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.

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%.

Brands we work with



  • Why should I upgrade my current boiler?
    1. Reliability. Because boilers have moving parts, electronics and metal that can corrode, boilers have a natural lifespan and eventually need to be replaced in order to keep up efficiency and reliability. 2. Controlling costs. Heating your home is one of the largest cost of living in a house. Condensing boilers consume less fuel (gas/oil) but still give the same heat output you want. By upgrading to a good, new condensing boiler, your gas bills will be 20% to 30% reduced. 3. The environmental impact.
  • Where is a condensing boiler suitable?
    99% of houses are suitable for condensing boilers without much disruption. Because the boilers produce condensation, this needs to be sent to a drain somewhere, which is the main logistical difference between them and traditional boilers.
  • What size gas boiler do I need for my home?
    Most modern homes in Ireland use system gas boilers with a hot water press. The power output of system gas boilers varies, and the suitable size depends on factors such as the property size. How many bedrooms you have is usually a good indicator of what size boiler you need.
  • How long does it take to replace my gas boiler?
    We can usually replace your gas boiler in one day, however each setup and installation is slightly different so in some cases we may need 2 days - but this is rare.
