Heat Recovery Ventilation is becoming standard in all new builds with the higher Building Regs 2013. Every building needs a fresh air supply to maintain a healthy house and this can be achieved by the following methods:

• 4" hole in the wall
• Trickle vents in the windows
• Thermal heat recovery ventilation

With the heat recovery unit, it uses the wet extract air from the bathrooms and kitchen to preheat the fresh air from outside to the bedrooms, living and dining areas. The unit uses a highly efficient counter flow heat exchanger.
