What Is Heat Recovery Ventilation?
Heat Recovery Ventilation (HRV), also known as Mechanical Ventilation with Heat Recovery (MVHR), is a whole-house ventilation system that continuously supplies your home with fresh, filtered air — while recovering up to 95% of the heat from the outgoing stale air.
In Ireland's damp climate, homes are tightly sealed for energy efficiency, which traps moisture, allergens, and pollutants indoors. An MVHR system solves this by maintaining a constant, controlled exchange of air without losing the warmth you've paid to generate.
Unlike simply opening a window — which wastes heat and lets in unfiltered outdoor air — an MVHR system filters pollen, dust, and pollutants while maintaining comfortable indoor temperatures year-round.

How MVHR Systems Work
A simple, elegant process that runs silently in the background — keeping your home fresh, warm, and healthy 24 hours a day.
Stale Air Extracted
Warm, moist, stale air is continuously drawn from wet rooms — bathrooms, kitchen, and utility room — through a network of ducts.
Heat Exchanger Core
The outgoing warm air passes through a highly efficient heat exchanger core, transferring up to 95% of its heat energy to the incoming fresh air stream — without the two airstreams mixing.
Fresh Air Filtered
Incoming fresh air from outside is drawn through F7-grade filters, removing pollen, dust, mould spores, and fine particulates before it enters your home.
Warm Fresh Air Supplied
The now-warmed, filtered fresh air is distributed to living rooms, bedrooms, and hallways — maintaining comfortable temperatures without draughts.
The Science Behind the Savings
Benefits of MVHR for Irish Homes
Heat recovery ventilation delivers measurable improvements to your home's energy performance, air quality, and long-term value.
Significant Energy Savings
By recovering up to 95% of heat from outgoing air, MVHR systems dramatically reduce the energy needed to heat your home. Most Irish homeowners see a noticeable reduction in heating bills within the first winter.
Superior Indoor Air Quality
Continuous fresh, filtered air means lower CO₂ levels, reduced VOCs, and fewer airborne allergens. Families with asthma, hay fever, or respiratory conditions report significant improvements in symptoms.
Eliminates Condensation & Mould
By continuously removing moisture-laden air from bathrooms and kitchens, MVHR systems prevent the condensation that leads to mould growth — protecting your home and your health permanently.
Comfortable Year-Round Temperature
In summer, the heat exchanger works in reverse — pre-cooling incoming air using the cooler indoor air. Your home stays comfortable without expensive air conditioning.
Reduced Carbon Footprint
Lower energy consumption means lower CO₂ emissions. MVHR systems are a key component of nearly zero-energy buildings (nZEB) and support Ireland's climate action targets.
Increased Property Value
Homes with MVHR systems achieve higher BER ratings, which directly increases property value and attractiveness to buyers. A better BER can add thousands to your home's market value.

Energy Savings & Indoor Air Quality
MVHR systems deliver two powerful benefits simultaneously — dramatically lower energy bills and measurably healthier indoor air.
Heating Cost Reduction
Irish homes lose a significant portion of their heat through ventilation. MVHR recovers up to 95% of that heat, meaning your boiler works far less to maintain comfortable temperatures. Most homeowners save €300–€800 per year on heating bills.
Healthier Indoor Air
Indoor air can be 2–5x more polluted than outdoor air. MVHR continuously replaces stale, CO₂-rich air with fresh, filtered air — reducing headaches, fatigue, and respiratory issues that many Irish families attribute to other causes.
SEAI Grant Support
The Sustainable Energy Authority of Ireland (SEAI) offers grants for MVHR installation as part of whole-home energy upgrades. Our team will guide you through the grant application process to maximise your savings.
nZEB Compliance
New Irish building regulations require nearly zero-energy building (nZEB) standards. MVHR is a core component of achieving nZEB compliance — making it essential for new builds and major renovations.

From survey to a fully commissioned system — here is exactly what to expect. Professional, clean, and completed on time.
Free Home Survey
A certified MVHR specialist visits your home to assess room layout, existing ductwork opportunities, insulation levels, and ventilation requirements. We take measurements and discuss your goals.
System Design & Quote
We design a bespoke MVHR system for your home — calculating airflow rates for every room, planning duct routes, and selecting the right unit. You receive a detailed fixed-price quote within 24 hours.
Unit & Ductwork Installation
Our installation team fits the MVHR unit — typically in a utility room, attic, or hot press — and runs insulated ductwork to all supply and extract points throughout the home. We work cleanly and efficiently.
Grille & Terminal Fitting
Supply and extract grilles are fitted in each room. We use low-profile, paintable grilles that blend seamlessly with your décor. External terminals are fitted with bird guards and weather-resistant covers.
Commissioning & Balancing
Every MVHR system we install is professionally commissioned using calibrated airflow measurement equipment. We balance each room to the correct airflow rates as specified in Irish Building Regulations Part F.
Handover & Training
We walk you through the controls, filter change schedule, and seasonal settings. You receive full documentation including commissioning report, warranty certificates, and our direct aftercare contact.

MVHR Maintenance Tips
A well-maintained MVHR system will perform at peak efficiency for 20+ years. Here is what is needed to keep your system running perfectly.
Filter Replacement
Every 6–12 monthsMVHR filters (typically G4 and F7 grade) should be replaced every 6–12 months depending on local air quality and usage. Blocked filters reduce efficiency and can damage the unit.
Annual System Inspection
Once per yearA full annual service includes checking airflow rates, inspecting ductwork for leaks, cleaning heat exchanger core, and verifying all controls are functioning correctly.
Duct Cleaning
Every 3–5 yearsOver time, dust and debris can accumulate in ductwork. Professional duct cleaning ensures maximum airflow efficiency and prevents contamination of your indoor air supply.
Summer Bypass Check
SeasonallyMost MVHR units have a summer bypass mode that allows cool night air in without heat recovery. Checking this function each spring ensures optimal summer comfort.
External Terminal Inspection
AnnuallyExternal intake and exhaust terminals should be checked for blockages from leaves, bird nests, or debris — particularly after autumn and winter.
