MVHR's - what are they?

MVHR stands for "Mechanical Ventilation with Heat Recovery." It is a type of ventilation system that is used to provide fresh air to a building while also reducing energy loss.

MVHR systems work by drawing in fresh air from the outside and passing it through a heat exchanger. The heat exchanger captures the heat from the outgoing air and transfers it to the incoming air, warming it up before it is distributed throughout the building. This process helps to maintain a comfortable indoor temperature, and humidity, while also reducing energy loss.

MVHR systems can be used in both new and existing buildings. They are particularly useful in buildings that are airtight and energy efficient, as they can help to maintain good indoor air quality without compromising the building's energy performance.

There are two main types of MVHR systems: decentralised and central. Decentralised systems have a unit installed in each room, while central systems have a single unit that serves the entire building.

MVHR systems are a cost-effective and energy efficient way to provide fresh air to a building, as they help to reduce energy loss, maintain a comfortable indoor environment and minimise odours. They are also low maintenance and easy to operate, making them a popular choice for many homeowners and building owners.
