LIFEBREATH RNC4-TPD Air Exchanger Greater Montreal
Is it the right size for your home?
It delivers 59 cfm net, enough to ventilate 700 to 1,100 sq ft. Choose your home's living area.
It's the right size.
For a condo or a home under 900 sq ft, about 37 cfm of air needs to be renewed continuously. This unit delivers 59 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
$36.11
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 51 cfm.
Airflow and efficiency at 0 °C and −25 °C: HVI directory, Section III. Cost: 37 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.
CompactLifebreath's smallest unit to date
Lifebreath presents it as its smallest unit to date, built for small homes and townhomes with tight space. It hangs from the supplied S hooks and straps, which attach to four threaded inserts at the cabinet corners.
MERV 13Washable MERV 6 filters, MERV 13 upgrade
It ships with washable MERV 6 filters in both the exhaust and supply airstreams. For finer filtration, Lifebreath offers a MERV 13 upgrade (part 65-195-6R).
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 51 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.
2505248Its 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.
−11 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 70 to 59 cfm. Most spec sheets show only the first number, precisely because it looks better.
37 WMeasured at the airflow it actually runs at
Its 63% at 0 °C is certified at 47 cfm, the continuous airflow of a typical home. At that setting it draws 37 W, or about 324 kWh a year.
LifetimeThe 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, top connection and a condensate drain. It weighs 35 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. 2505248. 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.
