Electrical

The Nano 3 and 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.

Bypass Kit

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.

Wi-Fi Connectivity

The Poolex Nano features 2.4Ghz Wi-Fi connectivity via the Poolex App (you can also use the Smart Life App).

Once you have downloaded the Poolex App (or Smart Life) will need to create an account before you can continue to pair with your heat pump and control it remotely.

Once you get to the point of adding a device in your App you will need to activate the pairing mode on your Nano, to do so please follow this procedure:

Positioning

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.

The Poolex Nano comes with a comprehensive warranty package:

Can I use the Poolex Nano heat pump for an above-ground pool?

Yes. The Poolex Nano is specifically designed to heat small above-ground pools.

There are a few factors to consider before making your choice, including your pool size, what water temperature you would like, the average outside temperature where you live and how long you would like to use your pool, please head over to our heat pump size guide for more information on choosing the correct size heat pump for your pool.

What are the main features of the Poolex Nano heat pump?

How energy efficient is the Poolex Nano?

The Poolex Nano is very economical, featuring a Coefficient of Performance (COP) of 5.5 at air temperatures above 24°C. This means that for every £1 spent on electricity, the unit delivers up to five times the heat output into your pool (COP drops when the outside temperature is cooler).

Will the Poolex Nano fit in a small garden or patio?

Yes. The Poolex Nano features an ultra-compact footprint designed specifically for tight spaces, small gardens, and patios. Additionally, it operates with whisper-quiet technology to ensure it does not disturb you or your neighbours.

Can the Poolex Nano heat a pool in cooler weather?

Yes. The automatic defrosting function will prevent ice build-up on the back of the unit without requiring manual intervention, however the ability to heat efficiently at lower air temperatures will depend on the size of your pool and the water temperature you require.

We are more than happy to advise on the correct size heat pump for your pool or you can head over to our heat pump size guide for more information.

Should I insulate my pool?

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.
