Air heat pumps

With an air heat pump from Steinbach, you can extend the summer season and keep the water in your pool warmer for longer. Thanks to the integrated cooling function, the air heat pump can also cool the pool water if it gets too hot. Therefore, you can enjoy pleasant refreshment in the pool even on hot days.

Make sure that the air heat pumps are only suitable for outdoor temperatures up to a minimum of 5°C. If it is colder outside, you should winterize the pool and the heat pump to avoid frost damage. In addition, the set water temperature must not differ from the ambient temperature by more than 15°C.

Inverter heat pumps

Our inverter heat pumps, which include the Silent 2026 models, are extremely energy-efficient, adapt automatically and, thanks to a touchscreen display, LED status indicator and advanced control options, offer even greater control whilst minimising energy consumption. Thanks to their exceptionally quiet operation, you can enjoy your pool to the full and transform it into a relaxing oasis.

Our heat pumps without inverter technology

Heat pumps without inverters operate at a constant output and cannot react as efficiently to weather conditions as inverter heat pumps. Nevertheless, they offer a more cost-effective and environmentally friendly option compared to electric pool heaters.

Permanently active, multi-stage frost protection

The automatic frost protection ensures year-round operation. It is activated at an air temperature of 5°C. At air temperatures below 0°C or a water temperature below 2°C, the circulation pump runs continuously. If the water temperature drops below 1°C, the heating switches on. Frost damage is not covered by the warranty.

Good to know
Why is it advisable to use a bypass-set and an additional filter pump?

Regardless of the filter system used, an additional filter pump can be used to create an efficient circuit that can help to save energy. The heat pump itself is controlled via the operation of the charging pump (e.g. via a timer or solar).

For an even more efficient use of the heat pump, we recommend our Steinbach bypass-set (art. no. 060045). With this set, you can regulate the water flow and the water circuit individually. With the solar-powered circulation pump (art. no. 040613), the required volume flow can be automatically linked to the time of day via the heat pump.

Things to know about the pool heat pump

By using a heat pump, the pool water is slowly heated up to the desired temperature. The air heat pump of the Waterpower series from Steinbach is available with a heating capacity of 5100 watts and 8000 watts with a cooling capacity of 3400 watts and 6000 watts. The cooling function is already included in the Waterpower series at no extra charge. The temperature rise per hour depends on several factors and varies depending on the size of the swimming pool and model of heat pump. At 10 cubic metres, the pool water of the heat pump with 5100 watts output heats up by an average of 0.4 degrees and by 0.7 degrees with the 8500 watts output heat pump per hour. Please note: the larger the swimming pool, the longer it takes to heat the pool.

By using an air heat pump, the swimming season can start as early as spring and be extended into autumn. In the summer months it is usually not necessary to use a pool heater, as the sun and the outside temperature heat the pool water sufficiently.

The Waterpower 5000 heat pump can heat or cool pools with a water capacity of up to 30,000 litres, whereas the Waterpower 8500 heat pump can heat or cool up to 55,000 litres. The operating principle is relatively simple and effective: the heat pump draws energy from the ambient air and transfers it to the pool water, which then begins to heat up. The heat exchanger is made of stainless titanium for a long service life. The air heat pump is also suitable for salt water pools due to the titanium heat exchanger. The heat exchanger is a device to transfer the heat from two separate liquids.

The installation of an air-heat pump is possible at any time, even at a later date, but in this case a bypass is necessary. The bypass is used for the targeted control of the water flow and is used for heat pumps as well as for solar systems. All data and functions can be called up quickly and easily via the integrated control system with LCD display.
