What to Consider When Sizing a Swimming Pool Heat Pump

When working out what size heat pump will be required for your pool, there are some factors to consider. These factors include:

  • The climate
  • The size of the pool
  • Your swimming habits

To ensure that you get the most out of your heat pump, you will first need to choose one suited to the conditions where it will be based. By taking this into account, your heat pump will provide a much more consistent and cost-effective performance.

Another thing to check is if the heat pump will be the right size, but how do you know what heat pump you will need for your pool?

Pool Size Vs Swimming Pool Heat Pump

The pool size is an essential factor when sizing a pool heater; the volume of water within the pool will determine how powerful the pump will need to be. Our Aqua inverter heat pumps are designed to maintain common swimming pools with a power of 17.3kW.

Naturally, the bigger the pool, the more powerful the pump should be. When you size a pool heat pump, you will need to know the pool's volume.

Climate Vs Swimming Pool Heat Pump

It's essential to consider the climate of where the heat pump will be situated, as this will influence how hard the heat pump will have to work to warm up the pool.

If you live in a warm area and own an average-sized pool, you can easily invest in a smaller-to-standard-sized pool heat pump. Pool owners located in a much colder climate will need a much more powerful swimming pool pump.

We recommended considering the Aqua Inverter Turbo-Pro - TurboSilence Heat Pump that is equipped with powerful heat-exchanging technology.

Swimming pool heat pumps will still work well in colder climates; they will just need to work harder. Take note of the water's temperatures during the colder months, as this will give you an insight into how hard the pump will need to work.

 

Swimming Habits Vs Swimming Pool Heat Pump

Your swimming pool habits won't necessarily impact the size of the heat pump, but they will influence the heating speed needed.

More robust heat pumps will naturally have a much better ability to quickly heat a pool. Even if you live in a warm environment, you might choose to purchase a strong heat pump to accommodate your constant use of the pool.

That said, heat pumps are designed to provide resilient and reliable heating in a wide range of climates, so a standard-sized heat pump should suffice. However, for extra protection, consider a heat pump cover to protect it against harsher weather.

 

How to Calculate Required Swimming Pool Heat Pump Size

The heating capacity of swimming pool heat pumps is usually measured in kilowatts (kW). The size of the pump you need is according to the required kW per hour of the swimming pool.

It's worth bearing in mind that different heat pumps have different coefficients of performance (COP), meaning specific models have different power needs. Your best bet is to find a model of heat pump you want, then check the manufacturer's notes to determine which size you need.

However, if you want a rough guide in terms of what to look for, here are some averages from across our range:

Pool volume (m3) Heating capacity in cold air (15C) Heating capacity in warm air (26C)
20-40 6kW 8kW
40-60 9.5kW 13kW
60-80 15kW 25kW
80-100 18kW 30kW
