Instantaneous water heater for the pool Checklist: These features are important in the test
- Pool size: Instantaneous water heaters are primarily suitable for pools smaller than 20 cubic meters. For larger pools, the heating capacity is lower and a heat pump makes more sense. Nevertheless, there are a few instantaneous water heaters with a higher output that are also suitable for larger pools.
- Heating temperature: When purchasing instantaneous water heaters, attention should be paid to the maximum heating temperature. Most models manage to heat the pool to 35 to 40 degrees. On some models, a temperature can be set which is then maintained by the heater.
- Power supply: Instantaneous water heaters must be connected to a power supply in order to heat the pool. This should be taken into account, especially for above-ground pools in the garden, and an extension cable or connection should be installed if necessary.
- Hose diameter: Hoses with a diameter of 30 to 32 mm are usually used for pools. When purchasing an instantaneous water heater, make sure that the pool pump hoses fit.
