Windsor MVHR Whole House Heat Recovery Units, DC or AC

MVHR is a whole dwelling ventilation system that supplies & extracts air continuously at a low rate with the facility to be boosted as required meeting Part F System 4. 

The unit is normally installed in the loft space or cupboard and rigid ducting supplies fresh filtered air to the habitable rooms and extracts stale polluted air from the ‘wet rooms.  Supply and extract diffusers are fitted to the ceilings and can be adjusted so as to balance the system.  The unit incorporates a polymer heat exchanger that tempers the incoming air before it is delivered to the habitable rooms.  The efficiency of the exchanger can vary from 70% to 95% heat recovery. Background ventilators in windows are not required.

The system can be controlled to boost speed either;
- Manually via single or multiple switches
- Automatically, typically via humidity or other sensors, these should be located in or near the wet rooms.
