Each baseboard warms its own stretch of wall, under its own window, with its own thermostat, and the space stays uneven. The \u003cstrong\u003eWall-Mounted Heat Pump ARCOAIRE Duracomfort | 18,000 BTU - R454B\u003c\/strong\u003e treats the open area as a whole, with a single wall head that circulates the air of the entire room.\u003c\/p\u003e\n\u003cp\u003eIts certified ratings are \u003cstrong\u003e21.5 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.5 EER2\u003c\/strong\u003e and \u003cstrong\u003e11.0 HSPF2\u003c\/strong\u003e.

The kitchen one stops when the oven is on, the living-room one runs non-stop under the big window, and the warm air from all of them rises to the ceiling. The result is familiar: warm spots, cool spots and a cold floor. A well-placed \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e spreads heat from a single point, at low airflow, and the \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e adjusts its output to the demand of the entire space.\u003c\/p\u003e\n\u003ch3\u003eFull capacity at -8 °C and at -15 °C\u003c\/h3\u003e\n\u003cp\u003eThe certificate lists \u003cstrong\u003e18,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), about 100% of nominal capacity, with a \u003cstrong\u003eCOP of 2.55\u003c\/strong\u003e, and \u003cstrong\u003e18,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), also about 100%, with a \u003cstrong\u003eCOP of 1.92\u003c\/strong\u003e. The two points are measured separately; we report each one as published.\u003c\/p\u003e\n\u003cp\u003eThis is the pairing's strong point: capacity does not drop between an ordinary cold day and real January cold. For a well-insulated open area, the heat pump can take on the main heating for nearly the whole winter, with a COP of 1.92 at -15 °C, where a baseboard is limited to one unit of heat per unit of electricity. The circuit uses \u003cstrong\u003eR-454B\u003c\/strong\u003e refrigerant, from the new generation, with a much lower global warming potential than the previous one.\u003c\/p\u003e\n\u003ch3\u003eWhat an 18,000 BTU\/h head covers, and what it does not\u003c\/h3\u003e\n\u003cp\u003eA nominal capacity of \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e typically suits a good-sized open kitchen-dining-living area, on the ground floor of a cottage, a semi-detached house or a large condo. Air circulates well as long as the space is truly open: no solid partition between the head and the far end of the room, no long hallway to cross.\u003c\/p\u003e\n\u003cp\u003eIt does not, however, cover closed bedrooms or the upper floor of a house. Some heat rises through an open staircase, but not enough to heat bedrooms whose doors stay closed. Those rooms keep their baseboards or get their own heads. We discuss this during the visit, floor plan in hand, before proposing anything.\u003c\/p\u003e\n\u003ch3\u003eAt -30 °C, the heat pump still heats\u003c\/h3\u003e\n\u003cp\u003eThe certificate publishes the maximum capacity at \u003cstrong\u003e-30 °C\u003c\/strong\u003e (-22 °F): \u003cstrong\u003e8,000 BTU\/h\u003c\/strong\u003e, about 44% of nominal capacity, with a \u003cstrong\u003eCOP of 1.20\u003c\/strong\u003e. On those exceptional nights, the heat pump keeps delivering more heat than it consumes in electricity, but the baseboards take on part of the work. The ENERGY STAR \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e confirms that the pairing was evaluated for this climate.\u003c\/p\u003e\n\u003cp\u003eIn cold, humid weather, frost forms on the outdoor unit. The heat pump then pauses heating for a few minutes for a defrost cycle; the white vapour that rises from it is normal.\u003c\/p\u003e\n\u003ch3\u003eGetting baseboards and heat pump to work together\u003c\/h3\u003e\n\u003cp\u003eIn an open area, there are often three or four baseboards, each with its own thermostat. The recommended setting is the same for all of them: a few degrees below the heat pump's set point. That way, they stay cold for most of the winter and only switch on if the heat pump needs help. If one baseboard switches on often, a corner of the room is less well served: we can then adjust the direction of the louvres.\u003c\/p\u003e\n\u003ch3\u003eSummer in an open area\u003c\/h3\u003e\n\u003cp\u003eIn \u003cstrong\u003ecooling\u003c\/strong\u003e mode, the nominal capacity is \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e. The \u003cstrong\u003e12.5 EER2\u003c\/strong\u003e rating measures efficiency on a hot day, when the sun comes through the large windows and the kitchen adds its heat; the SEER2 rating of 21.5 sums up efficiency over the whole season. At low speed, the indoor coil condenses moisture from the air, which drains away: continuous \u003cstrong\u003edehumidification\u003c\/strong\u003e keeps the space pleasant without an icy draft.\u003c\/p\u003e\n\u003ch3\u003eThe ratings, one by one\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eSEER2 of 21.5\u003c\/strong\u003e: cooling efficiency over the whole summer.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eEER2 of 12.5\u003c\/strong\u003e: cooling efficiency at the hottest point.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHSPF2 of 11.0\u003c\/strong\u003e: heating efficiency over the whole season, the most important one in Quebec.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCOP of 2.55 at -8 °C, 1.92 at -15 °C and 1.20 at -30 °C\u003c\/strong\u003e: heat delivered per unit of electricity, where an electric baseboard delivers one.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 215324117\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\n\u003ch3\u003eThe $2,160 LogisVert grant\u003c\/h3\u003e\n\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$2,160\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.

We look for a wall, up high, from which the airflow can cross the room lengthwise, rather than a side wall that would leave one end of the space out. We avoid the immediate vicinity of the stove and hood, as well as walls crowded with upper cabinets. The head is secured to the framing with a drainage slope for condensate. The \u003cstrong\u003eload calculation\u003c\/strong\u003e, done during the visit, then confirms that the size suits the whole space.\u003c\/p\u003e\n\u003ch3\u003eOutdoor unit, lines and electrical\u003c\/h3\u003e\n\u003cp\u003eThe outdoor unit goes on a ground or wall stand, \u003cstrong\u003eabove the snow line\u003c\/strong\u003e, away from bedroom windows, including the neighbours', and sheltered from snow sliding off roofs. The \u003cstrong\u003erefrigerant lines\u003c\/strong\u003e, the cable and the drain go through a single sealed opening, and a line cover can finish the run. The system needs a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e: we check the panel capacity during the visit. At \u003cstrong\u003ecommissioning\u003c\/strong\u003e, the circuit is evacuated and checked for tightness, then we test heating, cooling and the drain, and set the baseboards as backup.\u003c\/p\u003e\n\u003ch3\u003eMaintenance and warranty\u003c\/h3\u003e\n\u003cp\u003eRinse the indoor filters every two weeks in season; in an open area with a kitchen, they also catch fine cooking particles. Keep the outdoor unit clear of snow and leaves, and plan annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e of the coils, drain and electrical connections. In winter, white vapour during defrost and a short pause in heating are normal.
