What is Mechanical Heat Recovery Ventilation and Why Should You Consider it?



Proper indoor ventilation is gaining attention at the moment, and so is energy conservation. MVHR, or mechanical heat recovery ventilation, tackles both of these issues. Simply put, it’s a system that allows air that is being pulled into a building to be conditioned by air that is being pushed out. It’s estimated that you could reduce your energy costs by as much as 50% by using this kind of system. If this is your first time learning about MVHR as a solution, let’s take a look at how these units work and why you might want to consider them for your home.



How Do MVHR Units Work, Exactly?

MVHR systems are usually composed of an intricate system of ducts, filters, fans, and an air exchanger. The air exchanger is where all the magic happens. Air that is coming in is mixed with air that is expelled. This means that air that has been cooled down in the summer can be used to temper air coming in and hot air can be used to heat cool air coming in in the winter.

This has the effect of reducing the strain on your air conditioning and heating. This means that you'll not only be able to make savings and reduce your carbon footprint but extend the longevity of your system.

What are the Benefits of Getting One?

Besides the savings and environmental benefits, there are many other reasons why getting an MVHR unit might be a good idea. One of them is that you’ll be able to significantly improve the quality of air overnight. If you’re dealing with mould issues or have too much humidity in the house, an MVHR will allow you to have better control over it.

You’ll also notice how much fresher the air is instantly. These ventilation systems do a great job at expelling particles from the house and preventing allergens from proliferating.

There are also many side benefits to MVHR units, like more increased home security, for instance. With these systems, there is absolutely no reason for you to open a window ever again, which limits entryways for intruders.

Are They for Everyone?

Depending on your home, you may not be able to install an MVHR system, or it might be prohibitively expensive. If you want to keep the costs low, however, we would suggest you check out online providers such as BPC Ventilation. Services like these will also help with installation.

For these systems to be installed, the house has to meet certain airtightness requirements. This means that they are usually a better fit for more recent homes or new builds. However, this doesn’t mean that they can’t be installed if you have an older home. All you need to do is call a supplier to come in for an assessment. Many of them will also do it free of charge.

If you have never considered installing an MVHR system, or weren’t aware of how they work, we hope we were able to pique your curiosity. We strongly suggest you speak with an expert today if you’re interested and ask them as many questions as you can about how they might benefit you.
