Mechanical Ventilation with Heat Recovery (MVHR)
SHB Offer a full range of MVHR installation and maintenance services.
What Is MVHR?
Mechanical Ventilation with Heat Recovery (MVHR) is a modern system of ventilation. MVHR systems extract stale, moist air from the inside of the house, harvest the warmth from it and use that to heat clean, cool, filtered air brought in from outside.
This system is more efficient than traditional forms of heating and air filtering because conventional methods lose heat from the home to the air outside. This system also helps to eliminate condensation inside a home.
How Does MVHR Work?
1) Stale, dirty and moist air is extracted from the rooms of the house via unobtrusive ceiling or wall mounted louvred vents.
2) The extracted air is ducted through the heat recovery unit’s counter flow heat exchanger which removes heat from the air before it leaves the house through external vents.
3) Cool fresh air is brought into the house, filtered and then warmed using the water heater coil which transferred the heat recovered from the discharged air. An electrical heater adds additional heat as required to maintain a pleasant air temperature.
4) The warm, purified air is then ducted back through the house to the rooms in use and is quietly delivered through ceiling or wall supply registers, adjustable, louvred vents.
This air then makes its way through the 75mm anti static radial ducting system, directly back to extract plenum box by directly connecting each inlet/outlet there is zero leakage from there then back to the heat recovery unit via galvanised rigid ducting. Before being discharged outside, it passes through the counter flow heat exchanger giving up its heat to the cold fresh air coming into the house.
Why Use MVHR?
