How Do Heat Pumps Work To Keep Your Pool Warm?


Most homeowners love the idea of having a pool in the backyard or somewhere in their compounds. But in as much as they would love to use their pools throughout the year, they are restricted by the condition of the weather, mostly cold winter season.

And when it freezes in the North or in any other country that experiences winter, it becomes a challenge to use the pool, unless a heat pump is used to warm the water.

So it emerges that all homeowners who have a pool must consider investing on a heat pump if they want to enjoy a longer swimming season. When others stop using their pools, they will be comfortably enjoying swimming because cold temperature is nothing to worry about when the water is warm.

How heat pumps work?

There are several types of heat pumps to use in a pool. Most brands will shut down the moment outside temperature drops below 55° degrees. But some can continue operating in the low 40’s or in mid-to-low 20’s.

These models have different names because they are manufactured by different companies. They could also be referred to as icebreakers, heat/cool heat pumps or reversible heat pumps.

Whether in cold or warm temperature, a heat pump will work the same way. Through the help of an in-built evaporator coil, a heat pump utilizes nature’s free heat to warm your pool water, and this is a good idea since you won’t spend on electricity.

During winter, a heat pump will begin freezing the condensate which forms normally on the evaporator unit. If you own a standard heat pump, it will automatically shut down at this point to avoid mechanical damage likely to be induced by the icy condition.

When this happens, an in-built Hot Gas Defrost unit will make use of the reverse cycle system whose task is to reverse the flow of the refrigerant gas. As a result, this will defrost the evaporator coil, and will let the heat pump continue its operation in cold weather.

The benefits

– You will extend your swimming season because using the pool is not dependent on weather condition.

– An Eco-friendly heat pump like the one mentioned above doesn’t use electricity, and this allows you to enjoy hot water without paying a single cent or increasing your carbon footprints.


If you don’t properly winterize your heat pump, it will easily get damaged. You don’t want to incur a huge cost in fixing it. Repair bills can be quite high.


Know the manufacturer limitations of your swimming pool heat pump and you’ll be safe from damaging the unit. Also, if you want to keep enjoying warm water during cold weather, having and maintaining a heat pump should be at the top of your priority list.
