Outdoor unit
One compressor for the whole house. It supplies up to 5 heads and modulates from 10,000 to 31,000 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.
Tell us your rooms. We tell you if this size is enough.

A multi-zone solution designed for Quebec's climate and the realities of local housing.
At AirGreen , we've been installing multi-zone systems for years in Laval , Montreal , Longueuil , and on both the North and South Shores . The ELIOS E-MULTI 2-head heat pump with a 36,000 BTU compressor is a clear and logical choice for homeowners who want to heat and cool multiple rooms without needing multiple outdoor units. This model addresses very real constraints we encounter in the field: limited outdoor space, reliable heating down to -25°C , measurable energy efficiency, and flexible interior design.
Why the E-MULTI 2-head format makes a difference in a residential project
In many projects in Laval and on the Island of Montreal , single-family homes, duplexes, and condos feature distinct thermal zones: main floor, upstairs bedrooms, and a partially finished basement. Installing two independent systems may seem logical, but it complicates maintenance, increases the exterior footprint, and raises the overall cost.
The ELIOS E-MULTI multi-zone heat pump allows you to connect two indoor units (and up to five zones on the platform) to a single 36,000 BTU outdoor compressor . In practical terms, this means:
-
independent temperature control in each room,
-
a more discreet outdoor installation
-
an optimization of overall energy efficiency,
-
improved aesthetic consistency, particularly appreciated in urban environments.
Actual heating and air conditioning performance
One of the points that concerns us, as HVAC installers, is consistent performance under demanding conditions. The ELIOS E-MULTI 36,000 BTU is designed to operate efficiently in heating mode down to -25°C , a crucial value for the climate of Laval and the North Shore .
Key data observed in the field
-
Rated capacity : 36,000 BTU
-
Power at -8°C : approximately 27,000 BTU
-
Power at -15°C : approximately 26,000 BTU
-
COP at -8°C : 12.03 , which translates to stable energy efficiency even in cold weather
-
Outdoor noise level : 63 dB(A) , compliant with current residential standards
These characteristics are confirmed in the installations we have carried out, particularly in multi-story houses where the demand for heating is sustained for several months of the year.
A modern refrigerant: R-454B and its practical implications
The choice of R-454B refrigerant is not insignificant. This refrigerant, with its lower environmental impact, is gradually replacing older gases while maintaining excellent thermal performance. In practice, this means:
-
improved compliance with current environmental standards,
-
Enhanced safety thanks to integrated leak detection and automatic operating management systems,
-
a more sustainable solution for owners who wish to invest for the long term.
During our AirGreen installations, we pay particular attention to the ventilation of spaces and to respecting clearances, so that these devices work exactly as intended.
Wide compatibility of indoor units: a real design advantage
The ELIOS E-MULTI platform accepts several types of indoor units:
-
wall units (6,000 to 24,000 BTU),
-
Ducted units , ideal for more discreet integration.
-
4-way cassettes for ceilings,
-
1-channel cassettes or consoles depending on the room configuration.
In a recent project in Laval-des-Rapides , we combined a 12,000 BTU wall unit in the main living area with a compact cassette unit in a bedroom located under a low ceiling. This flexibility allowed us to meet the architectural constraints without compromising comfort.
Energy efficiency and LogisVert subsidy
With ENERGY STAR® and ENERGY STAR® – Cold Climate certifications, the ELIOS E-MULTI 36,000 BTU heat pump is eligible for the LogisVert provincial grant , currently valued at $3,240 . For many customers, this factor directly influences their final decision.
At AirGreen , we systematically support our clients in:
-
validation of eligibility,
-
the preparation of the required documents,
-
coordination between the installation and the grant application.
This approach reduces delays and avoids the frequent errors we see when procedures are carried out without support.
HVAC installation: technical points not to be overlooked
A high-performance multi-zone heat pump remains dependent on the quality of its HVAC system . For this specific model, certain elements are critical:
-
appropriate electrical sizing (220 V, MOP: 35 A ),
-
compliance with maximum pipe lengths,
-
precise balancing of loads between the two zones,
-
Strategic positioning of the outdoor unit to limit the transmission of vibrations.
In several corrective interventions we carried out in Longueuil , the problems observed did not stem from the machine itself, but from poor initial planning. This is precisely where AirGreen's field experience makes all the difference.
Guarantee and peace of mind
The ELIOS E-MULTI model comes with a basic 10-year warranty on the compressor, 10 years on parts, and 0 years on labor , with the option to extend. We always clearly explain the actual scope of these warranties to our customers, including what is and isn't covered in the event of a service call or diagnostic.
This transparency avoids misunderstandings and contributes to a long-term relationship of trust.

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: 31,000 BTU/h at −8 °C, 26,000 at −15 °C.
How many heads can I connect?
Up to 5 on this outdoor unit. This product is configured for 2 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 10 combinations, from 6+18 to 18+18 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$3,720 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 3799030. 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, 63 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.
