FANTECH VHR 100R ES Air Exchanger Greater Montreal
Is it the right size for your home?
It delivers 104 cfm net, enough to ventilate 1,200 to 1,900 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 104 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
$62.47
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 58% at 66 cfm.
Airflow and efficiency: manufacturer's published data. Cost: 64 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.
70–110Balanced airflow of 70 to 110 cfm, set at the collars
The 5 in oval collars include a balancing damper and airflow measurement ports. Fantech publishes a 70 to 110 cfm balancing range; outside it, the maker recommends choosing another model.
24 inInstalls in a space as small as 24 in
Thanks to its top ports and the included EZ-Mount wall bracket, Fantech says this mid-range HRV fits in a space as small as 24 in, such as a closet or maintenance room.
58%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 66 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.
HRVIt recovers heat, not moisture
Excess moisture leaves the house. In Québec, that's the right choice in most cases: in winter, the problem is almost always too much humidity, not too little.
−18 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 122 to 104 cfm. Most spec sheets show only the first number, precisely because it looks better.
64 WMeasured at the airflow it actually runs at
Its 61% at 0 °C is measured at 63 cfm, the continuous airflow of a typical home. At that setting it draws 64 W, or about 561 kWh a year.
LifetimeThe core warranty
The core does the work and is the most expensive part to replace. Motors: 7 years. Parts: 5 years. We register the warranty in your name at commissioning.
5 inWhat it needs on site
5 in (oval) ducts, top connection and a condensate drain. It weighs 39 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.
