Energy efficient solutions for your water heating

Heat pump hot water is a more energy efficient and economical way to heat water, compared to standard electric cylinders or gas water heaters. With heat pump technology, you can save up to 70% of water heating costs - which is usually 30%-45% of our total power bill.

What makes Calitec different?

Our split system is designed with Kiwi homes in mind and is easy to install in both new and existing homes. It provides maximum flexibility, with the hot water cylinder generally inside, and the compressor outdoor unit outside, although the stainless steel cylinder can be located outside as well.

It works on the same principle as an air conditioner or a refrigerator, extracting ambient free energy from the atmosphere and transferring it into the refrigerant gas. This gas is compressed to a liquid in the heating coil inside the stainless steel hot water cylinder which creates energy and heats up the water.


The refrigerant pipe length (of up to 20 meters) between the outdoor unit and hot water cylinder gives you plenty of flexibility to place the outdoor unit out of sight.

The heating capacity of a heat pump hot water system is almost twice as much as a standard electric heater, meaning the recovery (reheat) time is twice as fast than a standard hot water cylinder.

The Calitec system is an intelligently controlled set-and-forget system. It provides a reliable hot water supply in any weather and any time of the day.


Designed specifically for New Zealand conditions, the Calitec system is built using high quality parts, and is designed to be eco friendly and long lasting. Our stainless steel hot water cylinders are fully insulated with 45mm Polyurethane Foam. We ensure they are built to last with a 20 year warranty, along with a 5 year warranty on the outdoor unit.
