Are MVHR Units Worth it?

Written by ATSPACE | Aug 10, 2022 1:36:22 PM

If you’re building a new home or renovating a property, then you may have considered installing an MVHR system. These systems are designed to supply your home with fresh air, while simultaneously recovering heat from wet rooms, such as kitchens and bathrooms, which is usually lost and wasted. This helps save energy, as well as money on bills, and helps create a healthy living environment.  

But with all this said, is it the right fit for your home?  

There is no doubt that these systems offer significant savings on heating bills over the traditional extractor fan installed in wet rooms, as well as window vents. But by far the stand out factor of this system is the dramatic improvement of lifestyle. The system helps improve the indoor air quality of the home, which increases wellbeing and health. 

Lowering your heating costs 

Depending on the system installed, it could reduce your heating requirements by up to 25%, as well as recover up to 90% of the lost heat. This means your initial investment could be paid back within 5 years.  

But this all depends on other factors that the property must achieve to hit these kinds of numbers. The biggest one is the air tightness. What is airtightness? ATSPACE offers this service, as well as blogs to explain more about it.  

Indoor Air Quality (IAQ) 

The last decade has seen a rapid growth of well insulated buildings. Unfortunately, houses that are well insulated and poorly ventilated are likely to have poor air quality. This can lead to damp, condensation, mould and dust in the dwelling. It can also cause foul smells and a build-up of VOC’s (Volatile Organic Compounds) in the home, which will also lead to health issues like asthma and other respiratory problems.
