Sizing

Learn more with our handy sizing guide, find out what kW heat pump you require for your pool or pond

COP

Put simply, COP stands for Coefficient of Performance and is quoted as a number, such as 5.5, this means for each kW of energy used you get 5.5kW of heat output – the higher the output, the lower your running costs.

Installation

If you are thinking of heating your pool you should cover the pool when not in use as 80% of heat loss occurs through surface evaporation, a separate solar or bubble cover is a worthwhile investment if you don’t have an existing cover.

With an above ground pool it is especially important to keep it covered as these pools are not well insulated against heat loss – additional insulation around the sides and bottom of an above-ground pool can help to retain valuable heat – in fact properly insulating your pool can extend your season or even reduce the size of heat pump required.

The 3.5 and 5.5 models come fitted with a mains cable as standard, making them suitable for RCD protected outdoor sockets, this cable can be removed and the unit can be hardwired if required.

Water inlet and outlet connections are 32mm, the unit comes supplied with PVC hose connectors that are suitable for 32/38mm hoses.

If the flow rate through your heat pump is too high it can take longer to heat your pool or you may struggle to achieve your desired temperature, our bypass kit for above ground pools optimises the flow rate to maximise the heat transfer to your pool water. A bypass kit also allows the circulation and filtering of pool water without heating and for winterising your heat pump.

Your Nano swimming pool heat pump should always be installed outside, the metal case provides necessary protection from the weather.

The manufacturer literature may state that the heat pump should be positioned above the waterline, the assumption being that pools are in-ground, therefore the heat pump would sit at ground level.

If you have an above-ground pool please position your heat pump at ground level (therefore below the waterline), there is no need to elevate the heat pump.
