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.
