Some questions answered
What is MVHR?
MVHR stands for Mechanical Ventilation and Heat Recovery
MVHR mechanical ventilation with heat recovery uses a heat exchanger to recover the heat contained in air extracted from your kitchen and bathrooms to warm fresh air entering the house – this is then ducted to the living areas and bedrooms. A good system is capable of recovering over 90% of heat from the extracted air, reducing the burden on the heating system. Also known as heat recovery ventilation, it also reduces damp and condensation in the connected rooms (e.g. bathrooms, kitchens and utility rooms) and can help allergy and asthma sufferers.
Rose cottage is a Victorian, solid wall, detached building with poor insulation on the walls. The insulation deficit will be remedied as the house is renovated. The issue with solid walls is they are cold and in the winter attract condensation. And what does wet wall encourage, mold? We had a significant issue with mold in certain areas of the upstairs rooms which was not cured unless the heating was increased to uncomfortable and very expensive levels.
After some research we decided to add MVHR to all of the upstairs rooms. Extraction is from both bathrooms and fresh, warmed air is pumped into the bedrooms. The effectiveness of the installation is surprising, the damp and mold has all but gone. The air flow in all rooms cannot be heard on the background trickle setting and only just audible when then boost is activated. This happens when someone enters either of the bathrooms and is timed. The heating is also set to a realistic level both for comport and cost.
More advanced MVHR units than the one we fitted have humidistats which trigger a higher flow rate when the relative humidity in the extracted air exceeds a set value. The one at Rose cottage uses PIRs int he bathrooms to trigger the increase flow rate.
The problem of damp is not just limited to older properties. As buildings are improved and renovated the natural air leakage of the property is reduced which can lead to an increase in humidity. So mold and poor air quality is not just limited to older properties.
