Creating a healthy living environment
The fundamental part of the entire system is a high efficiency counter-flow heat exchanger (3). This heat exchanger transfers up to 90% of the heat from the extracted “wet areas” air (2) to the incoming fresh air (1). The principle behind a HRV system is to change the air continuously in your home and use the recovered heat from the extract air to warm the incoming air. Extract points are located in wet areas such as bathrooms, kitchen, utility and WC. Supply points are in areas such as bedrooms, living and dining rooms
Increased comfort and reduced heating bills
The HRV system provides a constant supply of fresh air to the house, while simultaneously removing moisture at source in wet areas. Increased comfort and reduced heating bills result.
Houses need to be well sealed for a HRV system to be efficient. Consideration also needs to be given to the type of fireplace fitted. Idealy a room sealed stove with externally supplied independent air supply is required to ensure maximum efficiency of the HRV unit and eliminate possible downdrafts in the chimney as a result of the HRV system.
The size and volume of your home will determine what type of HRV unit will need to be installed. Larger homes may even need more that one unit to achieve optimum air changes.
This is how a HRV system works
