So what are the Best, Spas, Hot Tubs in the World?  And how can we call them the best hot tubs in the world?  Here's and article on the evolution of hot tubs to the level of making them products we can be truly satisfied with.  We follow severe ethics and educational approach in terms of having education for our custoers, never implying anything. Just facts and showing exactly what we are talking about.  Every concept used in the best hot tubs, spas, in the world is proven by science, engineering and empirical testing in the field of spa customers over 40 years of research.  That is why we can say we have The BEST HOT TUBS SPAS in the world. No other spa manufacturer can make that claim. For one thing they don't have any real knowledge or experience to back anything they do.

Most spa companies expect the spas to fail and need service. That is why spa service technicians are in serous demand across the country.   One of the highest paid service people in the world simply repair spas.  Maybe that is good for the spa repair people.  My son has his own spa repair business for nearly 18 years, and he only has to work part time to make a good living, and because of his reputation, he is in strong demand, has to turn away customers.

He told me this; "You do not need to make your spas so good.  They are way better than anything on earth, and I never get to fix them until they are very old.  It is stupid to make them that good, because you could make a lot more money by cutting the cost to make them."  He actually cares about me and wants me to make more money. 

I have an ethical "problem" in that I cannot sell anything that is not superior to all the rest, and I have some 50 years, now of engineering background to back that up with.  "If you want oats that have already been through the bull, we don't have them. We only offer fresh oats."

It is called the theory of relativity.  Since our spas have the history of the least cost to own on the planet, have the lowest electric bills every recorded, and last the longest without repairs, the theory of relativity is on our side.  When you compare everything we do inside our spas to make them superior in every possible way according to science and engineering, you just get the best possible product.  It is impossible for me to have anything less, because I am an engineer.  And our newest models are even made to higher standards in Holland. 

• Shell structure.  Acrylic backed with a vinyl ester resin bonding agent, (Rememer these are the Best Spas in the world)  and hand rolled fiberglass for a strong shell.  We use 5 layer method with three vinyl ester layers and two polyester for the strongest shell, absolutely the best, currently in production.  This is well known as the best shell structure. Most shells using other materials (or the same materials not properly laminated) are still experimental  or have a known failure rate of surface cracks and leaks.   If you are going to experiment with something on a consumer, it certainly should not be the spa shell!  (unfortunately this is the most expensive part, so most use inferior methods and/or materials.)  Use fiberglass, with a layered Vinyl Ester bonding agent behind acrylic.   (Don't buy a thin cheap single piece Acrylic/ABS shell stuffed with structural foam!)   If you want cheap, then don't pay high prices for it.
  
• The cabinet is fully engineered and structurally framed in 94x44 MM (3.70" x 1.73") lumber, top rail, bottoms frames are 145x44MM (5.70" x 1.73") and sides all structural framing.  We don't use plywood on the bottom.  The pumps are rubber mounted to the solid wood frames to kill sound and hold them solid.  The more mass under the pumps the quieter they run. We have a lot of sound deadening engineering use in Haven Spas.  This is stronger than any other form of hot tub manufacturing. According to my engineering reference a  94x44 has a vertical strength of  about 1500 LB per square inch or 1.5 x 3 x 1500 = 6750 PSI.  You can put a 50,000 truck on top of our spas.  So, don't tell me about cheap steel frames that fall apart or cheap ABS frames that have no value at all, steel  with rust or hollow plastic that is untested over time. We have 40 years of testing on wood frames and know how to use them. Wood is found on the oldest of spas (and in 563 year old buildings in Europe). And our lumber comes from forests that have been properly cultivated for over 1000 years in Norway.  There is a lot of human garbage about wood, from people who cannot afford to use wooden frames. There are buildings in Holland from 1465 (that is the years they were made) still standing and very strong.  So, please tell me what is better?  I have looked at every possible material to make spa frames from, including fiberglass, plastics, steel, and wood composites, and still wooden frames come out on top.  ALL of the oldest spas still working after 40 years have wooden frames.  
  
• The Pumps in the best spas in the world,  are all  a new, high energy efficient, Industrial level of 90 frame EMG's from Europe (Italy) motors with class F (310 deg F) insulation and with dual cooling fans and Stainless steel motor shafts.   These shafts do not rust as found in USA motors. These are the most modern of all motors and the highest quality, high efficiency, made for spas.  There is nothing better.  The operating air temperature is 50 degrees C or 122 degrees F. ambient air.  The armature has an extremely tight distance from the field coils to transfer magnetic power much better.  The winding coils are all larger wire, and the bearing and starting circuit is more along the commercial size, bigger.  It basically is an industrial size high energy efficiency motor instead of a 48 frame consumer grade motor.  The HP range is from 1.5 HP to 4 HP.  (We don't need 5 and 6 hp because they way we design plumbing for maximum power from the pumps to the jets.)
  
• The maximum horsepower we need is 4, because of the extremely clean large over-kill plumbing.  We use the cleanest, smoothest, practical,  plumbing available on any spa today.  It has fewer turns and larger pipe than most any of the standard spas "out there".  We engineer the plumbing to a much higher degree than anybody I know of.  There are NO sonic reflective problems in our plumbing. No backward sound waves destroying water flow.  We follow standard hydraulic design principles and make almost no concessions except over kill. You will never see a standard 90 deg. PVC fitting in our spas jet pumps. "Dynamic head loss" is at an absolute minimum. Haven/ Silver Spas run SMOOTH. They are music to my ears to listen to them run so SMOOTH and quiet.  No cavitation as found in nearly every other spa.  This is why our pumps last way longer than in any other spa.
  
• Much of our plumbing is made of solid PVC pipe and modern high density vinyl mass flex pipe.  In the high end models, we use more of it.  It has better water flow characteristics and a much longer life expectancy than old flex pipe on a pressure line.   This gives water a clean smooth and larger pipe.  In the engineering design reference manuals it states that solid PVC pipe and smooth polished stainless steel have the least resistance to water flow, or the most water can go through them without restriction.  Smooth inside pipe is the best. (a child's arteries and veins are like this; smooth and without tight bends)  It is best to make turns as sweeps, and to use smooth wall pipe.  Our flex has few ridges and is very smooth as well.  Old flex pipe has washboard ridges on it, causing water turbulence, and we try not to use that on our super high flow pumps.  Our pumps, on the best spas in the world,  use a 2.5 inch suction inlet manifold pipe and a 2 to 2.38 inch pressure pipe to the manifold. And we avoid "gaps" in the joints as much as possible.  The pipe is cut square on power-saws.
  
• We have the best  insulation design available today.  It is the only truly engineered and fully tested insulation.  The original design was done by a team of engineers from a huge corporation with deep pockets. These were actual thermodynamic engineers.  We have a third party testing with constant monitoring of every spa we sold in Europe.  Each spa has an energy meter that is sending data to a MQTT site and collects all the data on every spa we sell there.  It has been tested in extreme cold, to full summer with out problems.   With this system we extract all the energy used in the pumps, both mechanical and heat.   I don't like to waste money on electricity being sent out into the yard.  Much better to have the heat pass into the water first.  Read about the DAIT system and Download a pdf brochure.   If you like burning money then buy a different brand of spa.    Take a $20 dollar bill and just burn it once a week to get the same effect.  
• The digital electronics control system we use is better than anything I have found.  Reliability is paramount.  So, we are waiting to use Wifi, and other ideas until they stop screwing up.  We use a high end custom made control boxes with metal enclosures, and electronics with 30 Ampere and 40 Ampere sealed relays and 30 and  40 AMP to 50 AMP  contactor, relays on the high watt heaters.  Sealing the relays eliminates the air and oxygen to burn the points.  It also keeps the moisture out of the relay.  The circuit boards are designed to take up to 155 degrees operating temperature.  The spa will never achieve that temperature in a hundred years (unless we get hit by an asteroid).  We use air control methods to separate the control box from the heat of the pumps.  We have a total control over the thermodynamics of the best spas in the world,  Haven Spas. The control box is metal, instead of plastic.  Steel and aluminum manufacturing costs more but is much safer in the event of a short or arc in the control box.  It will not escape the metal enclosure. I have seen my share of spas that caught on fire and control box fires will not happen in Haven Spas. (Google "hot tub fire" and look at the photos. It is always the plastic melted control box that caught fire.)  And under our long testing of the inside conditions of our spas, we average 19% relative humidity. That means our controls are kept VERY dry, like Sahara desert dry.  Moisture is deadly on any connection in a control box.  You would NEVER want to own a regular spa near the ocean.  They are extreme fire hazards.
  
• We eliminate all of the dangerous loose filter lids.  They are dangerous and the first thing that people break.  I had a woman break her knee bone on a spa with a loose filter lid on an Older Coleman spa and I was showing it too her. This is how I know.    A loose filter lid is a bad thing!  It it the first thing your friends will lean on when they get in.  When they lean on it, it slips out and bangs their elbows, arms, and sometimes faces onto the hard shell.  I remember a fellow who came into the store I used to work at.  The lid had a lightening like tree crack that spread out from the center of the pressure point where it snapped.  It also had a blood stain on it.  He told me, and this is the exact quote: "They had to pull it off my ass."  OUCH!!  His skin tissue was caught in the lid when it cracked.  That store made a lot of money on replacement filter lids.  On all of the Haven models you can sit on top of our filter area with not problems because it is part of the acrylic and fiberglass structured shell. Other filter designs are just plain STUPID. You don't want to be stupid do you? Did I tell you that my friends all say "Jim,  you are too blunt and honest."
  
• All of our spas follow the ANSI/NSPI ASTM, UL and ETL, CE and TUV for safety.  We actually go way beyond the minimums.  For instance, most of our suction fittings are rated for 258 gallons per  minute and we use two on each second pump, as well as on the filter side we have way over kill for a safety reason.  The velocity of water per square inch is much less on the suctions if you use too large surface area of a fitting.  It costs more, but it will save lives, because nobody will be held by one of them, and hair is never drawn and held near the fittings.  I am a parent (grandparent now) and I feel that the ANSI standard is lacking and was written partially by stupid greedy people (I am not kidding.).  Our control system is modern with redundant safety shut-off's.  It will never have the pump stuck in the on position.    ( Never buy a modern spa with old fashioned air button controls that do not have safety shutdown timers on them. Click here to read control article)  The controls have automatic clean-out  on the second pump and blower at the start of the filter cycles to insure no yukky, stale, bacteria laden water in the plumbing.  If that water isn't purged daily it gets stale. Some really stupid spas, if you don't run the jet pumps every day will have bacterial laden water in the jet pump plumbing.  Our run those pumps and the blower every day to clean out this deadly water. So, do you want the lowest cost to own spa in the world, the best spas in the world?  Or do you really want to burn 20 bucks ever week if you own other crap spas?  It is up to you to make this decision and to find out what the heck I am talking about. 
  

• The ergonomics of the design incorporates flat areas to place cups and drinks.  As a spa lover, I find that you must have water or you will get dehydrated and feel tired if you don't drink water or Gator aid or juice or some drink to re-hydrate yourself..   Most Haven spas have a really nice area above the filter to put a tray and this makes a great serving area.  Rounded tops on the acrylic are antique and come from the really old days of spas, the same as filter lids.  The top area on Haven and Silver Spas (the Holland name of our spas) is nice to sit up on out of the water, since it is flat, it does not press into your bottom. If you wet test any spa sit up on the upper lip and tell me how comfortable it is.  I can't sit up on a rounded spa lip for more than a few seconds without pain. It will "pressure point your rear".  All of the convolutions on most spas are like wearing high heel shoes when you need to be wearing sneakers.  They are for design, not functional for relaxing.   (Women who prefer pain and suffering for the sake of design, are NOT our customers.)
• The seats in our spas were designed for COMFORT.  There is a reason for these seats.  We put at minimum 20 people in each seat of the mold before the first spa was ever made. That means that people of different body types are all FULLY comfortable in our spas. And we don't put that crap on the floor where people trip and hurt themselves.  No mounds in the floor and you can MOVE around easily.  It is the most stupid thing to put crap on the floor of a spa and try to walk to the next seat.  OPEN LARGE footwells are required on the best spas in the world.  Ease of use, safety (not putting trip zones in the footwells) and easy to move about without getting hurt.
  
• All of the main jets are adjustable, the inserts are removable by the owners, and you can put in different jets in the same jet body without tools.  This makes our spa the most  have the most customization for the spa owners.   The jet pressure is adjustable both up and down, by several controls.
• We put in hand rails in our spas.  Most spa companies are eliminating them even though the ANSI says you need them for safety.  Only on the smallest spas do we not have them.  Hand rails by definition are round and you can wrap your fingers around them. The hand grips, molded into the shell on some spas, are not hand rails. When you are moving about in the spa you want to have something to help you to move, especially as you get older, you need more stability.
  
• Since we have a warm air chamber in our spas, we can have a nice, very quiet,  air blower system and full turbo massage.  This turbo massage makes the jets stream much larger and give a great therapy effect.  It is similar to having a third speed on the water pumps.  All of our two or three pump spas have two speeds on each pump.  (Most spas will have the first pump at 2 speeds and cut costs on the second or third pump by making it one speed.)  It is only on our 4 pump spa that we have a 4th pump one speed but our new controls will have two speed on four pumps. This is about to change as we are developing and up to five pump control box with 40 Ampere Relays.  Haven spas with the optional air injection, have the air injectors placed in the most effective positions and we use the 9 Hole air jets on many models that act like 9 individual air jets in one spot.  This option is $2000 now.   This causes the air to burst out and give a great pulsating massage.  We are the only spa company to take full advantage of the turbo blower system, without the extra energy cost of blowers that draw in cold air.  The blower uses the heat from the jet pumps to maintain warm air into the spa water. On the Super Custom Magnum spas we use two air pumps at 2 HP.  This is "killer massage" killing all muscle tension.
  
• All of the Haven Spas are designed to be easily repaired.  That sounds simple and you would think that all spas would do this, (modern cars don't do this) but it costs more to install the pumps in different places and individually bolt them down, rather than stick them all on a skid and drop them in for less expensive factory production.  All of the side panels are fully removable to get to the components.  This is the best for service.  Saves you a lot of labor charges on out of warranty repairs.  All of the components plug in, unbolt, unscrew to be repaired and most of the water joints can be repaired instead of replacing the parts.  And NO foam on the shell to interfere with any jet repairs.  You save about $500 per repair just because of that, and you won't have to worry about any repairs for about 15 years on average. Most spas are in the trash dump in 15 years. Our spas have an easy 30 years of life in them and they never go out of style, because we are 30 years ahead of other spas in ergonomics, comfort, usability and therapy.  We have never lost a comparison wet test and I know this from calling back every person who has ever tried our spas, or owned one.
  
• Quietest spas: With all the refinements in design we have the quietest spas with full filtering and full powerful therapy you can get. These are the best spas in the world for sure.  If your spa is outside your bedroom you might hear, (if you are very young and have powerful hearing) a hum when it comes on to filter or heat: super quiet.  While the spas are on high speed, you hear water, not loud equipment sounds. The sound of a Haven Spa on full is "music to my ears". As an engineer I hear other spas and they sound like they are on self destruct mode...because they are.  As my father would say; "They sound like thrashing machines."   I can't even stand to listen to them, because I know they are destroying their own equipment with the constant vibration and ridiculous plumbing causing destructive wave back in the plumbing.  The water hits a wall or 90deg or gap in the pipes and it causes it to go in the backward direction.
  
• The filters can't be any easier to access on Haven Spas, the best spas in the world.  Programming can't be any easier.  Most models take 30 seconds to program the filter times and if you don't want to program it, that is fine.  It will function automatically.  It is important to be able to adjust the filter duration to match the use of the spa, so we make that available.  If a spa needs more filtering, we have that, less we have that.  If you are stuck with a tiny circ pump that is inadequate to begin with, you can't add additional filter times, only chemicals. You will notice that the debris goes into the filter.  (On the "number one selling  spas" it goes on the wall or on the floor of the spa.)
  
• On our upgraded cover we feature a much higher level of safety for children with 8 locking tie-downs.   This makes it twice as hard for a toddler to gain access to the spa.  It also helps a great deal with high winds of up to 80 to 90 mph gusts.   You have to use a key to open them for safety around children.
  
• Our Haven Wood steps or composite are super strong as well.  We use 52 deck screws in the construction to insure that it never collapses under normal loads , even two or three people standing on it. (now priced at $650, but they are very nice) We offer several of the composite steps as well. Composite siding and steps are much more popular these days.
  
• Our complete set of supplies is huge and is not a start up kit.  I don't believe in playing that game with customers.  Why not supply the spa with all the necessary chemicals?  If you want a starter kit, we have them.   I think we did one in the last 20 years.  We don't stock them.
• Our Water Treatment Systems:  we offer several water treatment systems.  We have ozone, with constant controlled separate cold air injection, normal ozone, and we have a hydroxyl system used with ions and ozone that is as chemical free as you can get.  We even have auto drain and auto fill spa systems available.  You press a button to drain (and it asks "Are you sure") and a button to fill, and it automatically fills to the right level then starts the control system.  This, of course requires water inlet plumbing and drain system plumbing.
  
• WiFi:  Our newest Control system is ONLY wifi for settings and has buttons by the seats for running lights, jets, air pumps and automatically opens and closes the air valves.
