In this blog, we will answer the question ‘What are the best MVHR systems?’

With new buildings being made to be as energy efficient as possible, and the UK aiming for 95% of its electricity usage to be low carbon by 2030, it is imperative to understand how we can make the most of our ventilation. This is where MVHR units come in.

To prevent mould, fresh air should constantly be introduced into your dwelling daily, as it helps to regulate temperature and reduce condensation. Introducing fresh air can be as simple as having a ventilation routine, or installing extractors or MVHR units. Almost all of this is facilitated by ducting.

I-Sells is here to provide the answers you need whilst also supplying you with all the information you need to combat mould and have a well-ventilated home.

MVHR systems – What are they?

MVHR is a term used in the HVAC industry, MVHR stands for ‘Mechanical Ventilation with Heat Recovery’. This is the technical term for what is generally known as heat recovery units, or heat recovery systems.

Heat recovery systems provide all the benefits of regular ventilation with the unique addition of being able to retain heat that would have been lost with regular ventilation. Heat recovery systems can come in single or multi-room applications.

The advantages of heat recovery systems are the following:

  • Holds all the benefits of an extractor, including the removal of stale air, humidity and smells.
  • It helps to prevent the cultivation of mould through the removal of humidity.
  • Temperature sensors ensure that additional heat is not being added to the atmosphere of the home if it is already hot.
  • Heat recovery systems take a lot of the burden from you conducting a ventilation routine. This is ideal for a vulnerable person.
  • Less of a need to use your central heating frequently as the heat generated through your house is recycled through the heat recovery unit.
  • The reduced use of heating as a result of the heat conservation granted by a heat recovery unit can help you save on energy bills.

What is the reason that ventilation is important?

Before we can talk about heat recovery ventilation, why is regular ventilation so significant?

Ventilation is critical in maintaining the health of your home, not to mention your own general health. This is because ventilation is the key factor in preventing humidity, condensation, and ultimately mould in your home.

Mould is a kind of fungus that grows and spreads in humid and damp environments. If left unattended, the spread of the mould can not only be an eyesore, but it can alter the air quality in your home, affect your health, and can weaken the structure of your home.

There are many types of mould, but upon noticing any kind of mould, you should work towards removing it through mould removal products, or employing a ventilation routine/using ventilation mechanisms.

What can cause mould?

As highlighted, mould can be caused by humidity and condensation that is left unattended. Here are a few factors that contribute to mould developing.

  • Not ventilating your home at all.
  • Not ventilating when cooking or bathing.
  • Leaks inside the home
  • Mould spreading from another area

How do MVHR systems work?

MVHR systems are generally located in the attic, or a room in your home, depending on the model you opt for. It works by extracting the humid air in your home (mainly in your kitchen or wet room/bathroom) the warmth from this humid air is extracted and mixed with the air that is extracted from outside.

In a nutshell, here’s what you get from MVHR systems

  • Extraction of humid air
  • Humid air is replaced with fresh air from outside but is also mixed with the warmth of the humid air that was extracted (without the moisture.)

Can the air that is used be cross-contaminated?

No, MHVR systems have multiple vents to prevent this.
