Whole House and MVHR Heat Recovery

A Range of Whole House Multi Room Extractors and Complete Home Heat Recovery Units,

These Complete Home MVHR systems are designed to provide effective ventilation while minimising heat loss.
They work by extracting stale air from a room and replacing it with fresh air from outside. The main feature of a heat recovery system is that it captures the heat from the outgoing air and uses this to warm the incoming air. This process ensures that your home remains warm and comfortable without the need for excessive heating.
The systems are highly effective and can be installed in various rooms, including bedrooms, living rooms, and home offices, making it a ideal solution for any home.
Our Range of Whole House Multi Room Extractor Systems offer Whole house extraction from several rooms continually at a low rate to ensure good air quality.

Whole House Constant Extract fans multiple areas such as the MEV160 and MEV300 offer a simple extraction solution to multiple rooms at the same time,

Whole house ventilation systems ensure that condensation, and the damp and mould that inevitably follow it does not become a problem in your home. Air is gently moved around from a central location that removes moisture from the air along with other irritants and potentially harmful VOCs. Filtered air from outside contains none of the pollen that can cause Hayfever during summer months, meaning that whole house ventilation has additional advantages for people who suffer from allergies.

Modern whole house ventilation systems can include heat recovery (MVHR), which uses a heat exchange to recover the warmth from outgoing air to heat the fresh air coming into the building. These are highly efficient and help contribute to lower energy costs.
