Air Exchanger VENMAR AVS® X SERIES X30ERVE Greater Montreal
Is it the right size for your home?
It delivers 244 cfm net, enough to ventilate 2,900 to 4,600 sq ft. Choose your home's living area.
It's the right size.
For a 3,200 to 5,000 sq ft home, about 215 cfm of air needs to be renewed continuously. This unit delivers 244 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
$17.57
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 everywhere in the province. 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 65% at 64 cfm.
Airflow and efficiency: manufacturer's published data. Cost: 18 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.
27 inPlan 27 in of clearance in front of the door
The guide calls for 27 in of free space in front of the unit so the door can open. An 18 in clearance is acceptable, but the door must then be removed for each maintenance: plan for it in a tight mechanical room.
18–40 °CInstall in a conditioned space, 18 to 40 °C
The guide requires a conditioned space kept between 18 and 40 °C with at most 60% relative humidity. An unheated attic, garage or crawl space is therefore not suitable for this unit.
65%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 64 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.
−15 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 259 to 244 cfm. Most spec sheets show only the first number, precisely because it looks better.
18 WMeasured at the airflow it actually runs at
Its 75% at 0 °C is measured at 64 cfm, the continuous airflow of a typical home. At that setting it draws 18 W, or about 158 kWh a year.
10 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.
6 inWhat it needs on site
6 in (oval) ducts, top connection. It weighs 96 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.
