How Can I Control The Temperature Of My Swimming Pool With a Heat Pump?

Many of our sales people often get asked this question by the homeowners. Let’s face it, how many of us actually read a manual? I know I don’t! So, to help you figure out how to control the temperature on your swimming pool utilizing your swimming pool heat pump, we figured an article on this subject was in order.

How it Works

Heat pumps have a built-in thermostat most units come with dual digital controlled thermostats that can handle both your pool and your spa. Once the desired temperature is reached, the thermostat will shut the unit off or turn it back on if the water temperature drops by more than two degrees.

Some manufacturers have what they call an “Auto-Temp” feature. This will override your pool system’s time clock and turn the heat pump on or off to maintain the desired temperature. One drawback to this is that the unit can be turned on in the middle of the night and it can run until the morning, unless you like to swim very early in the morning, this can be a huge waste of energy due to low night time air temperatures.

How to Set the Temperature

Some units, like AquaCal, have a simple display with arrows up or down and pool and spa indicators, simply choose the body of water you want to set the temperature for press up or down until you reach the desired temperature and sit back and relax.

Older or non-digital heat pumps have knobs that you can turn to set your temperature and the body of water you are heating. Though still dependable, they are not as precise as the digital controlled units.

With the ever changing world of technology, many pools have control systems that operate all of the equipment needed for a swimming pool. These control systems can work from systems as simple as a time clock to more elaborate systems that use control panels in the house, hand held controllers or even systems that work from your smart phone. Check with your pool professional to see what options best fit your family and system’s needs.

There you have it, a simple answer for the frequently asked question on controlling the temperature for your swimming pool heat pump and also a little information as to how it works. If you have any further questions regarding this subject or any other topics for pool heat pumps please do not hesitate to ask or leave any comment you may have.
