ZEPHYR CB25 wall-mounted heat pump · updated October 9, 2026

Zephyr CB25 wall-mounted heat pump: down to -30 °C, from 9,000 to 24,000 BTU/h.

The R-454B CB25 heats down to -30 °C per Zephyr, with an electronic expansion valve and ENERGY STAR cold-climate certification. Four sizes on 208/230 V, and two on 115 V (DB25). Like the CB22, it goes up to 24,000 BTU/h, but it is the only one of the two to heat down to -30 °C, and it qualifies for the largest LogisVert amount of any Zephyr wall unit: $2,640.

04 · Efficiency

1 kWh of electricity, how much heat?

The first panel gives the COP of each CB25 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).

11 · Warranty and installation

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

Zephyr’s base warranty covers the CB25’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 CB25 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).
