Heat Recovery Ventilation

In today’s well-insulated and airtight buildings, proper ventilation is crucial for maintaining a healthy indoor environment. HRV systems offer a controlled mechanical solution to this challenge.

How do they work?

HRV systems operate between two air sources at different temperatures. The outgoing stale air from inside the building, typically around 21°C, passes over a heat exchanger. This heat exchanger warms up to approximately 20°C. Meanwhile, fresh outdoor air at around 5°C is sent over the other side of the heat exchanger, without mixing with the stale air. As a result, the incoming fresh air rises to a comfortable 19°C.

Benefits

Controlled Ventilation

Airflows are fixed for all rooms, ensuring the correct level of ventilation.

Humidity Control

HRV helps prevent spore growth caused by high humidity, benefiting those with respiratory issues.

Mold Prevention

By maintaining optimal humidity levels, HRV reduces the risk of mold growth.

Odor Removal

Stale smells can be efficiently ventilated.

Bathroom & Kitchen Clearance

Some HRV units include built-in humidity sensors to automatically adjust ventilation during activities like showering or cooking.

Amount: €1,500

SEAI are offering grants of €1,500 to everyone upgrading their heating controls along with the gas boiler. To receive this grant, you need to also upgrade your central heating controls and we can easily perform all this for you in a day or two.

Why are SEAI offering Grants?

If your gas boiler is more than 4 years old, chances are, it's about 65% fuel efficient, no matter what brand name or how aged it may look. Before July 2008, the Building Regulations did not specify how efficient the boiler had to be. Therefore, Ireland has way too many inefficient boilers.

Changes in the building regulations in July 2008 have specified minimum seasonal net efficiencies of 86% for all domestic boilers. Our gas boilers far surpass this with seasonal net efficiencies of up to 91.2%.
