Heat Pump

A Heat pump is the most energy efficient solution to heat your pool in warmer climates. In fact, heat pumps provide energy savings up to 70% over gas heaters. Heat pumps capture heat from the surrounding air to heat the pool water and are particularly good if you want to maintain a constant pool water temperature.

Gas Heat or Heat Pump?

Gas Heat or Heat Pump?

Whatever your climate, warmer or cooler, you will want to experience the comfort of heating your pool. Even if the air temperature seems warm enough, it doesn't necessarily mean your pool's water is comfortable enough to swim in.

The only way to continuously enjoy your pool is to heat the water to the perfect temperature, there are pool and spa heating solutions for every application, budget and climate - let's explore them.

Gas Heat

The greatest benefit of gas pool and spa heaters is that they heat your pool and spa in minutes or hours versus the hours or days required initially to warm the pool with a heat pump. Gas heat is ideal if you don't use your pool or spa on a daily basis, and just want to heat your pool or spa as needed. Key attributes of Hayward's gas pool heaters are that they're environmentally responsible and lower the cost of ownership via its energy efficiency and reliability.

Another benefit of gas pool heaters is they perform well in any climate. They'll heat your pool and spa on the coldest of days versus the limits of a heat pump.

Heat Pumps

Heat pumps are incredibly energy efficient at maintaining a constant water temperature and can deliver savings of up to 70% versus a gas heater. Heat pumps are very efficient because they utilize the heat from the surrounding air to heat the pool's water versus burning natural gas or LPG.

Heat pumps work well in warmer climates but are at a disadvantage in colder climates. Although a heat pump will operate at temperatures above 10 degrees celsius, cooler air temperatures below 10 degrees celsius may not have sufficient heat in the air to keep your pool as warm as you desire. At these lower temperatures a heat pump is likely not the best option for heating your pool.

A Hayward heat pump model is the most efficient way to heat or cool the temperature of your pool or spa. Warmer climates and especially pools and spas with dark surface finishes benefit from the water being cooled. If you live in a climate that can become extremely hot the heat/cool heat pump is a perfect choice.

Combined Benefits – Gas Pool Heater and Heat Pump

A gas heater and heat pump combination will deliver energy savings utilizing the heat pump a majority of the time, and switching to a gas pool heater when the temperature drops. Other benefits include:

  • Most energy efficient way to heat or cool your pool and/or spa in any climate
  • Heat pump efficiently maintains ideal pool temperature while gas heater rapidly raises spa temperature on demand
  • The ability to choose between heat pump or gas heat on cooler days and in colder climate.
