Heat Recovery Ventilation Cost: Real Prices, SEAI Grants & Savings in Ireland
Understanding the heat recovery ventilation cost is essential for Irish homeowners planning energy-efficient upgrades. Although the cost of a heat recovery ventilation system varies by house size and layout, MVHR remains one of the most effective ways to reduce heating demand while improving indoor air quality. Moreover, SEAI guidance highlights where these systems are appropriate and how they contribute to overall energy performance.
Energy Efficiency Data (SEAI)
According to the Sustainable Energy Authority of Ireland (SEAI), heat recovery ventilation can reduce space-heating demand by 20–30% in modern A-rated homes. This reduction occurs because MVHR systems recover heat from outgoing stale air and use it to pre-warm incoming fresh air.
For full technical details, homeowners can review the official SEAI ventilation guidance.
SEAI Grants & Ventilation Grant Options
When considering the overall cost of a heat recovery ventilation system, it’s natural to ask whether SEAI grants apply. Homeowners may access support for mechanical ventilation upgrades through the SEAI Home Energy Upgrade Scheme delivered by accredited One-Stop Shops.
However, it’s important to note:
Eco Vent is not currently registered as an SEAI contractor, so MVHR installations completed by us do not qualify for the SEAI ventilation grant.
Despite this, our pricing is highly competitive, often reducing or even eliminating the difference compared to grant-eligible services.
BER Ratings & Home Performance
The Central Statistics Office (CSO) regularly reports on Building Energy Ratings in Ireland. A-rated homes continue to dominate new-build construction, and heat recovery ventilation plays a major role in maintaining consistent airflow while supporting compliance with TGD Part F and NZEB standards.
Cost–Benefit Summary
The heat recovery ventilation cost depends on several factors, including:
- Floor area
- Ducting routes and concealment requirements
- Air-tightness levels
- System type and filtration grade
Even so, MVHR systems typically offer a solid return on investment. Lower heating bills, cleaner filtered air, and balanced ventilation performance help shorten the payback period. When SEAI grant support is available through One-Stop Shops, the value increases further.
