What is the best system for me?
There are various factors to consider when comparing MVHR systems.
Firstly, you should understand the technology used to determine whether MVHR is ideal for your property. For example, the structure of your building may not be suitable for installing an MVHR system. You’ll find that MVHR suits properties with a high degree of airtightness (new builds) so indoor air doesn’t just escape through cracks and poor insulated rooms. This is a massive waste of energy and money!
You’ll also need to consider your property location, as noise and air pollution offer different levels in different areas. (A UK pollution map will give you an idea of the pollution level in your area.) Determining your location and pollution levels will distinguish what type of filtration you need.
Another aspect to consider is which unit complies with the government building standards for the size of the property. This includes the size of the building, the number of rooms, wet rooms, and occupants.
Ducting is also critical. Ducting that is too small for the airflow rate will result in high resistance and velocity of air, creating noise issues. Semi-Rigid radial duct systems create less system pressure than traditional branch systems.
Other things to consider are accessibility to the unit for maintenance, how you want to control the system (apps or wall monitors) and any extras like CO2 monitors.
However, we’re only scratching the surface. We recommend you contact the team at Mid-Tech Services, and discover our other ventilation blogs for more information, as it’s paramount that an MVHR system is designed by a specialist and installed correctly by competent professionals.
