What is a Heat Recovery Ventilator (HRV) ?

A Heat Recovery Ventilator (HRV) is essentially a “lungs and heat-swapper” for your home. In modern, airtight houses, stale air gets trapped. An HRV solves this by swapping that stale air for fresh air while “stealing” the heat from the outgoing air to warm up the incoming air.

How Does Heat Recovery Ventilator (HRV) Work?

1. Central Component

The HRV Unit: A central box that connects to four distinct air paths.

2. Extraction (Stale Air Out)

Source: Pulls stale, warm, humid air from “wet” rooms (e.g., kitchen, bathrooms).
Direction: Air moves from these rooms toward the HRV unit.

3. The Heat Exchange (The Core)

Location: Inside the HRV unit.
Component: A heat exchange core (thin plates made of plastic or aluminum).
Process: Warm outgoing air and cold incoming air pass through the core in alternating channels.
Critical Feature: The two air streams never mix — they only pass close to each other.
Result: Heat from the warm air radiates through the thin plates, pre-warming the cold incoming air.

4. Fresh Air Supply (To Living Spaces)

Path: Pre-warmed fresh air is filtered and blown into “living” rooms (e.g., bedrooms, living room).

5. Exhaust (Out of the House)

Path: The now-chilled, stale air is exhausted outside the house.
