How we approach MVHR in Isleworth
MVHR works best in a home that is reasonably airtight: a new build, a deep retrofit with insulation and new windows, or a renovation where ceilings are coming down anyway. In a draughty older house it still ventilates well, but less of the heat-recovery benefit is felt because warm air escapes through gaps instead of the unit.
Radial semi-rigid ducting
One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.
Summer bypass and boost controls
Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.

Questions from Isleworth
How do I get a price for MVHR in Isleworth?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
How noisy is MVHR?
Correctly sized and balanced MVHR is very quiet on normal speed; most people stop noticing it within days. Noise problems usually come from undersized ducts or a unit running flat out, which is why we design the rates first.
Do I keep my trickle vents with MVHR?
No. Under Approved Document F, background ventilators should not be installed with a whole-home MVHR system, so we advise closing or removing them once the system is commissioned.
