Outdoor unit
One compressor for the whole house. It supplies up to 6 heads and modulates from 13,000 to 36,800 BTU/h depending on what the rooms call for (NEEP).
Base pan heater
A heater keeps the outdoor unit’s base pan free of ice below 1 °C and during defrost (NEEP).
Refrigerant lines
One pair of lines per head.
Indoor heads
One head per room, each with its own remote and temperature. The combination is chosen in the “Zones” menu.
Control
Each zone is set separately.
Turn rooms on and off. Watch the power being shared.
One outdoor unit supplies every head: when several rooms call at once, they share its capacity. Pick an outdoor temperature.

A multi-zone solution designed for the residential and multi-unit realities of Longueuil
In many residential and multi-unit projects in Longueuil , we see a very clear demand: precise comfort in each room , without increasing the number of outdoor units or raising energy bills. The ELIOS E-MULTI 5-head multi-zone heat pump with a 48,000 BTU compressor perfectly meets this need. This system can power up to five independent indoor units from a single outdoor unit, while maintaining stable performance even during the harsh winters of the South Shore .
At AirGreen , we install this type of configuration in single-family homes, duplexes, newer condos, and complex renovations where outdoor space is limited. The E-MULTI series stands out for its ease of integration , its heating efficiency down to -25°C , and its eligibility for the LogisVert provincial subsidy , currently valued at $4,080 .
Why choose an ELIOS E-MULTI multi-zone heat pump in Longueuil?
One single outdoor unit, multiple perfectly controlled zones
The 48,000 BTU EXHSA4862AV1 compressor acts as the heart of the system. It distributes the necessary power to several indoor units, each independently controlled. In practical terms, this means:
-
Adjustable temperature room by room
-
Reducing temperature differences in the house
-
Effective management of actual needs, according to space occupancy
-
Less exterior clutter, a major advantage in urban environments
In several projects carried out in Longueuil and Boucherville , we replaced old electric or baseboard heating systems with this type of multi-zone configuration, with an immediate gain in comfort and a measurable decrease in energy consumption.
Winter performance adapted to the Quebec climate
The ELIOS E-MULTI heat pump is designed to maintain reliable heating capacity down to -25°C , a non-negotiable requirement for the South Shore . At -8°C , the system delivers approximately 34,000 BTUs , and maintains a capacity of 36,000 BTUs at -15°C , which allows it to cover a large portion of heating needs without systematically resorting to supplemental heating.
The COP of 12.13 at -8 °C demonstrates excellent energy efficiency: each kilowatt consumed is converted into a significantly greater amount of heat, which is directly reflected in electricity bills.
Key technical details of the ELIOS E-MULTI 48,000 BTU system
General characteristics of the outdoor compressor
-
Cooling capacity : 48,000 BTU
-
Heating capacity : down to -25°C
-
Refrigerant : R-454B , more environmentally friendly
-
ENERGY STAR® : certified, including the cold climate category
-
AHRI : 216046645
-
Voltage : 220 V
-
MOP : 45 A
-
Outdoor noise level : 65 dB(A)
These characteristics make it a relevant choice for both high-end residential projects and multi-unit buildings where stability and durability are a priority.
Compatible indoor units and installation flexibility
The system accepts a wide range of ELIOS indoor units:
-
Wall panels: EWHMA06C2AS1 to EWHMA33C2AS1
-
Ducted
-
1-channel or 4-channel cassettes
-
Consoles
This diversity allows the solution to be adapted to the building's architecture, the type of ceiling, and the occupants' aesthetic preferences. In some projects in Longueuil-East , we combined wall units in the bedrooms and a discreet cassette in the common areas, while maintaining independent control for each zone.
Silence, comfort and quality of life on a daily basis
An often underestimated point when choosing an HVAC system is the indoor noise level . Depending on the model chosen, ELIOS indoor units can operate at as low as 20 dB(A) , which is particularly appreciated in bedrooms and home offices.
During a recent installation in a condo near Michel-Chartrand Park , the client reported an immediate improvement in acoustic comfort compared to their old system, particularly during nighttime heating cycles.
Safety, reliability and R-454B technology
The E-MULTI series incorporates R-454B refrigerant leak detection . In case of a malfunction:
-
The compressor automatically stops operating
-
The indoor fan continues to circulate the air in order to reduce any potential concentration
-
A shut-off valve limits the refrigerant flow.
These measures enhance occupant safety and system longevity, an aspect we always explain in detail to our clients during installation.
LogisVert subsidy and return on investment
With a $4,080 LogisVert provincial grant , the ELIOS E-MULTI 5-head, 48,000 BTU heat pump becomes particularly attractive from a financial perspective. In several cases in Longueuil and on the South Shore , the return on investment is observed within a reasonable timeframe, thanks to:
-
To reduce the costs of electric heating
-
With central air conditioning without multiple units
-
Regarding the durability of the compressor and its components
Guaranteed peace of mind with AirGreen

What people ask us about multi-zone systems.
Can I heat one room and cool another at the same time?
No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.
What happens when every room calls for heat?
They share the outdoor unit’s capacity: 36,800 BTU/h at −8 °C, 36,000 at −15 °C.
How many heads can I connect?
Up to 6 on this outdoor unit. This product is configured for 5 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 46 combinations, from 6+6+6+6+6 to 12+12+12+12+12 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$4,416 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.
Is it ENERGY STAR certified?
Yes, cold climate, ID 3799033. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −25 °C.
Is it noisy?
Indoors, the reference head goes down to 20 dB(A). Outdoors, 65 dB(A): we place the unit away from bedroom windows.
Why a multi-zone instead of several wall units?
One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.
What does the warranty cover?
Our sheet lists 10 years on the compressor and 10 years on parts; labour is not included by the manufacturer. AirGreen extended warranty: possible.
A multi-zone system is planned room by room. At your home.
We measure every room, draw the line route and choose the right head for each zone. The on-site estimate is free and the quote arrives within 24 h.
