Ensure Your Home is Well Ventilated with an MVHR System

Ensuring your home is well ventilated is vital for a healthy home. In fact, failing to do so can lead to issues with mould and condensation, which are not only unsightly – and a pain to treat – but can also lead to a range of health issues like asthma.

Ventilation helps to remove stale air from the inside of your home and replenish it with fresh air from the outside. This is done through both uncontrolled ventilation, and controlled ventilation – such as with an MVHR system. We are going to look at these two methods in this article, and explain why an MVHR system is a good choice.

Uncontrolled Ventilation

Uncontrolled ventilation is something that is installed when a property is first built. The most common forms of uncontrolled ventilation are trickle vents and airbricks, as both comply with building regulations and are cheap to install. However, while they are useful in some situations, they do have some negative points, including:

* Trickle vents need to be permanently left in an ‘open’ position to provide adequate ventilation.

* Internal doors need to be kept open to allow air to move through the home.

* Airbricks can, over time, get blocked by debris, dirt and vegetation located outside the home. Inside the home, furniture and curtains can block them.

* Ventilation depends on the wind. When it’s blowing hard, the home can become ‘over-ventilated’, and when it’s not blowing at all, there won’t be any ventilation.

* Uncontrolled ventilation can lead to odours and moist air spreading around the home. This can lead to mould and dust mites being spread, and can even impact the integrity of building materials.

Controlled Ventilation

Controlled ventilation is when an activated ventilation system is installed in the property in order to automatically move air around. These tend to be the better option as they don’t rely on outside influences, and don’t have the same requirements as uncontrolled systems in order to work as intended.

BPC Ventilation units are one of the best examples of this, and they’ve become incredibly popular with those self-building their homes over the past decade. MVHR systems ensure your home maintains a healthy air environment while also ensuring no heat is lost from the property. It is because of this that they are both environmentally friendly, and more useful for homeowners who live in moderate and cold climates. Homes do, however, need to be suitably airtight in order for an MVHR system to work as intended.

In addition to the benefits described above, MVHR systems are also more useful than uncontrolled ventilation systems for those with allergies, as they can help to remove airborne allergens such as mould spores and pollen. This makes them a top choice for allergy sufferers. That said, it must be pointed out that it can be hard to install an MVHR system into an existing property. It’s best to speak to a professional to see if it can be done.

Ventilation is something that many homeowners these days are concerned about, and MVHR systems could be the ideal solution.
