Are Heat Recovery and Ventilation Systems Worth It?

The demand for well insulated houses has significantly grown in the last decade. This in turn has caused poorer air quality which can significantly increase the effects of asthma and other respiratory problems, health problems, condensation, mould, dust mites, unpleasant smells and build-up of toxic gases. If you want to reduce your heating costs, have a constant supply of fresh, filtered air in your home, no mould, mildew or condensation then a heat recovery system is for you.

If you are building a new house, there is no doubt that a heat recovery system can offer substantial savings on your heating bills. A heat recovery system could recover up to 90% of the normally wasted heat and reduce your heating requirements by up to 25%. Your initial investment could be paid back within five years. Of course, factors like the air tightness of your property must come into the equation but an office with a heat exchanger of above 80% efficiency would save approximately 30% of a heating loads, also mention that the cost to run these systems is around 10 p per day.

Under the right circumstances there’s no doubt that a heat recovery system can produce great benefits for reducing the amount of heat and energy you use which means recycling a significant percentage so that little goes to waste. Whether the current building is suitable for a heat recovery system will depend on the structure of the building. If it is a new build that is air tight a heat recovery system can show significant savings.

A ventilation system normally would be installed in somewhere out of the way like the attic and pipes then fed down to each individual room drawing out stale air and replacing it with fresh air. The way a heat recovery does this is by taking the heat that is currently indoors and passes it onto the new air coming in from outside.As new-builds are starting to come with this sort of technology it means that they would benefit greatly and particularly where are offices are concerned they would benefit greatly form a heat recovery system. For an older property retro-fitting is entirely possible but it comes with a big caveat, older houses are less airtight then newer buildings and to get the benefits from a heat recovery system you really need to have all source of heat loss covered.

How a mechanical heat recovery system (MVHR) works is by taking the heat from the air leaving the building by using a heat-exchanger in the roof. What this does is pass the incoming fresh air which is then pumped around the building. If you are looking to achieve Passivhaus levels of air tightness, then a MVHR is a must. Within older buildings that have a persistent issue with dampness and mould, MVHR units are a blessing that will help eliminate these ongoing issues.


To get the most out of your heat recovery system we recommend that the building is reasonably airtight and weatherproofed, but we have successfully installed systems from period houses to castles treating indoor air quality, damp, mould and condensation issues which cannot be treated with the usual damp prevention methods. These properties will not achieve over 80% heat recovery due to air leakage, but the quality of living was drastically improved and were well worth the investment in a heat recovery systems.

Before You Consider a Heat Recovery System

things to consider

There are many aspects to take into consideration before you invest in a heat recovery system. Before you consider investing into a system you should take into consideration a few of these points:

  • Do you have cavity wall insulation?
  • How much heat is being lost through the floor?
  • Do you have the right grade of double glazing?
  • How is your roof insulated?

It is always a good idea assess what your current situation is before you start installing a new heat recovery system, if you require any help we here at BPC are always happy to help with any enquiry that you may have so get in touch with any queries you may have.

Benefits of Home Ventilation Systems

A home that has been well designed and installed a home ventilation system will offer good ventilation by continuously replacing air throughout the building. If dampness is a main concern, address the source of the moisture problem before considering ventilation systems. You will often be able to address the source of moisture yourself without having to invest in a ventilation system.

Some of the key aspects of making sure that you get the most out of your ventilation system rely heavily on certain conditions that need to be met. If you are trying to ventilate your home, then certain factors need to be considered. If you are trying to ventilate your home by opening windows you may be ventilating your home to a certain extent, but you are then allowing cold unfiltered air to pass through. If you decide to you use extractor fans to vent to the outside of the building, they will solely act as a direct draft as they only extracting air and if it’s not powered on its basically a hole for air to get into your building.

Dampness promotes mould and dust mites into your home which can cause respiratory problems, whilst ventilation systems reduce the symptoms of the problem they also help filtrate the air in and out of your home. Some of the symptoms of dampness are easily detectable, some them being:


  • Musty smells
  • Damp or mouldy clothing
  • Mould forming behind furniture, pictures etc.
  • Mould stains or water marks
  • Rotting Wood

Note that condensation on windows (especially in bathrooms) doesn’t necessarily show signs of excessive dampness as this mainly occurs during winter. A home ventilation system helps eradicate these issues as it works by taking the damp moist air out of the room and filters it to outside and circulates clean fresh air back into the building.

One of the key features of ventilation and heat recovery systems is that you can control the ventilation throughout your building. Within the UK and Ireland, a major concern is far too much uncontrolled ventilation and very little controlled ventilation.

Uncontrolled ventilation is where you would have natural ventilation in your building which you can’t turn on or off, for example draughts around windows, pipes and outside services would contribute to uncontrolled ventilation. Some systems are different than others, so they are greater controllers of controlled ventilation by making a controlled number of air changes per hour or per minute.
