The DAIT insulation system is the best of in the Thermally Closed
style of insulation. It is the most technologically
advanced and logical design for spas. It is also the
most energy efficient design (We have proposed the Spa Challenge for years with
no takers). The original concept of the Thermally
Closed design was developed over 20 years ago by a large
corporation* with real engineers, making it the only
engineered type of spa insulation in use.
As the spa equipment developed, the size of the
motors started to cause problems with the original design.
There was too much heat trapped inside these early
cabinets as modern pumps were installed, and it developed
into a problem (Because the engineering of the insulation as
not keeping track with the new equipment).
We took over where they left off because it is the best idea
for spa insulation today. Haven Spas advancement of
this thermally closed design (along with other innovations)
has made us about 20 years ahead of any other company in
quiet powerful, long lasting energy efficient spas. We
make the best engineered therapy spas on earth today.
That is not a marketing statement. That is a statement from
over 20 years of in the field results and having our spas
outlast all other brands.
When we started to do our research and development on this
concept of automatic adjustable insulation, more in winter
and less in summer we had a few spas that we tested. The
problem at that time was if we set up a spa for the coldest
part of winter, it would not work in summer, but it had phenomenal
energy efficiency in the dead of winter, when
spas are mostly used (at least in Colorado). In our
test spas the insulation had to be removed in order to stop
the water in the spa vessel from getting too hot in spring
through fall. So, as we went along we discovered that
at certain temperatures outside, you start changing the
insulation by removing it from the cabinet walls.
This was not practical for a spas that is sold to the
general public. I can't imagine an older lady with a
screw gun opening up the spa to adjust her insulation four
of five times a year. So, we took and designed full
winter insulation then automatically reduced the
effectiveness of it in warm days to keep the spa water
"normal" temperatures and even allow for cool
The standard thermally closed (non DAIT) spas are more
energy efficient than the standard full foam, have full
access to all the equipment, and run extremely quiet and
don't overheat in summer unless the filter cycles are set
too long or at the wrong time of day. This had been
our standard for 14 years, but we are now finally able to
offer the DAIT insulation system in all its glory.
With the DAIT system, Dynamic Automatic Insulation
Technology TM, we
automatically adjust the effective insulation by moving air
in and through the cabinet and creating an effective
reduction in heat retention in summer.
The range of effective
insulation varies from R-87 in the Paramount and SC
models in full winter to R-11 or less in summer, but it also
adjusts in summer for night temperatures and increases
insulation then. It involves using thermal sensors and
a control system (proprietary) to make all the adjustments.
It comes in two versions the "Level 2" is much simpler
and only uses internal sensors and standard logic, used in
warm climates. The "Level 4" has multiple internal sensors
and external sensing of the thermal conditions inside and
outside of the cabinet. The "Level 4" has even more
controls on the cabinet and allows us to run a cool spa in
summer if you want. Level 4 has four layers of
specifically engineered insulation. Since the DAIT
system is primary to the total function of the spa, it is
composed of industrial rated electrical and electronic
parts. These parts are rated for a minimum of 100,000
actuation's at full power rating or more. Since we run
these devices at 13% of full power, we expect them to
outlast the spa.
The advantages for this are numerous in the effective use of
the pump heat, without causing "hot spots" inside the
cabinet. If you look at a standard full foam spa, the
pumps are placed in a little box in the front of the spa.
When the pumps run that box becomes a hot box
particularly in summer, giving the full foam spas more
overheat problems than in our standard thermally closed
Pump overheat in these little boxes in fully foamed in spas
in these, 30 years behind, out of date designs is what
causes premature failures on the motors. Heat is
killer on spa motors. In every spa I have
examined by the competition, they do not seem to care about
their motors. I have this thing, called engineering
background, and I also read all the specifications and
parameters needed to keep motors lasting much longer, as
long as they ever can last. Some of our older spas are still
running after 16 years on the same motors.
In our standard thermally closed DAIT design the heat is
spread out in a much larger enclosure and that heat is
rapidly dissipated into the spa water, not one BTU is
wasted. Plus we use the highest quality spa pump
motors. This is a symbiotic relationship between the
spa vessel and the pumps. The only time the jet pumps
produce extra heat is when the cover is off and the spa is
losing heat "like crazy" out the top of the spa. That
is the time when the thermally closed is very energy
efficient and the heater use is greatly limited by the pump
heat going directly into the water. If you extract the
normally wasted motor heat and make that enter the water
while the cover is off, the electric 6,000 watt heater will
not operate for a much longer "OFF" time, even with
very cold weather. Keeping the water warm with the
least amount of heater use is the ideal concept that we have
achieved and no other brand of spa has this.
With the DAIT we have far superior insulation and we have
controls over the possible build up of heat in the area
around the pumps, so our pumps never run in ambient average
air above the temperatures specified by the motor companies,
thus fully extending the life of the motors. (Other
brands of spas attempts of capturing the heat and closing
the cabinet does result in pump overheat and shortening the
life of the motors. It appears that they have never read any
books on thermodynamics.)
In a typical full foam spa the ambient air is almost
always too hot in a short time after the motors start,
because the equipment box is too small to begin with.
In summer it leads to thermal overheat and the thermal
safety switches in motors shut off the motors until they
cool back down. By then the motor has already been
harmed. Running any motor too hot for even short periods of
time is like a disease being inflicted on these expensive
parts and who ultimately pays for that poor engineering?
(Hint: Spa owners do) Some spa companies are wasting even
more heat, by putting a vent on the back of the motor and
blowing the heat directly out side. (I can't tell you
how ignorant that sounds to me.)
With the DAIT the air entering the cabinet is made to pass
into the motor frame first, then after the air is heated by
the motor frame, it is sent out into the cabinet for heat
absorption into the spa water, through the vessel wall and
plumbing pipes. If it is summer, the heat is not
allowed to build up and it is expelled outside the cabinet,
so the water temperature will not rise but a degree or two
above the set point. This is also a lot safer than
The improvements in this DAIT
system are many in function, but the synopsis is as
- DAIT equipped spas have the highest
effective insulation of any spa ever made to date in
winter. There are 7 layers of effective air barrier foil
and foam insulation in these spas. The 2016 SC and
SE spas have 10 air/insulation layers.
- DAIT allows an automatic reduction in the effective
insulation as the thermal conditions warrant.
(DAIT 4 has multiple levels based upon
interior and exterior thermal conditions and what
equipment is running.)
- DAIT allows for control over the ambient air around
the motors affecting an increase in the motor longevity
by keeping the frame of the motor cooler than any
portable spa in current production. It moves the
heat away from the motors.
- DAIT allows a decrease in the winter electric
consumption that rivals summer use energy consumption,
while the spa is not in use.
- DAIT gives the spas an increase in the heat transfer
into the spa water in winter and less or very little in
- DAIT soundproofs the cabinet even more because of the
additional layers and air chambers added to the walls of
- DAIT allows even better use of the warm air into the
blower than was ever achieved before and the use of
higher horsepower air injection for more air features
than have ever been available with low energy
- DAIT allows the warm air in front to be brought
to the rear of the spa cabinet. Thus, equalizing the
heat barrier around the seating vessel.
