vänEE 40E Air Exchanger | Montreal, Laval, Longueuil, South Shore and North Shore
Is it the right size for your home?
It delivers 70 cfm net, enough to ventilate 800 to 1,300 sq ft. Choose your home's living area.
It's the right size.
For a 900 to 1,500 sq ft home, about 63 cfm of air needs to be renewed continuously. This unit delivers 70 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
$33.19
Electricity per year
Less than a 60 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 56% at 36 cfm.
Airflow and efficiency: manufacturer's published data. Cost: 34 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.
16 5/16 inSide ports keep the height to 16 5/16 in
The 44263 is the 40E version with 4-in ports on the sides: 16 5/16 in high, versus 18 5/8 in for the top-port version (44262). Plan instead for 19 13/16 in of width.
On holdDefrost steps aside when ventilation is called for
The 40E does not defrost above −5 °C. If an auxiliary wall control calls for ventilation during a cycle, defrost is put on hold while air is exchanged, so humid air is not recirculated.
56%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 36 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.
−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 78 to 70 cfm. Most spec sheets show only the first number, precisely because it looks better.
34 WMeasured at the airflow it actually runs at
Its 66% at 0 °C is measured at 36 cfm, the continuous airflow of a typical home. At that setting it draws 34 W, or about 298 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.
4 inWhat it needs on site
4 in ducts, side connection. It weighs 34 lb, and it needs enough clearance to slide the core out once a year.
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.
