As soon as the temperature dropped below -10 °C, baseboard heaters took over again. The \u003cstrong\u003eDURASTAR Sirius Heat Wall-Mounted Heat Pump | 24,000 BTU - R454B\u003c\/strong\u003e changes that equation for large living areas: its AHRI certificate rates it at \u003cstrong\u003e24,000 BTU\/h at -15 °C\u003c\/strong\u003e, meaning its full nominal capacity at a temperature that occurs several times each winter in Greater Montreal.\u003c\/p\u003e\u003cp\u003eIts certified ratings are \u003cstrong\u003e22.3 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.5 EER2\u003c\/strong\u003e and \u003cstrong\u003e13.3 HSPF2\u003c\/strong\u003e.

DuraStar's commercial sheet lists 21,600 BTU\/h at -8 °C; we use the certified value of 23,000 BTU\/h because that is the figure used by ENERGY STAR and Hydro-Québec. A COP of 2.00 at -15 °C means the unit delivers two units of heat for every unit of electricity consumed, whereas a baseboard heater delivers only one.\u003c\/p\u003e\u003ch3\u003eA primary heat source, with a plan for the coldest nights\u003c\/h3\u003e\u003cp\u003eWith these figures, the heat pump can handle most of the heating for the area it serves during most of the season, not just in the fall. We still present it with a clear plan for extreme conditions. Below -15 °C, capacity gradually decreases, reaching 10,900 BTU\/h at -30 °C. Existing baseboard heaters, or an electric furnace already installed, therefore remain connected and set a few degrees below the heat pump's setpoint. They start only when the unit is no longer sufficient, which occurs mainly during cold snaps.\u003c\/p\u003e\u003cp\u003eA wall-mounted unit heats from a single point. It is highly effective in a large open area, but much less so in closed bedrooms at the end of a hallway. For sizing, we start at approximately 18,000 BTU\/h per 1,000 square feet, then adjust according to ceiling height, windows, orientation and insulation quality. A 24,000 BTU unit is therefore suited to open ground floors, large finished basements and through-units where air can circulate easily from one end to the other.\u003c\/p\u003e\u003ch3\u003eCooling a large space\u003c\/h3\u003e\u003cp\u003eIn summer, the system delivers 23,000 certified BTU\/h, with a seasonal efficiency rating of 22.3 SEER2. Modulation ranges from 16,800 to 24,500 BTU\/h. For rooms with extensive south- or west-facing windows, this reserve makes it possible to quickly offset heat accumulated late in the day. The \u003cstrong\u003eECO\/GEAR\u003c\/strong\u003e function then limits consumption in cooling mode, while Turbo mode is useful when returning home after a hot day.\u003c\/p\u003e\u003ch3\u003eLogisVert: $2,760 for this system\u003c\/h3\u003e\u003cp\u003eThe system is registered with the \u003cstrong\u003eLogisVert\u003c\/strong\u003e program under \u003cstrong\u003eENERGY STAR ID 3621160\u003c\/strong\u003e, with a \u003cstrong\u003e$2,760 rebate\u003c\/strong\u003e for owners of existing homes. An enhanced rebate applies to certain multi-unit residential buildings. The amount depends on the list in effect on the installation date; we confirm it before signing and provide the detailed invoice, model numbers and required proof of payment.

Three factors determine whether the project is feasible and how much it will cost. We check all of them during the in-home assessment.\u003c\/p\u003e\u003ch3\u003e1. The electrical circuit\u003c\/h3\u003e\u003cp\u003eThe system requires a \u003cstrong\u003e208-230 V\u003c\/strong\u003e supply, an \u003cstrong\u003eMCA of 25 A\u003c\/strong\u003e and a \u003cstrong\u003e25 A circuit breaker\u003c\/strong\u003e on a dedicated circuit. A 200 A electrical panel often has enough capacity. In an older home where a 100 A service already supplies baseboard heaters, a water heater and a range, we perform a load calculation before proposing anything.\u003c\/p\u003e\u003ch3\u003e2. The structure supporting the outdoor unit\u003c\/h3\u003e\u003cp\u003eThe condenser measures \u003cstrong\u003e37.24 x 16.14 x 31.89 inches\u003c\/strong\u003e and weighs \u003cstrong\u003e130.3 pounds\u003c\/strong\u003e. At this weight, we favour a ground stand on a stable base or a wall bracket anchored to the building structure, such as brick or concrete, rather than only to the siding. The unit must remain above the snow line and protected from roof runoff. Its sound level of \u003cstrong\u003e61 dB(A)\u003c\/strong\u003e also requires keeping it away from bedroom windows, including neighbours' windows, which matters greatly in dense \u003cstrong\u003eMontreal\u003c\/strong\u003e neighbourhoods. The base-pan heater and fin corrosion-resistant coating are included.\u003c\/p\u003e\u003ch3\u003e3. Clearances and line routing\u003c\/h3\u003e\u003cp\u003eThe refrigerant lines are \u003cstrong\u003e3\/8 and 5\/8 inch\u003c\/strong\u003e. They are precharged for 25 feet and can reach \u003cstrong\u003e164 feet\u003c\/strong\u003e, with a maximum elevation difference of \u003cstrong\u003e82 feet\u003c\/strong\u003e. Beyond the precharged length, 0.32 ounces of refrigerant is added per foot. This length makes it possible to place the condenser in the least conspicuous location on the property, even far from the indoor unit. The 5\/8-inch diameter matters if you want to reuse existing lines: they must match the system, and cleaning and testing them are then included. Our installations remain fully exposed, with no opening of interior walls, and a finished line-set cover can be added as an option. The indoor unit also requires sufficient clearance from the ceiling and on the sides for airflow and servicing.\u003c\/p\u003e\u003ch3\u003eThe indoor unit\u003c\/h3\u003e\u003cp\u003eThe wall-mounted unit measures \u003cstrong\u003e42.60 x 9.21 x 13.27 inches\u003c\/strong\u003e and weighs 30.8 pounds.

Like any \u003cstrong\u003eR-454B\u003c\/strong\u003e system, which uses an A2L refrigerant with low global warming potential, the unit includes a factory-installed leak detector.
