Pool heating heat pump

Gas Pool HeatingCapture Florida's Warm Air Efficiently

  • Year round swimming
  • Low operating costs
  • Quiet operation
  • Non-polluting heat source
  • 5 year manufacturers’ warranty
  • Titanium exchanger protects against chemical damage

Swimming pool heat pumps capture warm air and transfer it to your pool. They work best in air temperatures above 45–50°F, so they are very effective in South Florida’s mild climate. Swimming pool heat pumps do not have temperature limitations during cooler winter months and are not impacted during cloudy or rainy weather, so they can offer more consistent heating than a solar pool heater. Electric heat pumps are environmentally friendly and unlike gas heaters, they work without fossil fuels.

System Function and Sizing

A swimming pool heat pump extracts heat from the outside air and pumps the heat to your pool water. A high efficiency heat pump can heat your pool or spa to temperatures up to 104˚ F. Swimming pool heat pumps are sized based on your heating needs; using factors such as your pool size, temperature expectations and cover use. We recommend using an energy-efficient heat pump with a Titanium heat exchanger and scroll compressor which can offer a lower annual operating cost while protecting the unit from chemical damage.

Your Investment

The cost to install a swimming pool heat pump is comparable to the cost of installing a solar pool heater, approximately $2500.00 to $4000.00. Annual operation costs will vary based on pool temperature settings, unit efficiency and pool cover use during cooler months. Heat Pumps require annual check ups and with proper maintenance will provide up to 10 years of worry-free operation.


How does a swimming pool heat pump operate?

How a swimming pool worksSwimming pool heat pumps use electricity to capture heat and move it from the air to your pool. They do not generate heat, but rather work just like central air conditioning units, only in reverse. Instead of removing heat from the inside of your home and expelling it to the outside air, a pool heat pump takes heat out of the outside air and transfers it into your pool water.


What size heat pump will I need?

Heat pumps are sized based on your unique situation. Factors such as pool size, temperature expectations, water features of your pool (spas, waterfalls and fountains), and blanket use contribute to properly sizing for your pool.

Do I need to use a pool cover?

A cover is not necessary for most of the year in South Florida; however using a pool cover can cut your heat pumps winter time operating expenses by up to 50%. Very simply, a pool cover will keep the heat in your pool. Besides offering energy savings, pool covers also do the following: conserve water caused by evaporation, reduce the pool's chemical consumption by 35%–60% and reduce cleaning time by keeping dirt and other debris out of the pool.





Gas Pool Heating

Heat PumpUnlimited Temperature, with quick results

  • Fastest style of pool/spa heating available
  • Low emissions for a small footprint
  • Condensation-free operation
  • High efficiency units
  • On demand heat

Gas Pool Heaters use either propane or natural gas. As the pool pump circulates water, it is passed through the heaters gas combustion chamber, which super-heats the water and returns to into the pool. Gas heaters are used if you require very warm spa or pool temperatures (85-104˚F degrees) regardless of the weather or climate. This might be important if you have an in ground spa or swim for therapeutic exercise. A gas heater is currently the most expensive way to heat your pool and are best when installed as a hybrid system and used as a backup heater to supplement a primary solar pool heater or pool heat pump.





Hybrid Pool Heating

Hybrid DiagramThe Best of Both Worlds

  • Swim year-round
  • Lower energy costs to heat your pool
  • 12 year manufacturers’ panel and stainless steel hardware warranty
  • Enjoy maximum comfort and minimal maintenance
  • Environmentally safe way to heat your pool
  • State of Florida Incentives available

If high energy bills are keeping you from using your pool heater as often as you would like, than a hybrid system is the answer for you. By keeping your existing electric heat pump or gas heater, and adding a solar pool heating system you can stop worrying about high energy bills and start enjoying a warm pool year round.


If you already have an electric or gas pool heater, you know the advantages of having a pool heating system: Getting more enjoyment from your pool with a longer swim season, maintaining a comfortable temperature every time you take a dip, and adding to the valve of your home. In the hybrid system, the primary source of heat is a solar heater, and your existing gas heater or electric heat pump is used as a backup heating source. Since solar energy is free, this enables you to significantly reduce your operating costs compared to using a gas or electric heater alone. And by using less fossil fuel, a hybrid system not only saves you money it also has less environmental impact.
