What types of pool heat pumps are there?

Pool heat pumps can be divided into different categories. best garden hose in our purchase advice, we would like to introduce you to the two most common model types briefly and clearly, so that you can plan the connection of a new pool heat pump completely.

Conventional pool heat pumps

  • slightly higher power consumption compared to pool heat pumps with inverter
  • average to good COP values
  • slightly higher operating volume
  • less compact pool heat pumps (enough space to plan)
  • many different models offered
  • rather cheap pool heat pumps

Inverter Pool Heat Pumps

  • particularly energy-efficient
  • high COP value
  • mostly very compact pool heat pumps
  • Low volume during operation
  • particularly durable and resistant
  • Higher acquisition costs with a smaller offer

Pool heat pumps in tests: How do you find the best pool heat pump for your pool?

Once you have decided whether you want to buy a cheap and simple, conventional pool heat pump or an inverter model, it is important to check further specifications. The most important selection criteria include:


  • Size
  • Volume
  • Electricity consumption
  • Heating capacity and maximum temperature
  • Connection
  • Accessories and additional functions

Of course, it is particularly important that you choose the perfect size of the pump for your pool. But how should you plan the dimensioning of your pool heat pump according to your pool size?

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. best and strongest 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.

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 heating 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.
