Non-heating season operation

The best strategy is to operate your HRV continuously year-round,

even during the non-heating season. Except for adjusting the

dehumidistat setting, operation should be essentially the same

as during the heating season. On the other hand, conventional

permanent split capacitor (PSC) furnace motors are too expensive

to run year-round if they are ducted separately.

You may ﬁnd that operating the HRV keeps the home cooler

and quieter than does opening windows for ventilation. Keeping

windows closed also provides better security and reduces the

amount of pollen and dust entering your home.

By removing some of the heat from incoming air, most HRVs will

reduce the load on the air conditioner and save you money.

All-season operation

Keep contaminants away from the fresh air intake when your

HRV is operating. For example, avoid putting trash next to the

HRV intake, do not use pesticides and herbicides nearby and keep

your barbecue downwind. If you must generate pollutants near the

HRV intake temporarily, turn the HRV off until you complete the

activity.

ENERGY STAR

for HRVs

Effective January 1, 2010, Natural Resources Canada released the

technical speciﬁcation requirements for HRVs and energy recovery

ventilators (ERVs) to become ENERGY STAR qualiﬁed. This

speciﬁcation promotes increased heat recovery and efﬁcient fan

operation. Heat recovery is measured by the sensible heat-recovery

efﬁciency (SRE); the higher the SRE, the higher the rate of heat

transfer. Minimum levels of fan efﬁcacy are based on the SRE value.

To qualify for the ENERGY STAR symbol, HRVs must be tested

by a third party and certiﬁed to meet the requirements of Tables 4A

and 4B.
