The result of this is that your home will have a constant supply of fresh air, lower heating costs, no condensation and increased comfort levels throughout your house.
In order for the system to work efficiently your home should be well insulated and have a level of air tightness that would be lower than 5m3/m2/per hour. This will ensure that there will be minimum heat loss and minimum infiltration of air that has not passed through the heat exchanger.
The unit that will be required for your home will be determined by the size and volume of your house. Some houses will require more than one unit to ensure that sufficient air changes are achieved and a comfortable and healthy environment is guaranteed.
The basic principle of a Hrv system is to continuously change the air within your home. This is achieved by extracting stale moist air from all wet areas, such as bathrooms kitchen utility and wc areas, and using the recovered heat from this air to warm the fresh incoming air.
The air is then supplied to all living areas such as bedrooms, living and dining rooms.
The fundamental part of the entire system is a high efficiency counter flow heat exchanger which exchanges up to 90% of the heat from the extracted wet areas to the incoming fresh air from outside.
