How Do Heat Recovery Systems Work?

A heat recovery system can certainly save on energy bills and keep you warmer in the winter. New build houses can boast up to 30% savings on heating bills.

Everyone wants their house to be as airtight as possible to get the most out of their heating, however, this can cause poorer air quality (as there are no sources of natural ventilation) this can significantly increase the effects of asthma and other respiratory problems. Other issues can be condensation, mould, dust mites, unpleasant smells and the build-up of toxic gases.

If you install a heat recovery system it will extract the moist, stale air from all the wet rooms in your house and replace it with clean, filtered, fresh, warm air to all your habitable rooms and bedrooms without letting the heat escape. Your home will be fully ventilated throughout the year with as much as 95% of the normally wasted heat being recovered providing you with substantial energy savings. This heat recovery system allows your property to stay air tight with no window vents or bathroom extractors being required, creating a healthier, cleaner and quieter environment.

With a heat recovery system, you make use of what already exists as well as reduce our collective impact on the environment, and that includes the amount of heat we lose to the environment daily. Heat recovery systems work by using the valuable warm air or water in a property and use it in a positive way.

With technology moving forward into greener energy, heat recovery systems are a perfect example of how we are trying to improve our own quality of living as well as being energy efficient. A heat recovery system helps the air circulate within a building by replacing it with colder air that is warmed by the ventilation system.

For a home a heat recovery system could save on energy bills and help keep the house warm during the winter months. It costs money to heat our homes but if we open a window or a door that warm air simply goes out into the atmosphere. With a ventilation system you have a constant supply of warm, fresh air circulating throughout your home. For businesses and industry on the other hand, heat recovery helps make the work place a far more efficient place.

How does it work?

A heat recovery system works via a ventilation system which is usually located within the attic or the roof space of a building. Rather than just draw out and replace the air with the air from outside, a heat recovery system draws the heat from the outgoing air and passes it to the air which is being filtered in from outside. (on all our systems the airstreams do not touch meaning no cross contamination)

A heat recovery system works independently of your normal heating system, in each room there are ventilation ducts with filters that supply air in and out of each room which all leads to a heat exchanger. The heat exchanger is the core of the heat recovery system, by moving the stale air through the pipes whilst drawing in cold air from the outside via other ducts.

These airflows pass one another without mixing physically, but the heat is extracted from the cold stale air which is then fed back down through the pipework and into each room. The stale air has its heat extracted and then is extracted out and into the atmosphere.

Over the years the technology for heat recovery systems has vastly improved and there are now systems available that profess extract up to 95% of the heat from stale air and return it to the fresh air that is circulating back into the system.

Depending on the building that you are looking to ventilate there are different systems to maximise the value of wasted energy, converting it to something useful and that can bring down costs as well as reduce the impact that you have on the environment.

To get the best results of your heat recovery system for your home or building, you need to ensure that the building in question is fully insulated and all the areas where warm air can escape be sealed. This may rule out some older buildings as they tend to lose more heat than newer, more eco-friendly buildings.

Nowadays most heat recovery systems behave smartly, reducing the amount of heat that is extracted during the summer months so that comfort levels are maintained or instead can be used for drawing more heat from areas such as a kitchen or wet room where the temperature is likely to be higher. In offices or working buildings they can be used to keep workers cool during the summer months and warmer in the winter without the need to open windows are use heaters wastefully.

Some of the key benefits of a MVHR are that they provide high quality fresh air throughout the building by extracting the stale air and recycling it into clean fresh air. They reduce dust and pollen throughout the house and are collected via a filter within your system. They greatly reduce moisture and smells cause by cooking as well as greatly reduce energy usage with your home.

The maintenance of a heat recovery system is virtually none as all you would have to do is change the filters within the system once or twice a year. The MVHR system constantly provides a high quality of air throughout your home, as the air is being filtered before being distributed it tends to be dust free.
