LIFEBREATH METRO 120 ERVD Greater Montreal Air Exchanger
Is it the right size for your home?
It delivers 123 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 123 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
$61.49
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.
Meets the Québec Construction Code for Greater Montréal. The Code requires 54% at −25 °C below 6,000 degree-days (Montréal, Laval, Longueuil and both shores) and 60% above that. This unit is rated at 57% at 57 cfm.
Airflow and efficiency at 0 °C and −25 °C: HVI directory, Section III. Cost: 63 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.
−25 °CERV certified for cold weather to −25 °C
Unlike the METRO 120 ERV, which has no −25 °C rating, this “D” version carries the HVI cold-weather certification at −25 °C and still needs no drain.
MirrorMirrored METRO-120ERVD-M version available
If the duct layout calls for it, Lifebreath offers a version with the airflow paths reversed (METRO-120ERVD-M) and a hardwired configuration, so the orientation can suit the installation.
57%What it still recovers at −25 °C
The only efficiency figure that matters for a Québec winter, and the one the Code uses. An efficiency quoted without its temperature means nothing; this one is measured at a test airflow of 57 cfm.
DamperIt defrosts without depressurizing the house
In cold weather, a motorized damper closes the outdoor air intake and recirculates indoor air through the core to thaw it. The house doesn't go into negative pressure during the cycle: no cold air drawn in through leaks, and none of the imbalance manufacturers warn about when there's a fireplace or a combustion appliance.
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.
2005105Its 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 131 to 123 cfm. Most spec sheets show only the first number, precisely because it looks better.
63 WMeasured at the airflow it actually runs at
Its 72% at 0 °C is certified at 49 cfm, the continuous airflow of a typical home. At that setting it draws 63 W, or about 552 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 37 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. 2005105. 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.
