Questions
Questions about the 6-head ELIOS systems.
Six heads, is it really a good idea?
The ELIOS table allows it, but six rooms share 36,800 BTU/h certified at −8 °C. For a large cold house, two systems may do better: we compare both options.
Can a 24,000 go in a 6-head system?
No: the table’s 34 six-head combinations stop at 18,000 heads.
How much space does the outdoor unit take?
About 952 mm wide, 415 mm deep and 1,333 mm high, per the ELIOS submittal, plus clearance and elevation for snow.
What happens if a head detects a leak?
The head’s fan runs to disperse the refrigerant, an automatic shut-off valve isolates the circuit and the compressor stops, per the 2026 e-Multi brochure.
What warranty on an e-Multi?
ELIOS publishes 1 year on parts and 5 years on the compressor, with optional 10-year coverage. ELIOS publishes no labour warranty.
