Swimming pool heat pump technology

Calorex heat pumps provide a solution to temperature control which will reliably and economically heat or cool a swimming pool, regardless of ambient air temperature and location.

Enjoyable swimming

Dependable swimming pool temperature control is a key feature to enjoyable swimming. For a swim to be refreshing and invigorating the pool water must be the right temperature for the swimmer, regardless of the influence of seasonal weather.

Winter heating

During winter, swimming pools continually evaporate water and radiate heat. The combination of these factors causes heat loss which must be replaced through a heater if comfortable water temperatures are to be maintained.

Summer cooling

During summer, swimming pools are subjected to massive solar gain. Coupled with high ambient humidities which prevent pools from cooling through evaporation, swimming pool water will become uncomfortably hot unless dynamically cooled.

The heat pump cycle

Calorex heat pumps are specifically designed for swimming pool heating and cooling.

This means that all components used in their construction are designed to give maximum efficiency and reliability at swimming pool conditions, even in the toughest climates.

Why heat pumps?

Heat pumps are recognised as the most sustainable way to dynamically heat or cool swimming pool water saving both energy and operating costs.

Unlike electric flow heaters and boilers that can only provide pool heating. Calorex heat pumps will automatically either heat or cool your pool without the need for additional equipment.

As an added bonus, a Calorex heat pump will produce up to five times the energy it consumes, dramatically reducing the energy consumption of your swimming pool. They are quick to install and easy to operate.

Fully self-contained units, Calorex heat pumps easy to install and when it comes to operation, units offer quiet, reliable and safe performance.
