Is the water in the pool too cold? With a pool heater above ground, the water can be set to the desired temperature and heated.
Heat pumps Advantages:
Unlike other pool heaters, pool heaters above ground use their ambient heat to heat the pool. The heat from the air is converted into energy by the heat pump to heat the water. This means that the outdoor pool can still be used even at low temperatures.

Buy a pool heater above ground:
How to make the right decision
Regardless of the outside temperature, the pool can be used all year round. Pool heaters above ground are a simple and practical way of using the ambient air to heat the cold pool water.
The following points should be considered when purchasing a pool heater above ground:
Model: On/off heat pump or inverter?
Heat pumps still need a basic energy source so that they can use ambient heat to heat the water. Gas, electricity or solar energy can be used for this.
The decisive factor is whether it is an on/off heat pump or an inverter heat pump. What is the difference?
- On/off heat pump: On/off heat pumps can only be operated at one power level. The pump switches on automatically when the temperature falls below the desired value and switches off again automatically as soon as the value is reached.
- Inverter heat pump: Inverter heat pumps have several output levels. They are more energy-efficient and significantly quieter during operation. The output of the heat pump is continuously adapted to the heating requirement. This allows the heat output to be set and heated precisely.
We recommend: Inverter heat pumps are more expensive than on/off heat pumps. The output of an on/off heat pump is perfectly adequate for normal everyday use. If you want to maintain certain temperatures in the pool for longer, it is better to use an inverter.
Function: What should the heat pump be able to do?
Heat pumps use a compressor to extract heat from the ambient air and transfer it to the pool water via a heat exchanger. The output of the heat pump can be read from the pump’s kilowatt rating.
Larger pools need a more powerful pump: up to 20 cubic meters, a pump with 6 kW is sufficient; for 30 to 40 cubic meters, a pump with 11 to 13 kW should be used.
Water flow rate:
The water flow rate indicates how much water flows through the heat pump per hour and accordingly how much water can be heated. A high water flow rate heats the pool faster than a low water flow rate.
A heat pump that has a water flow rate of 30 cubic meters of water per hour needs 10 hours to completely heat a pool with a water content of 30 cubic meters. Depending on how warm the water is at the time you start, you can of course bathe in it beforehand.
COP or efficiency:
When purchasing a heat pump, the COP (coefficient of performance) or efficiency should be taken into account. The COP describes the ratio between the heat generated and the electricity required to generate it. A high COP means that the heat pump provides a high heating output with low power consumption.
The outdoor temperature also influences the heat pump’s output. The warmer the outside temperature, the easier it is for the heat pump to heat the water.
Storage: Where should the heat pump be located?
Heat pumps are connected directly to the water filter system and to a power source. For garden pools, it is important that there is a power connection or that an extension cable is laid. For larger heat pumps, you should consider whether a normal socket is sufficient.
To ensure that the pump can be used for a long time, it should be cleaned regularly. To do this, the following steps should be followed:
- Disconnect the power supply to the pump
- Clean the vaporizer with a brush and water
- Metal sheets must not bend!
- Clean the ventilation grille with a brush
- Clean the outside of the appliance with a little water
As the heat pumps draw their heat from the ambient air, they need sufficient ambient air. The heat pump should therefore be free-standing. It is at its best when it has no backward limit and a minimum forward limit. 4 to 5 m of space.
To extend the service life of the heat pumps, they should be installed outdoors under a roof. Most heat pumps can also be used at sub-zero temperatures. The pumps can be used from -5 degrees to 43 degrees. To prevent the pumps from overheating, it is important to ensure that there is sufficient space around the pump.
