How an MVHR System Works
An MVHR system is one central unit, usually in the attic, a utility room or a hot press, connected by ducts to every habitable room. It runs continuously at a low, quiet speed.
- Extract: warm, moist air is drawn out of the kitchen, bathrooms, en suites and utility room, where the steam and smells are made.
- Supply: fresh outside air is filtered and delivered to the bedrooms and living rooms.
- Heat recovery: the two air streams pass through a heat exchanger without mixing, so most of the warmth in the outgoing air is passed to the incoming air.
- Boost: the system speeds up when a shower or cooking adds moisture, then settles back.
The result is a house that is aired all day and night without opening windows, without draughts, and without throwing away the heat you paid for. In an airtight modern home it is the system that keeps condensation and mould away.
MVHR in a new build or an existing home
In a new build the unit position, duct routes and terminals are planned on the drawings before the walls go up, which is the cheapest and neatest way to do it. In an existing home we route the ducts through the attic and ceiling voids, or fit single room heat recovery units where whole house ducting is not practical.
MVHR compared with the alternatives
MEV (mechanical extract ventilation) extracts from the wet rooms and lets fresh air in through vents, with no heat recovery; it costs less to install and more to heat. PIV (positive input ventilation) pushes air from the loft into the house and suits some older homes, but it does not recover heat from the air leaving the house. Single room heat recovery units bring the MVHR principle to one room at a time. For an airtight home, MVHR installation is the option that ventilates every room and keeps the heat; our comparison of MVHR and PIV goes into more detail.

Our MVHR Installation Process
- Free preliminary quote. You send floor plans or photos with your Eircode; we reply by email with a price range and our notes.
- Survey and design. We confirm the unit position, the duct routes, the valve in each room and the outside terminals, and size the system to the house.
- Installation. Unit, ductwork, valves, terminals and controls. A planned retrofit of two systems has taken three days.
- Commissioning. We set and measure the airflow at every valve and balance supply against extract, so the system does what it was designed to do.
- Handover and annual service. You get the measured figures and a walk through the controls and filters. The annual VentSolve service keeps the 5 year warranty valid.
One customer who had two MVHR systems installed by us wrote in a Google review: “They were extremely responsive from the first enquiry, and completed the full installation efficiently over just three days. The workmanship was excellent throughout and everything was finished to a very high standard. Their pricing was also very competitive compared to others I had contacted.”

Looking after your MVHR system
An MVHR system needs little attention, but it does need it regularly. The filters are cleaned or replaced so the airflow stays as designed, the condensate drain is checked, and once a year the unit, the fans and the flows at the valves are checked. Our annual MVHR service covers all of this and keeps the 5 year warranty valid. Signs that a system needs attention are covered in our article on five signs your MVHR needs maintenance.
