External Heat Exchanger for Pools

Mitsubishi Electric Hot Water Heat Pumps are designed to both heat or cool water. You can choose from: 8.0kW, 11.2kW, 14.0kW or 16.0kW of heating - suitable swimming pools.

The PUHZ-RP split system requires an external heat exchanger. The flexibility of this system allows the installer to position the heat exchanger right where the hot water is required for both new and retro-fit installations. Vaportec HXTi with high density plastics and a titanium coil heat exchanger for swimming and spa pool heating will require mounting and installation of refrigerant pipe work to the PUHZ-RP outdoor unit. The system is controlled by the PAR-W21 LCD wall 7 day timer/controller and an advanced PAC-IF031 interface for multiple use applications.

Note: Ancillary equipment such as water pumps and expansion tanks are to be provided separately by the installer, and selected to meet the individual system pressure and flow requirements. This system is supplied with the Vaportec HXTi Heat Exchanger.

Selection Guide

Use this guide to estimate your heating requirements, however units should not be purchased without advice from your heating or pool specialist. Every application is as individual as its owner. An incorrect selection may lead to unnecessary power consumption or a system with insufficient heating capability.

Spa Pools

We have a new Titanium Coil/PVC Shell heat exchanger to effectively heat where aggressive chemical treatment is present. This is matched to one of our PUHZ-RP Hot Water Heat Pump units. Alternatively use our PUHZ-W50 with an intermediate water to water heat exchanger.

Swimming Pools

Hot Water Heat Pumps enable outdoor swimming pools to be heated to a comfortable temperature to extend their use year round. Indoor pools also benefit from heating because they don’t receive the same solar gain as outdoor pools in the summer, and can be heated during winter to provide year round swimming. The heat pump size required depends on environmental aspects of the pool, including location and construction, temperature of the pool, and the air temperature. The most important factor is the pool water surface area as this is where heat is lost through evaporation. Installing a pool cover is the best way to retain this heat.

Due to the large number of variables, a simple calculation of heat pump capacity is not always possible. We recommend you check our website or contact a competent installer to have your pool heating requirement carefully assessed.
