ELIOS e28 wall unit · previous generation
The e28 already heated at −30 °C on R-410A. Its replacement, the EMC, does the same on R-454B.
Two sizes, 12,000 and 18,000, only offered in the Quebec market per the 2024 ELIOS brochure: heating down to −30 °C, a full 18,000 BTU/h at −15 °C on the 18,000. ELIOS’s June 2026 bulletin replaces it with the EMC.

Refrigerant
R-410A today, R-454B tomorrow: what it changes for your e28.
Your e28: R-410A
It keeps running and is repaired with R-410A. ELIOS’s June 19, 2026 bulletin announces the phase-out of R-410A in 2026 for new equipment.
The replacement: R-454B
The EMC and EBC use R-454B, classed A2L. The two refrigerants are never mixed: a replacement is a complete system, after checking the existing lines.

Questions
Questions about the ELIOS e28 wall unit.
Is the e28 still sold?
It is an R-410A series that ELIOS’s June 2026 bulletin replaces with the EMC. Availability of a unit is confirmed at the time of the quotation.
Does my e28 qualify for LogisVert?
The 12,000 ($1,200) and the 18,000 ($1,800) are on the Oct. 25, 2026 list. The grant applies to a new installation, within 9 months; have Hydro-Québec confirm your case.
Which EMC replaces my e28 12,000?
The EMC 12,000 is the equivalent size: 12,000 BTU/h certified at −8 °C versus 10,000 for the e28. We confirm the size on site.
Can the e28 lines be kept?
The refrigerant changes (R-410A to R-454B). We check the condition, sizes and length of the existing lines before proposing to reuse them.
What warranty did the e28 have?
The brochure publishes 1 year on parts and 5 years on the compressor, with optional 10-year coverage.
My e28 frosts up outside: is that normal?
In heating, every heat pump frosts and defrosts in cycles; the e28’s heated base pan clears the water. If ice builds up without melting, call us.
