Residential MVHR

Modern MVHR units can recover up to 90% or more of the heat that would otherwise be lost through ventilation. By reusing this heat, the heating system has less work to do, helping reduce overall energy consumption and heating costs. Actual savings will depend on the building's insulation levels, airtightness, and occupancy patterns.

While MVHR systems are most commonly installed in new-build and highly airtight properties, they can also be incorporated into renovation projects. The suitability of an existing property depends on factors such as available ductwork routes, building layout, and overall airtightness. A professional assessment can determine the best solution.

MVHR systems are designed for long-term, reliable operation. Routine maintenance typically involves inspecting and replacing air filters at recommended intervals and ensuring air terminals remain clean and unobstructed. Regular servicing helps maintain optimum performance and efficiency.

The main difference is that an MEV system extracts air without recovering heat, whereas an MVHR system both extracts stale air and supplies fresh air while recovering heat from the exhaust air. MEV systems are generally simpler and more cost-effective to install, while MVHR systems offer additional energy-saving benefits through heat recovery.

MEV systems are commonly installed in houses, apartments, student accommodation, care facilities, and other buildings where continuous ventilation is required. They provide a practical solution for maintaining air quality and moisture control in both domestic and light commercial applications.
