Duoheat Pool & Domestic Hot Water Heat Pump: Pool up to 95m2
Description

The Duoheat range of dual-purpose heat pump water heaters eliminates the need to invest in two separate heat pumps. They are ideal for heating both users' pool and domestic hot water needs, reducing unit redundancies and minimising the overall footprint of your equipment.

These units are ideal for swimming pools with a surface area up to 95m² in the Coastal North Island (see “Scope” for further details). Typically, for every 1kW of electric input, users receive 5kW worth of heat.

Scope of Use

The heat pump most suited to each situation is determined by a number of factors. When combining the heating for a swimming pool and domestic hot water, sizing priority is given to the pool as it has the greatest load requirement. These factors include things such as; surface area of the pool, whether the pool has a cover and the time it is covered, and local temperature and weather conditions.

For more information about heat pump sizing please contact Hot Water Heat Pumps. As a general guide to heat pump requirements for an extended season of swimming from mid October to mid April as listed:
