Home Heat Recovery Ventilation Systems & all the information you need to know!

When we started designing and supplying heat recovery ventilation systems the main reason to have a heat recovery system was to recover the heat normally lost through the conventional bathroom extractor fans and air supply vents built into the windows and walls in every room and a heat recovery system achieves this very well with recovering over 90% of the normally lost heat.

But a heat recovery system does so much more and is now more important than most other systems you will be installing into your home!

  • Improving the indoor air quality by filtering all the incoming air
  • Prevents mould and condensation
  • Provides natural cooling in warm weather by supplying fresh filtered air
  • Removes bad odours
  • Helps with asthma and other health issues
  • Distributes heat evenly throughout your home
  • Eliminates the need for bathroom extractor fans and window air vents
  • Complies with all building control regulations
  • And of course, recovers up to 90% of your normally wasted heat

Building control and legislation?

Over the last decade there has been increasing demand on builders, architects and government legislation to increase the thermal efficiency of our homes making them draught free and well insulated. 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.

For health reasons Government legislation now makes it almost compulsory for your new air tight home to have a balanced mechanical ventilation system and a heat recovery ventilation system is the most preferred option.


A ventilation system with heat recovery (HRV) or (MVHR) is an energy efficient, controlled and balanced ventilation system. It extracts the moist, stale air from all the wet rooms in your house and replaces it with filtered, fresh, recovered warm air to all your habitable rooms and bedrooms without letting the heat escape.

Your home is fully ventilated throughout the year with as much as 95% of the normally wasted heat being recovered providing you substantial energy savings. This heat recovery ventilation allows your property to stay air tight with no window vents or bathroom extractors being required, creating a healthier and quieter environment.

Can you install heat recovery ventilation to an existing house?

It is possible to install to an existing house, but good planning and design is critical, If your house is a bungalow the installation would be very easy as all ductwork would be in your attic space but if your house has a number of floors we would have to work with you to provide solutions to drop ductwork to the rooms below through service voids like wardrobes and storage rooms

Can you install in a period house with normal levels of insulation?

We have installed systems to a lot of period houses and even a castle, you will not be able to achieve the maximum heat recovery rate of 90% but you will achieve almost all the advantages including fresh filtered air and condensation control
