Install MEV

Mechanical Extract Ventilation (MEV) is a system where a central extract unit is mounted in a loft or cupboard and ducted to extract polluted air from the wet rooms of the house. As there is no heat recovery, there is no requirement for any ducts to supply the replacement air.

Install Supply Ventilation

A Supply Ventilation system uses fans and ducts to supply fresh air into a home and allows pressure build up in the home to natually ventilate or exhaust the air out of vents, so only has one fan and duct system.

Install Balanced Ventilation

Balanced Ventilation supplies and exhausts approximately equal quantities of fresh outside air and polluted inside air. A balanced ventilation system usually has two fans and two duct systems.

Install MVHR

MVHR (Mechanical Ventilation with Heat Recovery) is a whole house ventilation system that both supplies and extracts air throughout a property whilst retaining most of the energy that has already been used in heating the building.
