GreenTek SOLACE 1.5H Air Exchanger Greater Montreal
Is it the right size for your home?
It delivers 150 cfm net, enough to ventilate 1,700 to 2,800 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 150 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
$58.56
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 63% at 72 cfm.
Airflow and efficiency at 0 °C and −25 °C: HVI directory, Section III. Cost: 60 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.
14.4 in14.4 × 14.4 in counterflow polymer core
Fresh and stale air flow in opposite directions through a thermoformed polymer core, 14.4 × 14.4 in and 12 in deep, with a limited lifetime warranty. Greentek's PREMIER and PROFILE series use a cross-flow core instead.
2 mountsWall or hanging install: bracket and chains included
The SOLACE 1.5H ships with a wall bracket and a hanging chain kit, so it can be fixed to a wall or hung from the ceiling, depending on the room available in the mechanical space.
63%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 72 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.
2505386Its 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.
−17 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 167 to 150 cfm. Most spec sheets show only the first number, precisely because it looks better.
60 WMeasured at the airflow it actually runs at
Its 80% at 0 °C is certified at 72 cfm, the continuous airflow of a typical home. At that setting it draws 60 W, or about 526 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 ducts, top connection. It weighs 52 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. 2505386. 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.

Greentek's Solace 1.5H HRV is designed to tackle the ventilation requirements of tightly sealed modern homes. While natural infiltration through gaps and cracks in the building envelope does provide a certain amount of fresh air, it is often not sufficient for well-insulated homes. Mechanical ventilation is needed to remove excess moisture, odors, and contaminants while ensuring fresh air supply for occupants.
The Solace 1.5H provides a controlled way of ventilating a home. This HRV is capable of recovering up to 80% of the heat in the extracted air, using it to warm the fresh air drawn from the outside. In the summer, the energy from the extracted air cools the incoming warmer fresh air, reducing the load on air conditioning.
The Solace 1.5H comes equipped with a wall mount, external electrical box with easy-connect ports, integrated in-door manometer ports, and duct ports with plastic collar shrouds and integrated backdraft for a simple and fast installation. It also includes chains for easy mounting, making it a versatile addition to any home ventilation system.
The Solace series also offers recirculation defrost, making it ideal for high-humidity indoor conditions or colder outdoor climates. Its innovative counterflow core design offers more efficiency than existing crossflow technologies, and the entire Solace series is top-port designed to fit in tight spaces.
Pair the Solace 1.5H with the Greentek STS 2.0 Controller for seamless remote operation. Its key features, including round metal duct connections with rubberized duct seals, a removable screw terminal for easy connection with external access, and energy-efficient motors, further enhance the user experience.
In conclusion, the Greentek Solace 1.5H HRV delivers an efficient, comfortable, and quiet ventilation solution for homes of the future. With its advanced technology and design, it delivers superior performance that is in line with Greentek's commitment to enhancing indoor air quality and home comfort.
