Mechanical ventilation with heat recovery is a technology that could potentially change the world. Not only are these systems instrumental in curbing carbon emissions, but they could also help reduce the spread of pathogens in poorly ventilated buildings. 

There are still many myths surrounding these systems that might be causing confusion when it comes to installing them, however. Here are some of the most common myths and misconceptions about MVHR technology.

They Can Be Installed in Any Home

Not only is this untrue, but it’s a myth that could end up costing you a lot of money. Someone may try to sell you on these systems knowing that your home is not the proper fit for them. In reality, MVHR systems only work if the home is air-tight up to a certain level. This is why older homes are not usually suitable candidates, and you can’t really retrofit to make the house airtight enough in most cases.

This means that you might have to think about another option if you own a period home. If the house is fairly recent, chances are it meets airtightness standards. An inspector will be able to make sure that everything is okay before you go through with it. 

You Can’t Open Your Windows

Another common misconception about MVHR systems is that you can’t open your windows when using them. This myth probably comes from air conditioning and heating that actively heats or cools the air. When you open the window, these systems have to work harder to maintain the temperature.

MVHR passively conditions or heats the air that is coming in, so there’s no difference. In the summer, you can open the windows and turn the MVHR down. In the winter, however, it would be a better option to keep the windows closed to retain heat.

All Systems are Roughly the Same

Not true. The type of system will affect everything from the price, installation, and how long it will last. It will also affect how easy it is to find parts for it and service. This is why you need to make sure that you buy your system from a reputable team with a wide selection of units and parts. BPCventilation.com is a perfect example. Services like these will be able to install, maintain, and also inform you of the different options available to you.

MVHR Systems Cost a Fortune to Run

A lot of people may also be under the impression that the energy that it takes to power an MVHR system will negate any type of energy savings that they can make. But, in reality, a 3-bedroom system will use about 25-40W per hour. That’s a minuscule £26-£50 per year. Compare this with the roughly 30% in energy savings that you stand to make, and it becomes a no-brainer.

So, if you were entertaining any of those myths, we would suggest that you consult with an expert today. They’ll be able to explain the ins and outs of the systems and help you decide if they could benefit you.
