ELIOS wall heat pumps · Greater Montreal

Choose an ELIOS wall unit by the winter it has to get through.

Two R-454B lines are sold today: EMC heats and cools down to −30 °C, EBC covers the essentials down to −20 °C (−25 °C on the 30,000 and 36,000). The five older R-410A series stay on this page for anyone who already has one at home.

Everything to know

Everything the ELIOS wall unit documents say when you read them together.

All 35 listings in one table, NEEP-certified cold data, noise on the Québec.ca scale, and what changed from R-410A to R-454B.

Every model, side by side

All 35 ELIOS wall units, grouped by series.

One row per listing. The e19, e23 and three e21 series have no NEEP record: their certified cells stay empty rather than filled at random.

Refrigerant

R-454B or R-410A: what the change means at home.

R-454B · EMC and EBC

The refrigerant in the ELIOS wall units sold today. It is classed A2L (mildly flammable): that is why every EMC has a leak sensor that stops the compressor and runs the fan, and why the EBC 30,000 and 36,000 get one from July 2026 production. ELIOS’s June 19, 2026 bulletin announces R-454B phasing in over 2025-2026.

R-410A · e19 to e28

The refrigerant in the older wall series. The same ELIOS bulletin announces its phase-out in 2026. An R-410A heat pump already installed keeps running and can be repaired; the two refrigerants are never mixed in one system.

Questions

The questions we get about ELIOS wall units.

EMC or EBC: which one for Montreal?

If the unit has to heat the room all winter, EMC: it heats down to −30 °C per ELIOS and keeps more capacity in the cold (12,000: 11,500 BTU/h at −15 °C versus 8,000 for the EBC). If it mostly cools and heats as a backup, the EBC does the job with less capacity.

Are the e19, e21, e23, e25 and e28 still sold?

They are R-410A series that ELIOS’s June 2026 bulletin replaces with EMC and EBC. We keep their pages for owners. Availability of a unit is confirmed at the time of the quotation.

Can an ELIOS wall unit plug into a 115 V outlet?

Only one current wall unit does: the EBC 12,000 in 115 V (20 A maximum fuse). The other EMC and EBC models are 208-230 V.

What warranty does ELIOS give on its wall units?

ELIOS publishes 1 year on parts and 5 years on the compressor, with optional 10-year parts and compressor coverage. ELIOS publishes no labour warranty.

Which ELIOS wall unit gets the most LogisVert grant?

On Hydro-Québec’s list of Oct. 25, 2026, the EMC 33,000: $3,720. The 9,000 models are not on it, since the outdoor unit must be at least 12,000 BTU/h.

Why do some older wall units show no cold-weather figure?

Because their AHRI number leads to no NEEP record. Rather than invent, we leave the cell empty. The ELIOS brochures for these series only publish their operating range (−20 or −25 °C).

Can an EMC be a head on a multi-zone system?

Yes: ELIOS uses the same EMC wall units as heads on its R-454B e-Multi systems. See the ELIOS multi-zone page.

Does the outdoor unit need to be raised?

Yes, in heating use: ELIOS asks for 30.5 to 61 cm (12 to 24 in) above the ground, for snow and defrost water. We plan for it in the quotation.
