Description
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.
Application Examples
- New Build UK homes
- Cafes and Restaurants
- Dental / Doctor’s Surgeries
