Mechanical Ventilation with Heat Recovery (MVHR)

Whole-Home Fresh Air with Energy Efficiency Built In

Modern homes are built to be airtight for energy efficiency. However, without proper ventilation, this can lead to stale air, excess humidity, and poor indoor air quality. Xpelair’s Mechanical Ventilation with Heat Recovery (MVHR) systems help solve this issue by delivering a constant supply of fresh, filtered air while recovering heat from outgoing air.

“The Future of Indoor Air Quality in UK Homes and its Impact on Health”

- a report by Professor Hazim Awbi, at The University of Reading, stating the health risks associated with poorly ventilated homes in no uncertain terms. The research cites MVHR as the most cost-effective solution for achieving an energy-efficient air exchange rate and a healthy environment for building occupants.

Considerations for Installers and Specifiers

Designed for Whole-Dwelling Ventilation

MVHR systems like Xpelair Natural Air provide continuous ventilation by supplying fresh, filtered air to rooms and extracting stale air from kitchens and bathrooms. This eliminates the need for background ventilators in windows.

Installer-Friendly Features

Quick-access panels, intuitive wiring layouts, and integrated dataloggers make installation and commissioning straightforward. The units also include filter change alerts and front-facing service access to reduce maintenance time.

Support at Every Stage

From design consultation to post-installation support, Xpelair offers technical guidance, training resources, and documentation to help specifiers and installers deliver their ventilation solutions.
