An all-in-one system for space heating and potable hot water or as a standalone potable hot water system, the QUHZ is ideal for residential homes requiring domestic hot water heating as well as space heating through:

• Radiator Heating
• Underfloor Heating
• Fan Coils

The 5kw heating capacity lends its self to townhouses, apartments, passive houses or renovations looking for heating in a low energy loss building.

Consisting of an indoor thermal store and outdoor unit, the systems integration must be considered at the design phase so the unit can be installed and space is left to ensure the entire hydronic system can be installed with minimal impact to the home's function and aesthetic.

The QUHZ CO₂ Hot Water Heat Pump can also be installed as Domestic Hot Water (DHW) only, providing temperatures up to 70°C and can be retrofitted to an existing home.

It is recommended heat load calculations are completed to ensure system has adequate capacity for the installation (for other capacity options see the Ecodan Hot Water Heat Pump range). Mitsubishi Electric has a team ready to assist with calculations and design plans.

The product is not intended for large scale commercial heating application. Please refer to the Mitsubishi Electric QAHV CO₂ Hot Water Heat Pump for commercial potable hot water application.
