How we do it

Insulated ducts carry extract air from the wet rooms and supply air to the habitable rooms. Inside the unit the two airflows pass each other across a heat exchanger without mixing, so the incoming fresh air picks up heat from the outgoing air. Filters on both sides keep pollen and dust out of the house and keep the exchanger clean.

New build or full renovation

Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.

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 about MVHR installation in Dumfries and Galloway

Which rules apply to ventilation in Dumfries and Galloway?

In Scotland, ventilation is covered by section 3 of the Building Standards Technical Handbooks. Private rented homes must meet the Repairing Standard, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.

Is MVHR worth it in an older house?

It can be, but the payback is best in a home that is fairly airtight. In a draughty house MVHR still gives steady fresh air and condensation control, but a PIV unit or continuous extract fans may solve the same problem for far less. We will tell you which on survey.

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.
