The principles of MVHR
As houses modern houses are constructed with stricter air tightness levels it’s become critical to consider how adequate ventilation is planned into each build.
Mechanical Ventilation with Heat Recovery (MVHR) mechanically supplies and extracts air, recovering heat from outgoing stale air and using it to warm up incoming fresh air. This can greatly improve indoor air quality and energy efficiency.
MVHR systems can help to maintain a comfortable indoor climate, reduce energy costs, and improve indoor air quality by ensuring a continuous supply of fresh air. They are particularly beneficial in tightly sealed properties where traditional ventilation options are limited.
“Your professionalism, quality of work and genuine care about what you do has made the whole process easy from start to finish. I would be more than happy, and fully intend to recommend EnergyMyWay to anyone who is considering renewable energy for their property."
Andrew Brown, customer
What does it look like?
The main component of an MVHR system is a central unit with a fan and heat exchanger. This can be located in the house or loft space.
A pair of ducts run from the unit to external vents, either in a wall or through the roof. One vent draws fresh cold air into the central unit, the other extracts stale air from the house.
Adjacent to the MVHR unit there is a supply and extract manifold, individual ducts (normally either 75mm or 90mm in diameter) run from the MVHR unit to a discrete ceiling vent each room in the house.
The vents in the hot, wet rooms, such as the bathrooms, kitchen and utility room continuously extract, whilst the ceiling vents in the bedrooms and living rooms supply fresh warmed air.
Use MVHR to provide cooling in hot weather
One of the challenges with modern homes is that high insulation levels mean it can be a challenge to keep them cool in hot weather.
The MVHR system has a summer-bypass, so the extracted air bypasses the heat exchanger, ensuring that the hot air removed from the house. However, mechanical cooling can be added to the system, so the incoming air can be cooled to reduce the incoming air temperature in to the house.
This is not air conditioning, it’s comfort cooling, but we have found clients have enjoyed the benefit of this function in the very hot summers.
“We worked closely with EnergyMyWay over a about a year as we renovated our town house to become more green and reduce our dependency on fossil fuels and the grid. They installed Solar PV, Air Source Heat Pump, Mechanical Ventilation with Heat Recovery, and home automation systems. They were utterly professional throughout the process keeping us informed of progress, tasks that needed input from us, milestones coming up, etc. They responded in a timely manner via both email and telephone and several times popped over to help out in-person. We have recommended them to many friends and neighbours and remain in contact over 18 months on.”

You can breathe easy
An MVHR system helps to improve indoor air quality by removing pollutants, allergens, and other harmful particles that can lead to health problems.
One of the many benefits of an MVHR system is for those people who suffer from allergies, as we can fit anti-allergy filters in the unit which reduce the level of particles entering the house which trigger reaction for those suffering from asthma and allergies.

MVHR systems are installed by our EnergyMyWay installation team of directly employed operatives, all of whom are qualified under the BPEC Domestic Ventilation training scheme.
