How to Choose the Heating Method That’s Right for Your Pool and Spa

Heating Your Pool and Spa this Fall

There are a number of ways to think about heating pools and spas. Your specific sensory desires, your schedule, the climate where you live and the heating technologies available all play a role in how you should approach making your pool or spa warm and welcoming. So, how do you pick the heating method that’s right for your pool and spa?

Two Popular Heating Methods

Most stand-alone pools and pools with attached spas use either natural gas-fired heaters or electric heat pumps for heating.

Natural gas is the most widely used energy source for pool and spa heating. In natural gas heaters, a gas flame transfers heat to your pool’s water through a metal heat exchanger. This technology provides the fastest and most reliable heat in colder climates, and is especially popular with pool/spa combinations where the goal is to quickly get spa water up to comfortable, soaking warmth.

Heat pumps work differently. They use electricity to circulate a refrigerant through the unit to extract free heat out of the air. They extract the heat using the thermodynamics of evaporating and re-compressing refrigerants. This process uses far less electricity than it would take to produce the same amount of heat with an electric heating element. Heat pumps are popular in many climates and are for pools and spas where the goal is temperature maintenance, as opposed to fast heat-up.

Add to the Warmth with Automation

Having warm water ready no longer means you’re tied to controls in your backyard. An automation system can allow remote operation so you can control and preset your pool’s heating from wherever you are.

Extending the Pool and Spa Season

If you’re like other pool owners, you want to extend your pool season beyond just the summer months. Depending on where you live and your water temperature goals, you may want to consider both a heat pump and gas-fired heater. Why? As nights get longer and cooler, a heat pump alone might not be able to maintain desired temperatures. This is where a supplemental gas-fired heater can be used at night to keep the water comfortably warm and provide fast heat-up of an attached spa.
