Why do we need HRV?

Now days buildings are now a lot more insulated and air tight, so it is vital that a suitable ventilation system is in place. With the current building regulations, installing a heat recovery unit is becoming a necessity rather than a choice. It is important that you have adequate air supply to all rooms and extraction from bathrooms and kitchens. Insufficient ventilation can lead to mould growth, condensation damage and unhealthy living conditions. Our team at Energywise can advise you on the most suitable ventilation system to match your home's airtightness level. Why not email us your drawings, our experts will design your system for you and provide you advice and a free no obligation quotation?

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. Since the energy of the extracted air is transferred to the fresh. This means maximising energy for minimum cost. The filtered and, consequently, cleaner air increases the comfort for you and your family.

How does heat recovery ventilation work?

1. Heat recovery ventilation systems are designed to recover up to 95% of the heat normally lost through open windows, vents and other breakout points.
2. Fresh air is continuously drawn into the home via a low energy heat recovery ventilation unit, usually located in the attic or utility area.
3. Once passed through the heat exchanger within the HRV ventilation system, the warm, clean, fresh, filtered air is distributed around the home through a series of ducts. Since the energy of the extracted air is transferred to the fresh, cool outdoor air, 95% of the heat is retained. That means no waste of energy.
4. Air from wet rooms e.g. bathrooms, kitchens, etc. is continuously extracted and filtered back through the heat recovery ventilation unit. The heat from the extracted air is transferred to the fresh incoming air. HRV can also dissipate warm air from your home in Summer, bringing in cool, fresh air from outside.
5. With an auto summer by-pass, the HRV unit automatically controls whether to reclaim heat energy (or not) based on temperature. This ensures that your house does not get over-heated while still remaining air-fresh.
