FANTECH VHR 150R Air Exchanger Greater Montreal
Is it the right size for your home?
It delivers 155 cfm net, enough to ventilate 1,800 to 2,900 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 155 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
$71.25
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 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 60% at 89 cfm.
Airflow and efficiency: manufacturer's published data. Cost: 73 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.
6 in oval6 in oval collars with a balancing damper
The plastic oval collars include a balancing damper and airflow measurement ports, so balancing is done at the unit. Fantech publishes a 90 to 170 cfm balancing range for this model.
SwitchLow / standby / medium switch on the unit
The VHR 150R has a three-position rocker switch (low, standby, medium) that provides continuous ventilation even without a wall control. Fantech offers ECO-Touch, EDF7, EDF1R, RTS2, RTS5 and MDEH1 controls as options.
60%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 89 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.
−21 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 176 to 155 cfm. Most spec sheets show only the first number, precisely because it looks better.
73 WMeasured at the airflow it actually runs at
Its 66% at 0 °C is measured at 85 cfm, the continuous airflow of a typical home. At that setting it draws 73 W, or about 639 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.
6 inWhat it needs on site
6 in (oval) ducts, top connection and a condensate drain. It weighs 44 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.
