinet temperature to withing only a few
degrees. (Full foamed spas and other poor
designs have drastic temperature changes on the
equipment and all over the plumbing area with
different and rapid rises and cooling: way too much
thermal expansion and contraction to last.) The huge
surface area of the spa vessel is a huge heat sink
that draws in all the motor heat and eliminates the
need for venting in 90% of the world.
In very hot summer areas, like Phoenix AZ or on Bali
Indonesia we put vents with temperature controlled
fans to cool the cabinet as part of the DAIT system.
Our spas are actually running the motors much cooler
than in any spa with full foam and or a small
equipment area that relies on convection cooling and
Outside convection venting is a waste of energy, when
you can simply put the heat of the motors into the spa
water and help to reduce the use of the electric
Outside venting also causes freeze damage to spas when
the power is off or the equipment has any problems
that stop it from running. Since most spas have
problems, the freeze damage issue is exacerbated by
venting and weak equipment that has a known failure
rate. Freezing air enters the cabinet and
freezes the water in the equipment causing very
In Haven Spas the cabinet is sealed shut, so that NO
cold air can enter to freeze anything and the spa
vessel acts as a huge “hot water bottle” to stop the
air from getting cold for weeks at below zero
The back of the shell, the vessel where the seats are
is coated with a heat absorbing coating. We do this to
make the radiant infrared pump heat absorb quickly and
directly into the spa water.
Even in Colorado mountains we can outlast any other
spa for freeze down time so the urgency to get the spa
repaired is eliminated and you have time for remedies
that are far less expensive than $1000 to $3000 in
repair damage. (Digging out a full foam spa is
Why do people buy other spas?
To keep the trash dump busy, maybe. We
often take other brands to the dump in or service
work. Somebody needs to do that.
Ignorance? Not researching the market? Technically
We can't really help the "technically challenged". If
you don't understand basic science, (common sense)
then you need to find someone who does and have them
read this for you. Otherwise, you will miss out and
lose the opportunity to own a real spa that is
reliable and easy to own with the best therapy.
Ignorance is not bliss when your full foam spa freezes
and normally you wind you taking it to the trash dump,
because the repairs are more costly than any 5 year
old spa is worth, except for Haven Spas which have the
highest resale value of any spa made today and they
don’t freeze unless you let them set for weeks with no
There is no other spa with this level of design and
Years ago I put up the "put up or shut up" spa challenge.
We do not have any competition unless you are not
educated on spa design and have not the understanding
necessary to make a good choice.
Therapy in Haven Spas
From many years of research into the
design of water jet therapy patterns, we have come up
with what really works according to how the human body
is made and what types of jets actually give real
therapy to the muscle groups in the human body.
We have found the simple formula
that large muscles like large jets and they like broad
pressure and they like rotating jets with a feeling of
pulsation. This is why we
insist on full size jets in the back of the seats and
in patterns following the way the muscle tension shows
in human bodies.
The mid-back has much more
sensitive muscles and so we reduce the power of these
jets to give proper therapy according to thousands of
customer’s feed back.
When ever you see tiny bullet jets
also called “Euro Jets”, “Cluster Jets” or “Ozone
Cluster Jets” in the back of the seats you are not
getting proper therapy. These are like having a
“pencil” poking you in the back and you cannot set
close to them without getting red spots.
There was a test done in the mid
1990’s on these bullet jets with a full size pump on a
diverter forcing the power into 14 bullet jets. It was
performed on elderly people and each person had black
and blue bruises from this “therapy”. It is
literally ridiculous to do this to people and give in
fancy names, like "superintelligentassage" and print a
whole page on this "bla bla assage" therapy, when the
jets are the cheapest jets made today and sold as some
sort of “good” thing to shoppers who know nothing
If you want therapy you need
therapy jets. PERIOD! You don’t want pencils
poking you in the back and you want large rotational
jets producing real massage.
Haven Spas beat all competition
when it comes to therapy. In the USA the same
models made for the USA market have never lost a
comparative wet test against any other spa. This
is a fact and after 14 years of having this therapy,
the customers don’t even want any upgrades because
they don’t need them. We have always exceeded
any other spa when it comes to real therapy.
Our captains seat in our main line
of spas, Vista on up, spas is set up with the
largest rotating and best known therapy jets you can
buy. The also cost about 8 times what
these cheap bullet jets you see on
the poorly designed spas. When you hear about
"100's of jets" and idiotic sales nonsense like that
you can be assured they are cheap bullet jets that
have no pulsing massage action at all, but are just
nozzles that spray like a garden nozzle and they are
not very therapeutic at all, like pencils poking you
on your back.
Haven Spas uses high water flow
jets that perform real massage. They are placed in
patterns that are known to work on the human body and
they don’t really require any sales presentation at
all after you try them, then go try the competition.
There is no comparison. The therapy in Haven Spas is
literally from 2 times on our cheapest models to 5
times the therapy of any other spa. Period. We
use the best jets and we also have the Power jet in
the lower back as an option. If you have any
lower back pain, it will quickly go away with the
The power jet has a 25.4 MM or 1
inch nozzle and there is
normally a 14 jet Power foot massage
on the other side of this jet system as the
complimentary foot therapy. The
upgrade has both jets running on a
separate jet pump.
The therapy in Haven Spas will
continue without fail for years and years.
We make this power to the jets
without any self destructive equipment
or restricted plumbing. It is
smooth and powerful and also fully
When you add the Turbo massage to
the water jets, we destroy the competition
completely. They don’t seem to
even know what turbo air massage on
water jets is. It allows more
pressure and an even broader
distribution of water to the
affected body muscles. It is amazing
and will take away your stress,
muscle tension even faster.
10 minutes in our “captains chair”
therapy seat, is better than one hour in a spa with
cheap jets. You will never achieve this level of
therapy in any other spa made today.
And all of the jets can be adjusted
in an almost infinite level of changing
intensity, from very light massage,
on those days, and when you are
really sore and need a real deep
massage you can have that as well.
We don’t play the game of jet
numbers over the quality of the therapy. On
of our full size jets has the water
output of 4 to5 bullet jets AND it has
real massage. Don’t get fooled
by jet numbers vs full and
powerful jet massage using REAL jets
instead of "toy" jets.
The jet patterns are tried and
true. We know they work because of the
thousands of people who own our spas
in the USA and they rave about the
therapy. After 14 years of ownership
and the spas still perform as they
did when they were new, we can say
without any doubts we have the best spas that have
ever been made to date.
If you don't
care about therapy, then you don't need a Haven
Spa. If you don't care about energy efficiency
nor longevity, then you don't need a Haven Spa. If you
don't care about the environment and throwing away a
broken spa in the land fill, you don't want a Haven
Spa. If you like spending extra money on broken
parts, you don't want a Haven Spa. If you don't like
nice clean fresh smelling water in your spa that is
properly filtered, you don't need a Haven Spa.
I can't help
myself. After all these many years of hearing stories
from people who call me and on other brands of junk
spas, with many expensive repairs and high electric
bills and weak jets, because when they bought they had
no idea about hot tubs. They thought: "a hot tub
is a hot tub and the salesman was nice, so we just
stress in a product that is supposed to reduce stress.
We also use very logical design on the filtering of our
spas to get the maximum filtering with the least
possible restrictions on the suction side of our
On standard models, we use a special valve that is
designed to close and force all the water through out
twin 50's filters, 100 square feet total filter surface,
and these are REAL filters not screens as used on poorly
When the jet pump goes on high the total water available
is 335 Gallons per minute on a 150 to 180 GPM spa pump.
Again "over kill".
When we use a high volume specialized circulation pump,
we will put the entire flow of that pump through the
filter as well.
We follow the ANSI/UL CE, for safety and get the
best filtering at the same time.
