MVHR SYSTEM IN OLD HOME

I’m planning to install an MVHR system in a renovation project and wondering how effective it really is in older UK homes.
Does it make a noticeable difference in air quality and heat retention, especially if the property isn’t perfectly airtight? Also, how complex is the installation compared to new builds — is it worth the effort and cost in a retrofit situation?

Hi,

My uncle had MVHR installed during the renovation of an older house and from what he told me, the biggest difference is in everyday comfort 🙂 The air feels fresher, there’s much less moisture building up on the windows, and overall the house just feels nicer to live in, especially during winter.

He also said that this kind of system makes the most sense when the house is already well insulated and reasonably airtight. Otherwise, part of the benefit is simply lost.

The biggest downside during the renovation was aparently the installation itself, because you need to find places to hide all the ventilation ducts and plan everything properly. It’s definitely much easier in a new build.

Overall though, he doesn’t regret it at all and said if he was renovating again, he’d still choose MVHR.

Hi,
I’m not an expert, but when I was looking into MVHR myself, I often came across comments saying that one of the biggest advantages is not having to open windows as often to keep the house ventilated. The air is constantly being refreshed, which makes the indoor environment feel more comfortable, especially during winter.

I also think it depends on the scale of the renovation. If you’re already carrying out major refurbishment work, adding MVHR could make a lot of sense. On the other hand, installing it in a fully finished home can be more complicated and expensive.

If I were renovating an older property and planning to improve the insulation, I would definitely consider an MVHR system. That said, I’d first speak with a professional to assess whether the building could take full advantage of what the system offers.

Hi,

In my opinion, if you’re already planning a major renovation and improving the insulation, it’s worth at least considering MVHR. From what I’ve read, most people appreciate the constant supply of fresh air and the improved day-to-day comfort. The key is making sure the system is properly designed and installed.
