How does MVHR work
In wet rooms, such as kitchens, bathrooms, W.C’s and utility rooms, extract points are installed to remove the warm, moist air. The air that has been extracted, before it is exhausted to outside, it is used to temper the incoming air into the building via a heat-exchange block within the unit. The fresh, filtered, pre-warmed air is then supplied into the habitable rooms such as the bedrooms and living room. The heat exchanger can transfer up to 92% of the heat recovered into the fresh incoming air.
How are the ventilation rates calculated?
Typically, the minimum ventilation rate is calculated by multiplying the total internal floor area by 0.3 l/s/m². The boost rate is calculated by assigning the following vent rates to each wet-room, and then adding them together. (kitchen 13l/s, bathroom 8l/s, utility 8l/s, WC 6l/s)
What to do if my home gets too warm?
During the summer months, there is a summer bypass system. This means that the intake air will not be tempered as it is diverted around the heat exchange block. This can help in reducing the indoor temperature.
How will it work with my heating system?
MVHR systems are designed to ventilate your home; it does not actually heat your home. The two operate completely independently. However, the benefit is that you do not lose the heat you’ve paid to be generated like you would with a standard ventilation system, as the MVHR system will recover up to 95% of this heat energy
Is much maintenance needed
There is very little maintenance with our MVHR units. We recommend that you check your unit filters annually. The filters can either be cleaned or replaced. However, this will depend on the environment in which you live and how clean the air in your home is.
How is the system controlled
The minimum requirement for controlling the MVHR system would be to have a manual boost switch for each wet-room. But the unit can also be controlled via humidistats, PIR sensors and wireless switches.
How is the system controlled
The majority of Nuaire MVHR units have a payback period of 7-10 years. This can vary depending on factors such as environmental factors and air tightness of your home. Nuaire’s MVHR units run on an average of 15p per day.
