Ventilation

Heat recovery ventilation systems work by supplying and extracting air throughout your home, 24 hours a day, 7 days a week to give continuously good air quality.

Air is extracted continuously from the wet rooms in the house (I.e. the kitchen and bathrooms). This air passes into the ventilation device and over the heat exchanger unit, which can recover up to 90% of the heat in the air that would otherwise be lost.

At the same time, air is continuously drawn in from the atmosphere and ducted to habitable rooms (living rooms and bedrooms) to provide a balanced ventilation system.

How does it work?

A heat recovery system will take air from the bathroom, kitchen, toilet and utility (wet/smelly) rooms and pass it through a duct into the Heat Recovery unit before passing it to outside. Clean air is then drawn in from outside to the heat recovery unit before distributing it through another duct system to living spaces.

Heat exchange takes place within the appliance by blowing the outgoing stale but warm air through adjoining channels to the incoming fresh cooler air which is blown in the opposite direction.


The benefits:

lower fuel bills

lower carbon emissions

salvages and re-introduces heat into the property which would
otherwise have been lost

the energy saving contributes to a reduced DER (Dwelling EmissionRate) in SAP

Heat recovery uses just a few Watts of energy (<1W/l/s) to recovery many kiloWatts of otherwise lost heat


The costs:

the supply, installation and commissioning cost for a heat recovery system in a property, normally costs between £4,000 to £6,000.

single units can be installed in bathrooms, to recover heat at a cost of around £400.


Heat recovery ventilation, also known as HRV, Mechanical ventilation heat recovery, or MVHR, is an energy recovery ventilation system, using equipment known as a heat recovery ventilator, Heat exchanger, air exchanger or air-to-air exchanger, that employs a counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow.
