Video Presentation View a brief explanation of Heat Siphon's pool heat pump history in the industry.

HEAT SIPHON WILL GIVE YOU DAILY SAVINGS FOR MANY YEARS, NO WORRIES, QUIET AND SIMPLE TO OPERATE AND ITS ENVIRONMENTALLY FRIENDLY.

SIX BEST Reasons to Own a HEAT SIPHON Pool Heat Pump:

Heat Siphon units are BUILT TO LAST.
Highest COP in the industry. The most efficient Heat Pump available.
a) The 100% TITANIUM, ELECTRICALLY ISOLATED, HEAT EXCHANGER is guaranteed corrosion free for the lifetime of your heat pump.
b) PVC CABINET, corrosion proof, won't crack, built to stand the most harsh weather conditions.
c) STAINLESS STEEL HARDWARE, will not corrode.
STRONGEST WARRANTY available. Heat Exchanger has a LIFETIME Corrosion Warranty. FIVE FULL YEARS on the compressor - TWO YEARS all parts and labor. NOT PRO-RATED.
EASY TO OPERATE, very user friendly thermostat. Just set your preferred temperature and let the Heat Siphon automatically maintain your pool or spa at the temperature you desire within 1F - 24 hours a day, 7 days a week.
QUIET OPERATION, all Heat Siphon models are engineered with a low noise fan design, sound absorbing vacuum-formed plastic cabinet and noise dampening rubber isolation bushings used to mount the compressor. In addition, the scroll compressor provides less noise by operating without the tradition use of valves and pistons.
GREEN- Heat Siphon reduces CO2 emissions by 36 to 46% by using heat from the air instead of BURNING FUEL.

Digital or Analog: Set It-Forget it!

ANALOG MODELS
Rotary knob with different settings

DIGITAL MODELS
Just 2 Buttons

TO KEEP IT SIMPLE, the new DIGITAL Heat Siphon has just two buttons - UP and DOWN. Setting the water temperature and switching modes (pool spa or auto-pic) are simple:

CHANGE the TEMPERATURE - just push and release either button and the current set-point flashes on and off for 3 seconds. Press UP or DOWN to raise or lower the set-point. After 3 seconds a beep tells you it has accepted your new set-point. Simple enough - DONE!
SWITCH TO POOL (or SPA) SETPOINT - Press BOTH "UP" and "DOWN" at the same time and release. The display will flash the current mode ("Pool" or "Spa" or "Auto-Pic"). Then press either key until the mode you want is displayed. In 3 seconds a beep tells you the displayed mode is selected.

Any error conditions are reported and their codes are listed right there on the faceplate so you don't need a manual to tell what they mean.

Three Digital Modes with just 2 Buttons!

All Heat Siphon digital models have three modes - POOL, SPA and Patent Pending AUTO-PIC:

POOL - Heats to the Pool set-point
SPA - Heats to the Spa set-point
AUTO-PIC - Automatically Picks

AUTO-PIC picks the right set-point (pool or spa) all by itself with no wires or other controllers or any connections to anything.

You just turn your valves (manually or motorized) to circulate pool or spa water through your Heat Siphon and AUTO-PIC DOES THE REST.

HOW?- It "learns" the heat-up rates of the pool (slow) and spa (faster) and based on the rate it picks the proper set-point.

Heat Siphon Noise Test Results

Quieter By Design

This noise test shows that a pool pump can produce three times as many noise decibels as a Heat Siphon. With a Heat Siphon Heat Pump you can keep a clear normal level conversation right on top of the unit while operating.

Heat Siphon's Engineering team designed noise quieting into the product by studying the common sources of noise in outdoor air conditioning and heat pump systems and by reducing or eliminating the causes of all major known sources.

Fan blades will create a lot of noise if they are close to any immobile objects. If two or three blades pass an object at the same time then this noise level is doubled or tripled.

Heat Siphon uses a specially designed staggered fan mount which eliminates multi-blade noise and keeps the blades far from any stationery objects to make it whisper quiet.

Our Scroll Models offer the further noise quieted Scroll Compressor for additional low noise operation.

HEAT SIPHON - Highest COP (Efficiency)

Lowest Operating Cost with just enough BTU's

Why Heat Siphon is Designed for MAXIMUM COP not Highest BTUH Heat Output

A normal size residential pool in the colder heating months will require as much as a million (1,000,000) BTU of heat a day to replace the heat lost to maintain its warm water temperature.

To show how EFFICIENCY (COP) and HEAT OUTPUT (BTUH) are related, we created this animation (SEE BELOW) of the delivery of that million BTU's using Heat Siphon and two other "typical" competitive Pool Heat Pumps based on their efficiency and heat output specifications.

The graphic below shows a simulation of the actual daily electric cost over 11 hours for HEAT SIPHON and TWO OTHER BRANDS of 5HP Size Pool Het Pumps:

1st column - the Model SX5HP HEAT SIPHON (COP=6.8 with 95,000 BTUH output) - takes 10.5 hours to deliver the million BTU's

2nd column - Brand X (COP of 6.0 with 125,000 BTUH) - takes only 8 hours to deliver the heat but ends up spending 13% MORE for electricity than Heat Siphon.

3rd column - Brand Y (COP=5.0 with 115,000 BTUH) still gets there in 8.7 hours but costs 36% more than Heat Siphon.

A properly sized Heat Siphon should average about 8 to 12 hours/day of runtime over a swimming season. This guarantees excess heating capacity without over-sizing. The proper design then maximizes COP not BTUH.

LOWER EFFICIENCY (brand x and y) compressors with slightly higher BTUH output are available and cheaper than those Heat Siphon uses. Likewise smaller heat exchangers will cost much less but reduce efficiency further.

Heat Siphon has ALWAYS maintained the design philosophy of maximizing EFFICIENCY. We properly balance all components with our high efficiency compressor, and use oversized heat exchanger surface areas to minimize discharge pressures and reduce amp draw. The right amount of refrigerant charge coupled with properly sized TXV refrigerant flow controls further ensure the highest efficiency at all operating conditions.

At HEAT SIPHON - "WE PERFORM TO KEEP YOU WARM!!" and at the minimum total cost possible!

It's the Most EFFICIENT Pool Heater in the WORLD!

Warm Water at the Lowest Cost Possible. Since 1975 Heat Siphon technology has been the lowest cost method of heating swimming pools in the United States (rain or shine)

HEAT SIPHON Produces Heat at:

1/2 the cost of Natural Gas
1/3 the cost of Oil or Propane
1/5 the cost of Electric Resistance

We believe that sooner or later it will be virtually the only method used. Why? Look at Fuel costs vs. electricity.

The graph shows the historical cost to produce a million BTU's (5 degree F rise in a 24,000 gallon pool) using US City average fuel costs. THE TREND IS CLEAR - Cheap Oil and Natural Gas are scarce and industry, government and university studies have all projected steady price increases while the fuels used to generate 75% of the Nation's electricity (coal, nuclear & hydroelectric) are either ABUNDANT OR INEXHAUSTIBLE.

TITANIUM

Your Pool Heater Can't Live Without it

Because Titanium is so costly heat pump manufacturers have looked at various alternative heat exchanger tubing materials and designs to try to lower their manufacturing costs. Some use only one wrap of titanium tubing in their heat exchanger which drastically reduces efficiency (COP).

In fact Heat Siphon uses TWICE as much titanium as two of our leading competitors. A comparison of COP ratings will confirm this.

Another potential solution is to use less expensive copper tubing just like the gas heaters do. After all, copper is a very good heat conductor.

The problem with bare copper is that it will rapidly corrode in high chlorine pool water and a green copper oxide coating will form which is a very poor heat conductor. worse yet, if corrosion continues then the tube wall will leak and ruin the heat pump system.

To protect the copper some manufacturers have looked at various plastic coatings, however, plastic coatings are just as bad as copper oxide at heat conduction. They insolate the hot refrigerant gas inside the tube from the water outside, lower heat transfer efficiency. This increases the compressor watts and lowers your COP.

In fact, all plastic materials have heat transfer coefficient less than 1% of copper or titanium metal, so even a thin coating of any type of plastic will significantly decrease heat transfer and efficiency. Only the thinnest coating can even hope to come close to bare Titanium in heat conduction and even then the thinner it is the more likely it is to have a small pinhole or incomplete coverage of the vulnerable copper tube underneath.

HEAT SIPHON USES PURE UNCOATED BARE TITANIUM HEAT EXCHANGER TUBING TO ELIMINATE ALL CORROSION AND MAXIMIZE HEAT TRANSFER EFFICIENCY. THAT'S ONE OF THE REASONS WE HAVE THE HIGHEST COP (COEFFICIENT OF PERFORMANCE) IN THE INDUSTRY.

Electrically Isolated Heat Exchanger

SAFE and it Eliminates Galvanic Corrosion

STRAY VOLTAGE STOPS HERE

Hot Refrigerant Gas Can Pass But NOT STRAY VOLTAGE

Although titanium eliminates chemical corrosion in even the harshest pool water a small number of heat exchanger failures occur in pool heaters found to have stray low voltage traveling to or from the pool water through the heat exchanger, which would cause corrosion no matter what metal was used.

With the aid of sensitive digital volt meters, field servicemen can actually measure stray voltage between the heat exchanger and the power supply ground wire or local earth grounding rods required for pool equipment bonding. Floating grounds on power supplies, electronic chlorinators and even underwater pool lights can leak harmless low voltage electricity, less than 3 volts, into the pool which force electrolytic corrosion of the heat exchanger in a matter of weeks.

As the drawing shows, Heat Siphon uses a patented design electrically isolated Titanium fitting which seals the hot refrigerant gas inside the metal tube walls using o-rings, and a separate set of non-metallic insulator rings outside the first seal to break the conduction path normally made by the metal tube. Since the heat exchanger housing is connected to PVC schedule 40 piping and the shell is fabricated entirely out of injection molded or extruded PVC plastic, It also provides isolation from any stray voltage.

This proven heat exchanger & fitting design eliminates galvanic corrosion as a source of heat exchanger failure while also making the heat exchanger safer by electrically isolating it from the rest of the heat Siphon and from your pool water.
