What Are the Different Types of Heat Recovery Systems?

Heat recovery systems are an extremely helpful tool in regulating the air temperature of your home, as well as its cleanliness pollutants such as dust and other allergens. Not to mention the removal of humidity, which can result in condensation that can eventually become mould.

In this blog we will answer the question, what are the different types of heat recovery 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 heat recovery systems 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 heat recovery systems. 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.

Heat recovery systems explained

A heat recovery system has the benefit of keeping your home energy efficient and warm, whilst maintaining ventilation. Heat recovery systems vary in size, some can be made just for a singular room, whilst others are made for your whole home.

The aim of a heat recovery system, aside from recovering any heat that is lost through ventilation, is to create an environment in which condensation, and consequently mould can’t survive in.

The advantages of heat recovery systems are the following:

  • Holds all the benefits of an extractor, this includes removal of stale air, humidity and smells.
  • The process of the heat recovery system results in an energy-efficient outcome, meaning that there is a possibility you can save money on energy bills in the long term.
  • 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.

Benefits of heat recovery systems

Here are some further benefits of having a heat recovery unit:

  • 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.

What are the different types of heat recovery systems?

There are two different types of heat recovery systems, those being single-room, and whole house. So what’s the difference?

Single-room heat recovery systems

As the names suggest, single-room heat recovery systems operate for usage in one room, the rooms they would generally be installed in would be utility rooms, bathrooms and kitchens. Single-room heat recovery systems are ideal for these rooms as they are likely to lose a little more heat due to windows being open (to let steam or smells escape)

Whole house heat recovery systems

Again, as the name alludes to, a whole house heat recovery system operates for usage of your whole house, this means it would generally need to be in a central area above the rooms in your home, such as a loft in your upstairs landing.

Whole house heat recovery systems are ideal for those who live in older homes, or large homes, and it is also appropriate for those with modern homes who have a difficult time regulating the temperature in their homes.

Which heat recovery system should I pick?

Firstly, you should assess if you have issues with humidity or condensation in rooms aside from your utility room, bathrooms and kitchen. If you do, then it would be worth investing in a whole house heat recovery system. Otherwise, a single room system may be ideal for you.

We understand that it isn’t easy for everybody to know which option is the best suited for their situation, that’s why we urge you to get in touch if you have any questions, we are always happy to help!

Do heat recovery systems kill mould?

No, heat recovery systems do not directly destroy mould, if you already have mould in your home, having a heat recovery system will not make it disappear, you must address it by removing it, this can be done through mould removal products / addressing the cause of the mould.

That being said, heat recovery systems serve to prevent the environment necessary for mould to grow. Although it can’t kill mould, it can make sure the environment is not habitable for it.

Can I ventilate without a heat recovery system?

Can I ventilate without a heat recovery system?

Yes, you can ventilate your space without a heat recovery system, you can also use an extractor fan, if any technology is not an option for you, then you would have to manually ventilate by doing a ventilation routine.

A ventilation routine is something that should be pracitced daily, its as simple as opening your windows on both levels (or one if you’re in a flat/bungalow) and sides of the home, creating a passage for the air to travel through.

This should be done for around 20 minutes daily to ensure a level of ventilation in your home, although this method is not exactly perfect for everyone.

Can I remove mould without a heat recovery system?

Yes, as we highlighted earlier, heat recovery systems change the environment that mould thrives on, it does not get rid of mould that is already there. Here are some options for mould removal.

Option 1: Natural Solutions

If you are looking for natural alternatives to get rid of mould, try using distilled white vinegar, the acidic properties in the vinegar helps to dissolve the mould. (This method may prove to be ineffective against a large collection of mould, so don’t rely on this method entirely.)

If there are noticeable and effective results, repeat until it is completely gone. If it fails, this means that the mould is penetrated deeper than surface level, if mould control solutions don’t make an improvement, it is best to call local mould cleaning services.

Option 2: Products

Mould removal products have special substances that prevent mould from coming back (depending on the severity) This is definitely worth a try especially if natural solutions didn’t work
