Ecodan 4kW Monobloc With Thermal Store

The packaged hydrobox offers a highly adaptable heating solution for retrofit or new build.
Designed specifically by Mitsubishi Electric to integrate with the Ecodan monobloc air source heat pump range and a third party cylinder, the hydrobox provides hydraulic components with an advanced simplified graphical user interface and controls. Fast commissioning via an SD card and energy monitoring functions
are now included.

The Ecodan QUHZ-W40VA is the ideal solution for new build homes
where strict building regulations drive down the space heating
demand, making the production of hot water the dominant load.
The Ecodan QUHZ operates with a market leading low noise output
and built in energy monitoring as standard. The thermal store has
been specifically designed to work with this system, giving high
hot water output without the need to pasteurise the water.
