6. Installation

The Calorex Swimming Pool Heat Pump is designed intelligently and exceptionally compact for ease of installation. One of the simple but handy design additions on the Calorex Heat Pump is the integrated flow switch which will sense the water flow and automatically start the heater when the pool pump starts and stop it when the pump shuts off. Simple, but very handy. We can also offer an installation service if required.

We recommend that a bypass is installed to allow the heat pump to be drained in winter if not in use. We sell bypass kits if required.
