The warm or cool air must also reach the back of the kitchen, the dining area, and the bottom of the staircase. The \u003cstrong\u003eDURASTAR Sirius Heat Wall-Mounted Heat Pump | 18,000 BTU - R454B\u003c\/strong\u003e combines certified heating capacity down to \u003cstrong\u003e-30 °C\u003c\/strong\u003e with a maximum airflow of \u003cstrong\u003e759 CFM\u003c\/strong\u003e, making it a solid choice for large living areas.\u003c\/p\u003e\u003cp\u003eIts certified ratings are \u003cstrong\u003e21.7 SEER2\u003c\/strong\u003e, \u003cstrong\u003e13.0 EER2\u003c\/strong\u003e, and \u003cstrong\u003e10.8 HSPF2\u003c\/strong\u003e. It is \u003cstrong\u003eENERGY STAR\u003c\/strong\u003e certified with the \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e, and Hydro-Québec lists it in the LogisVert program with a \u003cstrong\u003e$1,992 rebate\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eAirflow Range: An Often-Overlooked Criterion\u003c\/h3\u003e\u003cp\u003eA wall-mounted unit blows air from a single point. In a long or L-shaped room, air speed and volume determine whether the heat actually reaches the other end. This system's indoor fan offers four levels: \u003cstrong\u003e371, 441, 500, and 759 CFM\u003c\/strong\u003e. Turbo mode quickly makes up for a temperature difference when you return from work, while the lower levels maintain quiet comfort the rest of the time.\u003c\/p\u003e\u003cp\u003eWall selection is just as important. We position the indoor unit so that the air stream travels across the room's greatest dimension, without obstacles such as a range hood, tall cabinet, or hanging light fixture. The vertical louver oscillates automatically; the lateral direction is set manually during commissioning according to the layout of the space.\u003c\/p\u003e\u003ch3\u003eCertified Heating Capacities\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAt \u003cstrong\u003e8 °C\u003c\/strong\u003e: 18,000 BTU\/h, with a range of 10,300 to 23,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-8 °C\u003c\/strong\u003e: \u003cstrong\u003e16,600 BTU\/h\u003c\/strong\u003e, \u003cstrong\u003eCOP of 2.64\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-15 °C\u003c\/strong\u003e: \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e, \u003cstrong\u003eCOP of 2.00\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-30 °C\u003c\/strong\u003e: up to \u003cstrong\u003e9,600 BTU\/h\u003c\/strong\u003e, COP of 1.43\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe certified value at -15 °C is even higher than the value measured at -8 °C. The key point is this: at -15 °C, the unit still delivers its full rated capacity, producing twice as much heat as a baseboard heater for the same amount of electricity. These figures come from certificate \u003cstrong\u003eAHRI 215359258\u003c\/strong\u003e, published by NEEP, which takes precedence over the manufacturer's commercial specification sheet.\u003c\/p\u003e\u003ch3\u003eThe $1,992 LogisVert Rebate\u003c\/h3\u003e\u003cp\u003eThe system appears on Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e list under \u003cstrong\u003eENERGY STAR ID 3621154\u003c\/strong\u003e, with a \u003cstrong\u003e$1,992 rebate\u003c\/strong\u003e for owners of existing homes. The amount is calculated according to the list in effect on the installation date; we confirm it before signing and prepare the documents required for your application.\u003c\/p\u003e\u003ch2\u003ePlanning the Installation of an 18,000 BTU Unit in a Single-Family Home\u003c\/h2\u003e\u003cp\u003eAt this size, installation affects more elements of the home: the structure supporting the outdoor unit, the electrical panel, and the line-set route. Here is what we check during every visit.\u003c\/p\u003e\u003ch3\u003eAn Outdoor Unit Weighing Nearly 100 Pounds\u003c\/h3\u003e\u003cp\u003eThe condenser measures \u003cstrong\u003e35.04 x 13.46 x 26.50 inches\u003c\/strong\u003e and weighs 99.9 pounds. On a brick or concrete wall, a securely anchored wall bracket is suitable; on vinyl or wood siding, we often prefer a ground stand on a stable base, always above the snow line. Its \u003cstrong\u003e59 dB(A)\u003c\/strong\u003e sound level means it should be placed away from bedroom windows, both yours and your neighbors'. The base-pan heater and the anti-corrosion fin coating are included as standard equipment.\u003c\/p\u003e\u003ch3\u003eLonger Lines, Larger Diameter\u003c\/h3\u003e\u003cp\u003eThis system uses \u003cstrong\u003e1\/4- and 1\/2-inch lines\u003c\/strong\u003e. They are precharged for 25 feet and can reach \u003cstrong\u003e98 feet\u003c\/strong\u003e, with a maximum elevation difference of \u003cstrong\u003e66 feet\u003c\/strong\u003e. This allowance makes it possible, for example, to place the outdoor unit in the backyard while the indoor unit is on the living room's front wall. Each foot beyond the precharged length requires 0.16 ounces of refrigerant. When existing lines of the correct diameter can be reused, their cleaning and testing are included.\u003c\/p\u003e\u003ch3\u003eA Dedicated 20 A Circuit\u003c\/h3\u003e\u003cp\u003ePower supply: \u003cstrong\u003e208-230 V\u003c\/strong\u003e, \u003cstrong\u003e19 A MCA\u003c\/strong\u003e, and a \u003cstrong\u003e20 A circuit breaker\u003c\/strong\u003e. Most 200 A panels accept this circuit without difficulty. In an older home with a 100 A panel already loaded with baseboard heaters and a range, we perform a load calculation before proposing the installation.\u003c\/p\u003e\u003ch3\u003eThe Indoor Unit in Everyday Use\u003c\/h3\u003e\u003cp\u003eThe wall-mounted unit measures \u003cstrong\u003e42.60 x 9.21 x 13.27 inches\u003c\/strong\u003e and weighs 30.4 pounds. Its sound level ranges from \u003cstrong\u003e20 dB(A)\u003c\/strong\u003e in Silence mode to \u003cstrong\u003e55 dB(A)\u003c\/strong\u003e in Turbo mode; during normal operation, it ranges from 25 to 45 dB(A). The remote control provides access to the \u003cstrong\u003eFollow Me\u003c\/strong\u003e, \u003cstrong\u003eSleep\u003c\/strong\u003e, \u003cstrong\u003eGentle\u003c\/strong\u003e, \u003cstrong\u003eActive Clean\u003c\/strong\u003e, and \u003cstrong\u003eECO\/GEAR\u003c\/strong\u003e functions. An 8 °C freeze-protection setting keeps the room above freezing during an extended absence. Wi-Fi is not built in; DuraStar offers a separately sold Wi-Fi adapter module.\u003c\/p\u003e\u003ch3\u003eThe Role of Baseboard Heaters and Existing Heating\u003c\/h3\u003e\u003cp\u003eIn a single-family home, one wall-mounted unit does not heat enclosed bedrooms upstairs. We position it as the primary source for the ground floor, while the existing baseboard heaters take over in isolated rooms and during extreme cold. If the upper floor also needs cooling in summer, we discuss a second unit or a multi-zone solution.\u003c\/p\u003e\u003ch3\u003eUnderstanding Sounds and Pauses\u003c\/h3\u003e\u003cp\u003eA rush of air when the louver moves back into position, plastic creaking after a heating cycle, white vapor during defrosting, and a three-minute delay before restarting are all part of normal operation. An unusual metallic noise, a burning smell, or an indoor water leak requires shutting off the unit and scheduling a service visit.\u003c\/p\u003e\u003ch3\u003eMaintenance\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eClean the \u003cstrong\u003eindoor filters\u003c\/strong\u003e every two weeks during the season.\u003c\/li\u003e\n\u003cli\u003eKeep clear space around the condenser in both winter and summer.\u003c\/li\u003e\n\u003cli\u003eHave annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e performed on the coils, drain, and electrical connections.
