Home ventilation systems

Home ventilation systems use fans to move air into your house, offering an alternative to opening doors and windows.

Types of home ventilation systems

There are two main types of home ventilation systems:

 Positive pressure ventilation systems

 Balanced pressure heat recovery systems

Benefits of home ventilation systems

A well designed and installed home ventilation system offers the convenience of good ventilation by continuously replacing air, independently of weather conditions.

If dampness is your main concern, address the source of the moisture problem before looking at ventilation systems. You will often be able to address the source of the moisture yourself without having to invest in an expensive ventilation system.

Ventilation systems by themselves are not an effective way to heat your home. If you are trying to make your home warmer, it’s better to invest in insulation and install an effective heating system.

Heat transfer systems

Heat transfer systems take heated air from one room of your house and blow it through ducts into one or more other rooms of your house. The source room must have a heater that can generate enough heat for multiple rooms, such as a large woodburner. Heat transfer systems do not normally bring fresh air into the house and as such are not ventilation systems. However, some ventilation systems may be combined with a heat transfer system.
