It's the right size.
For a 900 to 1,500 sq ft house, it's within its range. It will run at part load on ordinary days and keep a reserve for the coldest days.
Area published by Lennox for an average-construction home with 8 ft ceilings. For a very tight home, Lennox gives 4,200 sq ft. Older or leaky house: go one size up; our estimator confirms it on site.
What it does, in numbers
Output: manufacturer's spec (18 gal/day, with 49 °C (120 °F) furnace air).
What you should know about this one
Published, verifiable figures, not brochure claims.
18 galWhat it produces per day, at full output
About 68 litres of water turned into humidity in 24 hours. The control runs it to match the humidity you set: it rarely runs flat out, except in very cold weather.
Heat pumpBehind a heat pump, it produces less
It evaporates water from a pad using the heat of the air coming off the furnace. A heat pump blows cooler air, so it evaporates less. With a heat pump, talk to our estimator: depending on the manufacturer, we connect it to hot water or suggest a steam model instead.
0 ductNo bypass duct
Thermally protected 120 V motor (0.8 A). Needs a 14¾ × 14 5/16 in. opening in the plenum.
Hot waterOn the return or with a heat pump
Mounted on the return, or with a heat pump, Lennox requires hot water (140 °F max).
VerticalNot on a horizontal duct
Lennox doesn't allow it on a duct where the air flows horizontally.
ControlThe control that comes with it
Mechanical manual humidistat (15 to 50% range), on the wall or the return duct.
UpkeepWhat gets replaced, and when
Healthy Climate X2661 (#35) water panel, replace once a year.
35%The humidity to aim for in winter, at most
At −7 °C, no more than 35%; at −18 °C, no more than 25%. Above that, the moisture condenses on the windows. The control adjusts for you if it has an outdoor sensor.
5 yearsThe parts warranty
Parts are covered for 5 years by the manufacturer. We register the warranty in your name at start-up.
What it needs on site
Our estimator checks the ducts, the water supply and the drain before ordering.

Healthy Climate HCWP3-18: Lennox's fan-powered model, no bypass duct
The HCWP3-18 is the fan-powered humidifier of the Healthy Climate line. It puts out 18 gal/day with 120 °F (49 °C) furnace air and covers up to 2,100 sq ft according to the manufacturer, for an average-construction home with 8 ft ceilings.
What sets it apart
A thermally protected 120 V motor (0.8 A) pushes air through the pad: no bypass duct to install. It uses the same X2661 (#35) water panel as the HCWB3-17. With no letter, it ships with the mechanical manual humidistat, adjustable from 15 to 50%, on the wall or the return duct; the HCWP3-18A has an automatic control with outdoor sensor instead.
What it needs on site
Plan for a 14¾ × 14 5/16 in. opening in the plenum, a 120 V outlet, a water supply and a drain; it takes in about 6 gal of water an hour. Lennox doesn't allow it on a duct where the air flows horizontally. Mounted on the return, or with a heat pump, it must be fed hot water, 140 °F (60 °C) at most. The pad is replaced once a year.
Our crew installs it
Our technicians install the HCWP3-18 from start to finish. An estimator first comes to check the furnace, the electrical panel, the water and the drain, then gives you a quote for the installed unit. Montréal, Laval, Longueuil, South Shore and North Shore: 514 316-2973.
