Heat Recovery Ventilation
Introduction
As the building regulations for new homes become more demanding, resulting in higher levels of insulation and increased airtightness, easy access to fresh air within the building is something that needs to be considered. Indeed, the concept of a “Passive House” (i.e. a house that loses no heat, or where heat loss is absolutely minimal) is based on the principle that the building is effectively sealed and no air enters or leaves the building in an uncontrolled manner.
As you might expect, the air indoors can quickly become contaminated with pollutants such as dust, pollen and even carbon monoxide. According to experts in this area, the air inside your home should be exchanged with fresh air at least 8 times in a 24-hour period. The reality is somewhat different, with the average home having 5 (or less) air exchanges every day.
Heat Recovery and Ventilation systems present an effective remedy to this potentially unhealthy situation, by removing dust and pollen from the air (which alleviates sufferers from asthma), extracting and expelling carbon monoxide and reducing the burden of utility bills.

How does HRV work?
While most people will be familiar with mechanical ventilation systems such as a bathroom ventilation fan or an extractor fan over the cooker, it’s important to note that these are only used to extract air. A Heat Recovery & Ventilation system not only extracts air, but it also replaces it with fresh outdoor air, and it uses a heat exchanger inside the ventilator to absorb the heat from the stale, outgoing air, to pre-heat the incoming fresh air.
A properly installed Heat Recovery and Ventilation system will ensure that the moist, contaminated exhaust air is continuously replaced with temperature controlled, filtered fresh air, thus creating controlled and balanced ventilation within the building.
