LIFEBREATH METRO 120ERV Air Exchanger Greater Montreal
Is it the right size for your home?
It delivers 125 cfm net, enough to ventilate 1,400 to 2,300 sq ft. Choose your home's living area.
It's the right size.
For a 1,500 to 2,500 sq ft home, about 105 cfm of air needs to be renewed continuously. This unit delivers 125 cfm net — enough for the house, with extra capacity to boost ventilation for the bathroom and kitchen.
Calculation: 0.35 air changes per hour over the living volume, with 9 ft ceilings. Our estimator sets the exact airflow room by room, following CSA F326.
What it does, in numbers
$58.56
Electricity per year
Less than a 100 W light bulb
Bulbs left on day and night. Same calculation for every line: wattage × 8,760 h × 11.142 ¢/kWh.
Airflow and efficiency at 0 °C: HVI directory, Section III. Cost: 60 W over 8,760 h at Hydro-Québec's Rate D second tier (11.142 ¢/kWh).
What you should know about this one
Published, verifiable facts, not brochure claims.
MirrorAvailable mirrored (METRO-120ERV-M)
A mirrored version, with the fresh-air and stale-air paths swapped compared with the standard unit, is sold as METRO-120ERV-M, and a hardwired configuration is also offered. Handy when the ducts arrive from the opposite side.
20.75 inThe narrowest METRO 120 in our catalogue
At 20.75 in wide and 9.75 in high, it is narrower than the METRO 120D and METRO 120 ERVD (25.75 in), an advantage in a tight bulkhead or dropped ceiling. Mounting brackets are included.
ExhaustIt defrosts by pausing the fresh air for a few minutes
In cold weather, the supply fan stops for a few minutes while the exhaust keeps running, so warm indoor air thaws the core. During the cycle the house is briefly under negative pressure; if you have a fireplace or a naturally vented combustion appliance, mention it to our estimator.
ERVIt moves moisture too, not just heat
An ERV transfers some moisture between the two airstreams. Useful in a house that gets too dry in winter or takes on a lot of humidity in summer. The trade-off: it generally recovers less heat than a comparable HRV.
2004838Its HVI certification number
Listed in Section III of the Home Ventilating Institute's certified products directory. Anyone can check it, and it's the first condition for the Rénoclimat grant.
−8 cfmWhat the ducts cost it
Between a nearly unrestricted test bench (0.2 in) and a real duct system (0.4 in), it drops from 133 to 125 cfm. Most spec sheets show only the first number, precisely because it looks better.
60 WMeasured at the airflow it actually runs at
Its 69% at 0 °C is certified at 49 cfm, the continuous airflow of a typical home. At that setting it draws 60 W, or about 526 kWh a year.
5 yearsThe core warranty
The core does the work and is the most expensive part to replace. Motors and parts: 5 years. We register the warranty in your name at commissioning.
5 inWhat it needs on site
5 in ducts, side connection. It weighs 34 lb, and it needs enough clearance to slide the core out once a year.
Rénoclimat: $500 to install or replace an HRV or ERV
First condition met: HVI Section III certified, No. 2004838. Second: your EnerGuide rating must improve between the two evaluations. Québec warns that an air exchanger installed on its own can increase a home's energy use; that's why we balance it to the calculated airflow rather than running it at full speed.
What it needs on site
In a condo with no floor drain, or with little ceiling clearance, we usually look at a side-port model instead. Our estimator checks the location, the drain and the duct route before ordering.
