What Is an Exhaust Air Heat Pump (EAHP) and Why Is It Essential for Modern Quebec Homes?
An Exhaust Air Heat Pump (EAHP) is a compact, high-efficiency system that extracts heat from stale exhaust air leaving your home — typically from bathrooms, kitchens, and laundry rooms — and uses it to pre-heat incoming fresh air or directly heat living spaces. Unlike traditional HRVs (Heat Recovery Ventilators), which only transfer heat between air streams, an EAHP actively uses a heat pump cycle to amplify recovered heat, making it powerful enough to contribute significantly to space heating — even in cold climates like Quebec’s.
In today’s energy-efficient homes — especially those built to Passive House or Net-Zero standards — airtight construction prevents natural air leakage, which can lead to poor indoor air quality if unmanaged. An EAHP solves this problem elegantly: it ensures constant, filtered ventilation while recovering nearly all the heat that would otherwise be lost. This reduces overall heating demand by up to 50%, slashes electricity use compared to electric baseboards, and eliminates musty odors, excess humidity, and mold risk. For homeowners seeking sustainability, health, and quiet comfort without sacrificing aesthetics, the EAHP is not just an upgrade — it’s a necessity.
Choosing an Exhaust Air Heat Pump means choosing intelligent, integrated climate control designed for the future of residential building. Let Thermopompe Montréal help you install a seamless, high-performance EAHP system tailored to your home’s ventilation needs.
