A multi-zone solution designed for the demanding buildings of the South Shore

In a residential and semi-commercial context where heating and cooling needs vary greatly from room to room, the ELIOS E-MULTI 4-head heat pump with a 48,000 BTU compressor stands out as a structured, reliable HVAC solution perfectly suited to the realities of Longueuil , the South Shore , Montreal , Laval and peripheral areas subject to harsh winters.

At AirGreen , we regularly install this type of multi-zone system in large single-family homes, duplexes, renovated triplexes, as well as in multi-unit buildings where independent comfort management by zone is desired, without multiplying outdoor units.

Understanding the ELIOS E-MULTI logic: a single outdoor unit, multiple controlled zones

The principle of the ELIOS E-MULTI multi-zone heat pump is based on a single central compressor, here with a nominal capacity of 48,000 BTU , capable of simultaneously supplying up to four indoor units , with a technical possibility of going up to six zones depending on the configuration chosen.

Each indoor unit operates independently: temperature, operating mode, airflow, and schedules can be adjusted room by room. This approach is particularly relevant in Longueuil residences where sunlight, occupancy, and room sizes vary significantly between floors, living areas, and bedrooms.

Compatible indoor unit types

One of the major advantages of the ELIOS E-MULTI range is its compatibility with several indoor unit formats:

• Wall-mounted units (6,000 to 24,000 BTU)

• Ducted units for discreet distribution

• 4-way cassettes for suspended ceilings

• 1-track cassettes

• Consoles

At AirGreen, we often combine several formats in the same project, for example wall units in bedrooms and a cassette or ducted unit in open areas.

Actual performance in Quebec climate

The EXHSA4862AV1 outdoor unit, associated with this system, is designed to operate efficiently down to -25°C , an essential factor for the winters of Montérégie and the South Shore.

Key performance data

• Cooling capacity : 48,000 BTU

• Nominal heating capacity : up to 48,000 BTU

• Available power at -8°C : approximately 34,000 BTU

• Available power at -15°C : approximately 36,000 BTU

• COP at -8 °C : 2.13

These values ​​reflect a real ability to maintain stable comfort without excessive use of supplementary heating sources, which is a crucial point for customers wishing to reduce their dependence on electric baseboard heaters.

Energy efficiency and compliance with standards

The ELIOS E-MULTI 48,000 BTU heat pump is ENERGY STAR® certified, including for cold climates, making it eligible for the LogisVert provincial grant , currently estimated at $4,080 for this model, subject to current conditions.

Seasonal efficiency indices demonstrate a design geared towards energy savings:

• SEER2 (air conditioning): up to 21.3 depending on the configuration

• HSPF2 (heating): up to 8.1

• EER2 : up to 11.7

In practice, this translates into a measurable reduction in annual consumption, particularly in residences where several areas were previously heated uniformly and inefficiently.

R-454B refrigerant: a responsible and future-proof choice

This system uses R-454B refrigerant , a gas with a lower global warming potential than previous generations. For our environmentally conscious clients in Longueuil and Montreal, this choice allows us to reconcile thermal performance with regulatory compliance.

The ELIOS E-MULTI range also incorporates refrigerant leak detection devices, with automatic compressor shutdown and safety ventilation, an often underestimated but essential aspect in modern multi-zone installations.

HVAC installation: AirGreen's expertise makes the difference

Installing a 48,000 BTU multi-zone heat pump involves more than just connecting refrigerant lines. At AirGreen , each project is:

• a complete thermal analysis of the building

• a precise calculation of charges per zone

• from a rigorous selection of indoor units

• careful planning of pipe routes

• of an electrical check (MCA, MOP, 45 A circuit breaker)

In Longueuil, for example, we installed this model in an intergenerational residence where the heating needs of the basement differed significantly from those of the main floor. Poor capacity distribution would have led to discomfort and excessive cycling. The E-MULTI solution, properly configured, ensured consistent thermal stability throughout the entire building.

Acoustic comfort and discreet integration

Despite its power, the outdoor unit has a noise level of approximately 65 dB(A) , which meets the urban requirements of the South Shore. Depending on the model, the indoor units can operate as quietly as 20 dB(A) in quiet mode, a crucial factor for bedrooms and home offices.

Aesthetic integration is also an important criterion: controlled dimensions, clean lines, and installation options adapted to the architectural constraints of Longueuil houses and dense residential areas.

Guarantee and peace of mind

The standard configuration includes a 10-year warranty on the compressor and 10-year warranty on parts (subject to registration), with the option to add an extended labor warranty through AirGreen. This approach helps eliminate unpleasant surprises in the long term, especially for more complex multi-zone systems.
