4 Things People Often Get Wrong About MVHR Systems


MVHR systems use fans and air exchangers to prevent energy waste and allow homeowners to make energy savings while reducing their carbon footprint. Many people are curious about these systems, but common misconceptions often stop them from getting one. It would be a shame to let myths and half-truths prevent you from enjoying all the benefits of these wonderful systems. Let’s take a look at some of the things people often get wrong about MVHR systems.

The Energy Savings are Overrated

That’s wrong. You can make very real savings with this type of system, but those savings will indeed depend on the household.

In most cases, people can expect to save from 25% to 50% on their energy costs by switching to MVHR. The way your home is ventilated, how much you use heating and air conditioning, air tightness, and a myriad of other factors will influence how much you will save. If everything is optimal, then you can expect to make some impressive savings with your system even after using heaters.

It Prohibitively Costly

We’re not going to lie and say that MVHR systems are cheap, but they aren’t all that expensive either. If you live in a 2-bedroom home, then you could get a good system for around £3,500. This isn’t that much when considering that you’ll be able to recoup these costs both with energy savings and a higher perceived value on the property.

How much you pay will largely depend on the contractor as well. If you’re looking for a trustworthy contractor that offers reasonable quotes, then is a good place to start.

You Can’t Open Windows when You Use MVHR

Another thing we often hear is that you can’t open your windows when you use MVHR systems. Indeed, you won’t have to open your windows ever again if you have a working system, but that doesn’t mean that you’re obligated to keep them closed. So, you’ll be free to leave your windows open in the summer if you want to cool or ventilate your house naturally unless you have a hot tub on the deck to relax.

MVHR Systems are Noisy

MVHR systems will generate noise like any other type of ventilation system, but the sound will be barely noticeable if they’re installed and maintained properly. This will also depend on the strength of the system in question.

This is why your choice of contractor is very important. They can take extra precautions to make sure that noise is not an issue if you ask them. A bad contractor, on the other hand, might do everything wrong and produce a very noisy system. So be careful with who you let in your home and vet every constructor thoroughly.

Now that you know a bit more about MVHR systems, you can start speaking with a few professionals and see what these systems are truly about. They have so many things to offer, so inform yourself about them as much as possible and seek opinions from as many experts and non-experts as you can.
