Are Heat Recovery Systems Worth It?

With household energy bills increasing by over 50% in 2022, people are now assessing options to invest in appliances that limit the need for excessive heating. This is followed by the UK aiming for 95% of its electricity usage to be low carbon by 2030.

I-Sells is here to show you the appliance you can invest in, that will help you reduce your energy bills, keep you warm and protect you from mould. This is done through a heat recovery unit.

In this article, we will address the question ‘Are heat recovery systems worth it? Whilst also share with you the benefits this technology can offer.

What is a heat recovery system?

A Heat recovery unit is a form of ventilation that facilitates the process of heat recovery ventilation (HRV). This is the process of extracting indoor stale or moist air and replacing it with filtered fresh air from outside, whilst recycling the warmth from the air it was replacing.

As of 2022 England and Wales scored a D in the latest stats for energy efficiency. (With A being the best and E being the least energy efficient).

From this, it is clear to see we still need some help with recycling heat and making the most of our energy. With a heat recovery unit, you get the benefits of ventilation whilst also making your home more energy efficient & also free from mould and condensation, which in turn will save money on energy bills and help to protect your health.

How does a heat recovery system work?

A heat recovery unit facilitates the removal of indoor humid or stale air and replaces it with fresh outdoor air which is also heated by recycling the heat from the indoor extracted air. Along with this, they have the ability to reduce the buildup of condensation, making your home or business less susceptible to mould.

The recycling of heat makes them more energy efficient and a good long-term investment to help you save on your energy bills.

Benefits of a heat recovery system

Here are some benefits of having a heat recovery system:

  • 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 recycling of indoor air without removal keeps the air fresh without having to lose any heat which is vital, especially in winter.
  • Helps to create an environment not fit for mould and condensation
  • 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.

Why is ventilation important in the first place?

Heat recovery systems build from the process of ventilation, but why is ventilation important in the first place? Ventilation helps to prevent humidity and condensation, which if left unattended becomes the perfect environment for mould to develop.

Condensation occurs when heat and moisture in the air is confined to a certain area, as this heat tries and fails to escape, droplets of water are created on cold surfaces. A good way to think about this is having a hot shower on a cold day and not opening your window.

The reason condensation creates mould is that a damp and humid environment is the optimum condition for mould to grow in. In regards to windows, it is a big problem if there is mould on your windows (it can usually be found in the corners of the windowpane or the walls connected to the window).

The reasoning is that mould particles can travel through the air without us seeing it, incidentally, this means opening a window with mould on it runs the risk of that mould being blown inside your room alongside the fresh air.

That being said, condensation is not the only cause of mould, it can occur from leaks in the structure of a building too.

Ventilation

Whether you choose an extractor fan, or a heat recovery system, our range can help to create a mould-free environment by addressing humidity and condensation. However, mould can still be a problem if you don’t have a ventilation routine, which can just be as simple as opening the window when showering, or using an extractor fan/opening a window whilst cooking.
