Ventilation & MVHR FAQs
An MVHR system costs €4,000 to €7,000 in a new build (where ducting is installed during construction) and €7,000 to €12,000 in a retrofit (where ducting must be routed through an existing house). The cost depends on the brand, unit capacity, and the complexity of the duct layout. Demand-controlled ventilation (DCV) costs €1,500 to €3,000. Positive input ventilation (PIV) costs €500 to €1,500.
In a well-insulated, airtight home (air permeability below 5 m³/hr/m²), MVHR is essential for maintaining healthy indoor air quality while recovering up to 90% of heat that would otherwise be lost. It prevents condensation, mould, and stuffy air. In a leaky, poorly insulated home, MVHR is not cost-effective because air enters through gaps rather than through the heat exchanger. For these homes, demand-controlled ventilation or PIV is a better starting point.
Filters should be replaced every 6 to 12 months (more frequently if you live near a busy road or in a dusty area). The heat exchanger should be cleaned annually. Ducts should be inspected and cleaned every 3 to 5 years. Annual professional servicing costs €100 to €200. Most filter replacements are straightforward enough to do yourself, keeping ongoing costs low.
A properly installed and commissioned MVHR system operates at 25 to 30 decibels on normal speed, which is quieter than a whisper and virtually inaudible in a furnished room. Noise problems are almost always caused by poor installation: undersized ducts, uninsulated duct runs, the unit mounted directly on joists without vibration isolators, or incorrect fan speed settings. Insist on proper commissioning.
A bathroom extractor fan removes moist air from one room and expels it outside, losing all the heat it contains. MVHR is a whole-house system that continuously ventilates every room while recovering 85-90% of the heat from the extracted air. MVHR also supplies filtered fresh air, removing pollen, dust, and pollution. It is a fundamentally different level of ventilation and air quality.
Yes. Condensation and mould in insulated homes are caused by trapped moisture that has no way to escape. MVHR continuously removes moist air from kitchens and bathrooms and replaces it with dry, filtered fresh air. In homes where condensation and mould have been a persistent problem after insulation, MVHR almost always resolves the issue completely.
