What is HRV?
What is HRV? HRV or a heat recovery ventilation system remove odour and humid air from kitchens and bathrooms. The same volume of clean, preheated air is supplied to bedrooms and living rooms. As much as 95% of the normally wasted heat is being recovered. Galway Property Services provides expert installation of ventilation system to improve your indoor air quality and energy efficiency..
How does it work?
A heat recovery system works (also called HRV or MVHR) via a heat recovery ventilation unit which is usually located in the attic, roof space or plant room of a building. Rather than just extracting air and replacing it with the air from outside, a heat recovery system draws the heat from the extracted air and passes it to the air which is being filtered in from outside. The extract and supply air do not flow within the same pipes and there would be no cross contamination of the different air flows.
How is a heat recovery system beneficial?
A heat recovery system is beneficial as everyone wants their house to be as airtight as possible to get the most out of their heating, however, this can cause poor air quality due there being no sources of natural ventilation. Having an airtight building with and no ventilation leading to poor indoor air quality can significantly increase the effects of asthma and other respiratory problems. Other issues that can be caused as a result of poor indoor air quality are condensation, mould, dust mites, unpleasant smells and the build-up of toxic gases.
