"Insulation, insulation, insulation," has been our mantra to clients over many years, but now that highly insulated and airtight homes are becoming the norm, indoor air quality has become a prime concern. A building that cannot breathe will be subject to condensation in wet rooms, leading to mould and other nasties. Poor indoor air quality has led to a phenomenon that has come to be known as sick building syndrome. If the indoor air quality is poor, the inhabitants will also suffer breathing associated ailments, such as asthma. The forthcoming amendment to the building regulations is likely to tighten the requirements for ventilation. Opening a window will no longer suffice because it will defeat the purpose of having an energy efficient airtight building. Efficient ventilation without heat loss will be necessary, and the best way to achieve this is through MVHR.
MVHR
Mechanical ventilation with heat recovery draws warm, stale air from warm wet rooms like bathrooms and kitchens, and puts it through a heat exchanger. At the same time, fresh air is drawn into the building and is pre-warmed in the heat exchanger, then distributed through ducts in the ceiling or loft to rooms such as living rooms and bedrooms. The effect is a comfortable home that feels fresh and breathable all the time as it operates 24/7 irrespective of whether there is a need to improve air quality, but you can set up a user profile to vary the circulation rate depending on your lifestyle.
The systems we install use sensors to detect increases in CO2 and humidity. Being sensor driven makes the system more energy efficient because, thanks to its intelligent sensors, it will only ventilate when necessary.
BENEFITS
-
Energy Efficiency - MVHR recovers and reuses up to 95% of the waste heat within your property. All of the units we install are passibe house approved.
-
Controls Condensation - Prevents damp and mould growth to ultimately improve indoor air quality.
-
Alleviates Allergies & Asthma - As the incoming fresh air is filtered, allergy and asthma symptoms are reduced.
-
Tackles Unpleasant Odours - The fresh air from the MVHR system will tackle everyday strong odours, for example from cooking and pets.
-
Reduces Noise Pollution - Because the MVHR system is moving already warm fresh air around your home we take account of this when calculating the size of heat pump your home needs.
Installing any MVHR system can sometimes reduce the size of heat pump required.
