Are Heat Recovery Systems Noisy?

Heat recovery systems not only protect your home from an environment that mould can thrive in, it also plays a part in maintaining the heat that would otherwise be lost in an extractor. But are heat recovery systems noisy?

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 101

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.

How do I know if I need a heat recovery system?

You know you need a heat recovery system if:

  • Rooms that have extractor fans are a lot colder than rooms without one
  • You have to use the central heating often.
  • Certain parts of the house has frequent condensation, or mould.
  • You’re looking for additional long term investments that can help to save on your energy bills.
  • You have allergies to airborne components

If any of these factors applies to you, we strongly suggest you explore the option of having a heat recovery system, we also encourage you to get in contact with us to answer any questions you may have.

Are heat recovery systems noisy?

Are heat recovery systems noisy?

Single-room heat recovery systems such as our Kair Heat Recovery Extractor Fan – 12VAC SELV – Humidistat have a decibel rating of 21- 45 decibels, which realistically is not enough to cause a disturbance.

When it comes to whole-house heat recovery systems, even though they are larger units they surprisingly are only nominally higher than their single-room counterparts. Take our Vent Axia Sentinel Kinetic B Boxed Whole House Heat Recovery Unit (438222), which has sound levels ranging from 22-49 decibels.

With whole house units, especially ones that continuously work, the benefit is that it will be in a loft space where nobody frequents, so any noise will be nominal. When it comes to single room units, they generally are only on for a short period of time (depending on your settings) so again, this level of noise isn’t enough to disturb the neighbours, let alone yourself.

Can heat recovery systems get louder over time?

In theory, yes. Heat recovery systems can get louder over time, but if this did happen, it would likely only be due to one key factor, maintenance.

If you clean and inspect the ducting regularly, you should be okay, if dust accumulates, you could experience a louder usage due to air travelling through the smaller spaces. Be sure to check your ducts annually for any issues, any cuts or breakage in the ducting will also affects its noise output, as well as its efficiency.

Do heat recovery systems take up space?

Do heat recovery systems take up space?

Heat recovery systems vary in size due to the variety of models, but single room units generally do not take up space more than any other extractor. Of course, whole house units will take up space, in terms of setting up ventilation, as well as the unit itself.

But, whole house units are generally located in your loft, which if you don’t use as a room, shouldn’t take up any noticeable space in your home.

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 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
