Introduction

The importance of ventilation in today’s more energy-efﬁcient

homes is universally recognized. Introduced as a requirement for

airtight R-2000* homes, continuous ventilation systems are now

common in new housing and major home renovations. Because of

the energy savings generated, the system of choice is often a heat

recovery ventilator (HRV) or energy recovery ventilator (ERV).

During the remainder of this publication, we will refer only to HRV;

however, please note that this applies to both HRVs and ERVs.

An HRV is a mechanical ventilation device that helps make your

home healthier, cleaner and more comfortable. It does so by

continuously replacing stale indoor air with fresh outdoor air. HRVs

are set apart from other mechanical ventilation devices. Their ability

to exchange heat between the supply and exhaust air streams reduces

the cost of heating or cooling the healthy fresh air circulating through

the home. HRVs are sometimes called air-to-air heat exchangers

because they preheat or cool incoming air using exhaust air.

This booklet discusses the need for mechanical ventilation in

homes. It also explains the components of an HRV system, how

to operate and maintain the system, and how to solve operating

problems. You will ﬁnd this information useful, whether you

occupy a home with an HRV or plan to have one installed.

There are many types of HRVs on the market, as well as different

installation strategies. The size of your house, type of heating

system and geographical location, for example, can affect the

kind of system you have and the way it has been installed. The

diagrams in this booklet give examples of the types of systems

available; they are provided for information only.

This booklet is intended to supplement your HRV owner’s

manual, not replace it. If you need a manual or more information

on operating procedures for your HRV, contact the installer or

manufacturer.
