They are also the rooms where the baseboards run the most in winter and where the heat is felt the most in summer. The \u003cstrong\u003eWall-Mounted Heat Pump CONFORTO MHWAL | 12,000 BTU - R410A\u003c\/strong\u003e takes care of these daytime rooms with a single wall head, in heating as well as \u003cstrong\u003ecooling\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIts certified ratings are \u003cstrong\u003e25.5 SEER2\u003c\/strong\u003e, \u003cstrong\u003e14.0 EER2\u003c\/strong\u003e and \u003cstrong\u003e10.4 HSPF2\u003c\/strong\u003e. The system is \u003cstrong\u003eENERGY STAR\u003c\/strong\u003e certified with the \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e under \u003cstrong\u003eENERGY STAR ID 2495084\u003c\/strong\u003e. It qualifies for a \u003cstrong\u003e$1,200 LogisVert grant\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eThe daytime rooms of a house\u003c\/h3\u003e\n\u003cp\u003eA nominal capacity of \u003cstrong\u003e12,000 BTU\/h\u003c\/strong\u003e typically suits a living room and dining room that open onto each other, or a spacious living room with an office corner. In a multi-storey house, this head covers the ground-floor living areas, while the upstairs bedrooms keep their baseboards or get their own heads later. It is a way to start with the rooms that matter most for the bill and for comfort. If you plan to add heads upstairs later, tell us at the first visit: it can influence the location of the outdoor unit and the line route.\u003c\/p\u003e\n\u003cp\u003eThe calculation still depends on the house. A large picture window, an open staircase that lets heat rise, a kitchen without a partition or older insulation can change the result. We run a load calculation during the visit and tell you whether this size covers the space well or whether another configuration would be better.\u003c\/p\u003e\n\u003ch3\u003eAt -15 °C, the full nominal capacity\u003c\/h3\u003e\n\u003cp\u003eThe certificate lists \u003cstrong\u003e10,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), about 83% of nominal capacity, with a \u003cstrong\u003eCOP of 2.40\u003c\/strong\u003e, and \u003cstrong\u003e12,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), about 100%, with a \u003cstrong\u003eCOP of 1.80\u003c\/strong\u003e. The two points are measured separately; we report each one as published, even though the -15 °C value is higher than the -8 °C value.\u003c\/p\u003e\n\u003cp\u003eWhat these figures say is that the \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e can deliver its full nominal capacity in January cold. For the daytime rooms of a well-insulated house, the heat pump becomes the main heat source; the baseboards, set a few degrees lower, only serve as backup during cold peaks. The ENERGY STAR \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e confirms that the pairing was evaluated for this climate.\u003c\/p\u003e\n\u003ch3\u003eHeat that feels different\u003c\/h3\u003e\n\u003cp\u003eA baseboard heats the air under the window; the warm air rises to the ceiling and comes down slowly. You often end up with a warm ceiling and cold feet. The \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e circulates the air of the whole room at low airflow: heat is spread more evenly, and the compressor adjusts its speed continuously instead of switching on and off. In the evening, when you sit for a long time in front of the TV or at the table, this stability makes a clear difference.\u003c\/p\u003e\n\u003ch3\u003eThe $1,200 LogisVert grant\u003c\/h3\u003e\n\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$1,200\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date. We confirm eligibility before signing and prepare the detailed invoice, model numbers and proof of payment. Our page on the \u003ca href=\"\/en\/pages\/subvention-thermopompes-efficaces-dhydro-quebec\"\u003eefficient heat pump grant\u003c\/a\u003e summarizes the program's conditions.\u003c\/p\u003e\n\u003ch3\u003eSummer on the ground floor\u003c\/h3\u003e\n\u003cp\u003eIn \u003cstrong\u003ecooling\u003c\/strong\u003e mode, the nominal capacity is \u003cstrong\u003e12,000 BTU\/h\u003c\/strong\u003e. The \u003cstrong\u003e14.0 EER2\u003c\/strong\u003e rating measures efficiency on a hot day, when the late-afternoon sun comes through the living-room windows and the kitchen adds its heat at dinnertime. The SEER2 rating, for its part, sums up efficiency over the whole season.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDehumidification\u003c\/strong\u003e is part of summer comfort. At low speed, the indoor coil stays cold long enough to condense moisture from the air, which drains away. The living room stays pleasant at a reasonable set point, with no muggy air and no icy draft.\u003c\/p\u003e\n\u003ch3\u003eInverter and R-410A refrigerant\u003c\/h3\u003e\n\u003cp\u003eThe heat pump moves heat: in winter, it draws it from the outdoor air; in summer, it rejects the house's heat outside. \u003cstrong\u003eInverter\u003c\/strong\u003e technology varies the compressor's speed to follow demand, instead of running all-or-nothing. The circuit uses \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant, in use for many years and well known to refrigeration technicians; service and common parts are easy to obtain.\u003c\/p\u003e\n\u003cp\u003eIn cold, humid weather, frost forms on the outdoor coil. The heat pump then starts a short defrost cycle: heating pauses for a few minutes, a cloud of white vapour may rise from the outdoor unit, then everything resumes normally.\u003c\/p\u003e\n\u003ch3\u003eWhat SEER2, EER2, HSPF2 and COP measure\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eSEER2 of 25.5\u003c\/strong\u003e: cooling efficiency over the whole summer.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eEER2 of 14.0\u003c\/strong\u003e: cooling efficiency at the hottest point.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHSPF2 of 10.4\u003c\/strong\u003e: heating efficiency over the whole season, the one that matters most in Quebec.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCOP of 2.40 at -8 °C and 1.80 at -15 °C\u003c\/strong\u003e: heat delivered per unit of electricity, compared with one for one for an electric baseboard.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210605803\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\n\u003ch2\u003eInstallation, step by step\u003c\/h2\u003e\n\u003ch3\u003eChoosing the wall for the head\u003c\/h3\u003e\n\u003cp\u003eIn a multi-storey house, the head's location is decided with the staircase in mind. Warm air rises: a head placed too close to the stairwell sends part of its heat upstairs. Cold air falls: in summer, the upper floor gets little benefit from ground-floor cooling. So we choose a wall that covers the living and dining rooms, up high, secured to the framing with a drainage slope for condensate.\u003c\/p\u003e\n\u003cp\u003eFurniture matters too. We avoid placing the head above a TV, a fireplace or a heat source that would skew the temperature reading, and we leave enough clearance at the ceiling for air return. The airflow should pass above the sofa and the table, not directly on the people sitting there.\u003c\/p\u003e\n\u003ch3\u003eThe outdoor unit and the line route\u003c\/h3\u003e\n\u003cp\u003eThe outdoor unit goes on a ground or wall stand, \u003cstrong\u003eabove the snow line\u003c\/strong\u003e, often on the side or at the back of the house, away from bedroom windows, including the neighbours'. We avoid spots where snow slides off the roof and passages where defrost water could freeze. 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.\u003c\/p\u003e\n\u003ch3\u003eDedicated circuit and commissioning\u003c\/h3\u003e\n\u003cp\u003eThe 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. We also set the baseboard thermostats with you so they stay as backup.\u003c\/p\u003e\n\u003ch3\u003eMaintenance\u003c\/h3\u003e\n\u003cp\u003eRinse the indoor filters every two weeks in season, 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.
