How The EUS Heat Pump Works

Cold water is no fun. The solution is to heat your pool so that every day the water is at the temperature you desire. A heat pump makes this possible.

The EUS heat pump moves heat from the air to the water. This method has great advantages over gas-powered heat pumps which must create heat to pass to the water. Accordingly, the EUS heat pump operates on a fraction of the energy required by conventional heaters.

Your cost is 75%-80% less than propane (LP) gas systems and 50%-55% less than natural gas systems, based on national average prices. Only a small amount of electricity is used to operate a fan which pulls the warm air through the evaporator where the air gives up its heat, converting the liquid refrigerant into a gas.

A small amount of electricity is used to operate the compressor which compresses the heated gas to an even higher temperature. Then, this hot gas gives up its heat to the incoming pool water in the condenser (heat exchanger). Finally, the refrigerant condenses back to a liquid and the cycle repeats.

What Makes EUS a Better Buy?


With more than 20 years experience building heat pump water heaters, we’re the pioneer in the industry. Our employees are skilled craftspeople who take great pride in their work. We never cut corners to save money on parts and labor. We use only the best quality components.


With a five-year warranty on all parts and labor, you can see why we use only quality components. It doesn’t make sense to save a few dollars on cheap parts and then spend big bucks on repairs for the next five years! EUS stands behind its five-year warranty which comes with the unit at no extra charge. Paying extra for an extended warranty “backed” by some warranty company is risky for the customer. Warranty companies often stick closely to the letter and may not cover the problem. Also, they don’t care if the customer is satisfied or not with their decision. EUS cares very much and that’s why our warranty covers all parts.

A Unique Heat Exchanger

It’s the only heat pump in the entire industry that does not let the corrosive pool water touch metal — anywhere. Nearly every other manufacturer’s heat exchanger routes the pool water through a metal tube. Stains on the pool bottom are a clue that metal is being dissolved from the heat exchanger and deposited in the pool. EUS builds a unique, coated heat exchanger which isolates the water from the metal so corrosion and undue wear cannot occur.


EUS offers the highest quality at an excellent price. Many manufacturers have cut prices and sacrificed value to become more competitive with EUS. We remain firm on value. For example, we use two layers of evaporator instead of one, a $5 weatherproof seal instead of a 30¢ plastic seal, and a vinyl dipped evaporator screen instead of painted wire or plastic.

Full-Flow For Better Heat Transfer

Many competitive units use heat exchangers that cannot accept normal pump flow of water and have internal by-passes. This allows the full flow to enter the unit, but only part goes through the heat exchanger while the rest is by passed (unheated) back to the pool. EUS units take up to 70 gpm in the larger units and up to 50 gpm in the smaller units. Therefore, EUS units heat all the water, not just part of it.


EUS has chosen to avoid extra lights, digital readouts, dials and buttons. Extras may appear impressive but often cause more problems that are costly to repair or replace. EUS concentrates only on those features that meet our goal — to heat water more efficiently and economically.

Selecting The Right Model For Your Pool

The right EUS heater for your pool depends on several factors:

  • The size of your pool
  • The average air temperature
  • Use of a pool cover
  • The desired pool temperature
  • The amount wind, sunlight and shade
  • Run time of the filter pump

For larger pools, we suggest the PE52 Mark V (5 hp) model. This unit produces in excess of 116,000 btu/hr. Also available with hi-efficiency Scroll compressor.

For average pools, we suggest the PE42 Commander (3.25 hp) model. This unit produces in excess of 75,000 btu/hr.

All models include:

  • Durable non-corrosive cabinet of heavy-guage, UV-treated plastic that won’t fade or deteriorate in the worst climatic conditions: salt air and baking sunshine.
  • Evaporators with raised lance fins for maximum heat transfer and protected by vinyl-coated steel screen.
  • Unique heat exchanger that is protected from contact with damaging, chemical-treated pool water.
  • Crankcase heater to protect the compressor.
  • A five-year warranty on all parts and labor.
