ZEPHYR CB22 wall-mounted heat pump · updated October 9, 2026

Zephyr CB22 wall-mounted heat pump: R-32, from 9,000 to 24,000 BTU/h.

The R-32 CB22 heats down to -25 °C and cools from -15 to 48 °C, per Zephyr. Four sizes on 208/230 V and two on 115 V (DB22). It is ENERGY STAR standard certified at 9,000 and 18,000; the 18,000 qualifies for $740 of LogisVert. Our advice: best for cooling and shoulder-season heating.

04 · Efficiency

1 kWh of electricity, how much heat?

The first panel gives the COP of each CB22 at +8.3 and -15 °C; the second, the electricity needed to cool a season based on each size’s SEER2.

Each bar starts from 1 kWh of electricity. Each segment = 1 kWh of heat delivered (the COP).

Illustrative math: SEER2 is, by definition (DOE, Appendix M1), the heat removed over the season divided by the electricity used, in BTU per watt-hour. Cost at Hydro-Québec’s Rate D second-tier price (11.142¢/kWh since April 1, 2026), which applies if use exceeds the first tier (40 kWh per day, times the number of days in the period); below it, a kWh costs 7.065¢. Before taxes and access fees. Your home will have its own numbers.

11 · Warranty and installation

10 years on parts, a 6-year legal warranty.

Zephyr’s base warranty covers the CB22’s parts for 10 years. For a heat pump bought new on or after October 5, 2026, the law adds a 6-year warranty of good working order, counted from delivery.

Zephyr base warranty
10 years

on parts, per the CB22 BRO_2606 brochure and TTI page. “A labour warranty is available”: ask your contractor.

Parts (Zephyr)
10 years
Legal warranty
6 years

For a heat pump or air conditioner bought new from a merchant on or after October 5, 2026, Quebec law adds a free, automatic 6-year warranty of good working order, counted from delivery (Office de la protection du consommateur). Under TTI’s parts policy (v3.4, July 17, 2026), labour to replace a part during that period falls on the installing contractor.

Certified technician

Service or repair by anyone not certified and authorized by TTI (or Kinghome) ends the manufacturer’s conventional warranty (TTI, s. 4.4).

Through your installer

If something breaks, you call the contractor who installed it; they file the claim with TTI.

Filters, every month

TTI’s policy asks owners to clean the indoor unit filters at least once a month (s. 6.3).

What people ask us about the CB22.

It heats down to -25 °C per Zephyr, with no capacity published at -25 °C. For main heating all winter, we recommend the CB25 or UB32 instead, which run in heating mode down to -30 °C per Zephyr.
