Heat Recovery MVHR
Heat recovery is a process of continuously preheating the incoming cool supply air, by warming it with the outgoing exhaust air. A Mechanical Heat Recovery Ventilation (MHRV) system, offers greater energy efficiency, by bringing fresh air into all habitable areas, without letting the heat escape. Stale air contaminated with humidity, toxins and smells, is extracted from grilles in toilets and wet rooms. By continuously supplying preheated air into living areas, and extracting contaminated air from wet rooms, you create a whole house ventilation system. With the high standard of insulation and air tightness in the modern new build, there is an increasing requirement for the use of mechanical ventilation and heat recovery systems.
MVHR will give you a warm well-ventilated home, help save on heating, reduce the need for air conditioning, and eliminate excess moisture It keeps the interior ‘climate’ at a constant level, and helps retain up to 90% of heat.
Due to the air-tightness required with modern building regulations, some form of mechanical ventilation is essential. A MVHR system not only solves this issue, but also increases the heating efficiency of the home. It also increases the efficiency of a heat pump systems, as well as greatly reducing heating systems running costs.
Most excitingly a heat recovery system enables the modern self-builder to look at heating systems in totally different way, similar to that of a truly passive house.
“A heat recovery system makes heating a home without a traditional wet heating system possible”.
A heat recovery system, combined with a log fire, as well as the passive heat of a modern eco home, means that it is potentially possible to design a house without the need for a traditional and expensive ‘wet’ heating circuit.
Rather than radiators, or an under floor heating system, distributing heat from a boiler throughout the home, the MVHR system can distribute the heat from a simple yet efficient modern log fire.
Totally renewable, low fuel cost, and without the investment cost of the wet heating circuit.
