The performance of the pool heat pump should be adapted to the size of your pool. diy pond pumps while for smaller pools with less than 30m³ a pool heat pump up to 10kW is sufficient, for medium-sized pools with 30 to 40m³ you should rather choose a pump with 11 to 13kW heating capacity.
Basically, the larger your pool is, the more sensible an inverter model is for you – simply to shorten the heating time and thus heat more efficiently, but also because these versions are much quieter and you or your neighbors are exposed to a less disturbing noise for less time.
Hint: Good pool heat pumps have a sound output of less than 50 dB, which can be roughly equated with the volume of birdsong or refrigerator noise. The best models are only audible at about 30 dB, which is the same as the noise in a quiet room where no one is talking.
In addition, the heating power in relation to the pool size is crucial. While for smaller pools with less than 30m³ a pool heat pump up to 10kW is sufficient, for medium-sized pools with 30 to 40m³ you should rather choose a pump with 11 to 13kW heating capacity.
In order to preserve the heat once gained, it is also advisable to cover the pool with a solar film when not in use and overnight.
Very large pools with more than 50m³, on the other hand, should be heated with a seating capacity of more than 15kW if you want to proceed efficiently. The evaluation of efficiency also makes it easier for you to take a look at the so-called COP value. COP stands for Coefficient of Performance and indicates the ratio of required electricity and heat generation. From a COP value of about six, high efficiency can be assumed, from a COP value of 10 from very high efficiency.
If you want to use your device in a particularly environmentally friendly way, you can operate your pool heat pump with solar power, which you generate, for example, via solar panels on your roof or a solar thermal system.
There are also pumps that are equipped with their own solar panel. The advantages and disadvantages of purchasing such a device for you can be found in the following overview:
Advantages
- particularly flexible with regard to placement
- Energy-saving devices
- autonomous power supply
Disadvantages
- Performance depends on sun incidence
- generally, often lower heating capacity
Also, check the possible operating temperature specified by the manufacturer. calculate pond pump size while some devices do not have specific restrictions on the prevailing ambient temperature, many others only work optimally in a certain temperature range.
Some, for example, are already able to heat up the sucked-in air enough at -5 degrees Celsius to heat the pool water. Others require at least eight or even twelve degrees Celsius. An upper limit is also often specified in these cases, which is typically between 35 and 45 degrees Celsius.
