How a Pool Heat Pump Works

A heat pump works like an air conditioner in reverse. It draws heat from the outside air through a refrigerant circuit and passes it to the pool water in a heat exchanger.

For every unit of electricity it uses, it delivers several units of heat. Output drops as the air gets colder, which is why sizing for your pool and season matters.

Heat Pump or Solar Heating?

Solar pool heating costs almost nothing to run but depends on the sun and needs roof space. A heat pump costs more to run but heats on cloudy days and at night, and lets you set the temperature you want.

Many pools use both: solar for most of the season and the heat pump to top up in cooler weather.

Sizing a Pool Heat Pump

The right size depends on the pool’s volume and surface area, the temperature you want, the months you want to swim, and whether you use a cover. An undersized pump never reaches temperature; an oversized one costs more than it needs to.

A pool cover makes the biggest single difference, because most heat escapes through the surface.

Inverter Heat Pumps

Inverter heat pumps vary their output to match the heat needed instead of switching fully on and off. They are quieter and more efficient than fixed-speed units, but cost more upfront.

Installation, Servicing and Repairs

We place the unit where it gets good airflow, plumb it in after the filter, and have the electrical supply connected safely. Servicing covers cleaning the air coil, checking water flow and controls, and looking for refrigerant problems.

Common repairs include flow errors from a dirty filter or weak pool circulation, ice on the coil in cold weather, and units that run but do not heat.

FAQs – Pool Heat Pumps

1. How much does a pool heat pump cost to run?

It depends on the pump’s size, the temperature you set, whether you use a cover, and your electricity tariff. A heat pump uses a fraction of the power of an electric element heater for the same heat.

Yes, but output drops on cold Highveld nights. A correctly sized heat pump with a pool cover can keep a pool swimmable well beyond summer.

It is strongly recommended. Without a cover, much of the heat the pump adds is lost overnight through the water’s surface.

With regular servicing, a good heat pump often lasts ten years or more.
