Quality

The cabinets are steel, first galvanised and then coated to provide resilient protection against external elements. Pool water
heat exchangers are of high quality to ensure maximum resistance to pool chemical corrosion.

All models now include a titanium heat exchanger with a five year warranty, plus digital controls.

Each unit is thoroughly tested and inspected and must meet a precise performance standard before leaving the factory. The
Calorex factory and products are approved to several internationally accepted standards of quality and safety.

All Calorex equipment is fully guaranteed and dispatched complete with comprehensive instructions.

Easy 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.

The Pro-Pac range can be installed outdoors or inside a plat room.
