At -8 °C, the unit provides nearly three times the heat of an electric baseboard heater for the same energy consumption.

Unlike the DuraStar 208-230 V wall-mounted units in our selection, it automatically oscillates vertically and horizontally, controlled by the remote. DuraStar indicates coverage of up to 72 discharge angles, helping air reach the corners of an irregularly shaped room. Its fan offers four speeds of \u003cstrong\u003e200, 235, 270, and 342 CFM\u003c\/strong\u003e, and its sound level ranges from \u003cstrong\u003e28 to 42 dB(A)\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eThe remote provides access to the \u003cstrong\u003eI FEEL\u003c\/strong\u003e function, which measures the temperature where the remote is located, as well as \u003cstrong\u003eECO\u003c\/strong\u003e mode, available in cooling, \u003cstrong\u003eSleep\u003c\/strong\u003e mode, which shuts off after ten hours, \u003cstrong\u003eTurbo\u003c\/strong\u003e and \u003cstrong\u003eMute\u003c\/strong\u003e modes, the timer, and the \u003cstrong\u003eSelf-Clean\u003c\/strong\u003e function. The latter briefly freezes and then defrosts the indoor coil to dislodge dust and deposits responsible for odors, in about thirty minutes; DuraStar suggests using it every three months.

Its compact, lightweight design works well on a balcony or on a wall bracket anchored to the structure. DuraStar's installation manual requires the unit to be placed higher than the average snow accumulation in areas where it snows, with a minimum height of 18 inches. It also recommends keeping the drainage hose as vertical as possible in cold weather so that defrost water does not freeze in the hose. The documentation for this system does not mention a base-pan heater; we therefore pay particular attention to placement and drainage.

For a living room or bedroom that receives a lot of sunlight, the 12,000 BTU model is generally the safer choice.\u003c\/p\u003e\u003ch3\u003eThe heat pump's role in winter\u003c\/h3\u003e\u003cp\u003eIn the fall and spring, with a COP of 3.41 at 8 °C, the heat pump warms the room at low cost. In cold weather, it continues to provide a significant share of the heat while the baseboard heaters, set a few degrees below its setpoint, supplement it as needed. Below -20 °C, it stops heating, as specified by the manufacturer; the baseboard heaters then provide all the heating. This model is therefore not designed to replace a home's heating system, but to reduce its operating cost.\u003c\/p\u003e\u003cp\u003eIf the subsidy or heating in very cold weather is a priority, the 208-230 V models in the DuraStar lineup are better suited. The R-454B Standard 12,000 BTU model, for example, appears on the LogisVert list with a $1,248 incentive and heats down to -25 °C.\u003c\/p\u003e\u003ch2\u003eSuccessfully Installing a 115 V System in a Home: Location, Power Supply, and Maintenance\u003c\/h2\u003e\u003cp\u003eA 115 V unit must be installed with the same care as a 208-230 V model. Here are the points we check.\u003c\/p\u003e\u003ch3\u003eThe indoor unit\u003c\/h3\u003e\u003cp\u003eThe wall-mounted unit measures \u003cstrong\u003e31.93 x 7.95 x 11.50 inches\u003c\/strong\u003e and weighs 19.8 pounds. Its sound level ranges from \u003cstrong\u003e28 dB(A)\u003c\/strong\u003e at the lowest setting to \u003cstrong\u003e45 dB(A)\u003c\/strong\u003e at the Turbo setting, with a maximum airflow of \u003cstrong\u003e342 CFM\u003c\/strong\u003e. The louvers automatically oscillate vertically and horizontally, and DuraStar indicates up to 72 airflow angles. The \u003cstrong\u003eI FEEL\u003c\/strong\u003e function measures the temperature at the remote control, right where you are. It also includes \u003cstrong\u003eECO\u003c\/strong\u003e cooling mode, \u003cstrong\u003eSleep\u003c\/strong\u003e, \u003cstrong\u003eTurbo\u003c\/strong\u003e, \u003cstrong\u003eMute\u003c\/strong\u003e, a timer, the \u003cstrong\u003eSelf-Clean\u003c\/strong\u003e function for the indoor coil, and an 8 °C heating mode that protects the room from freezing during an absence. Wi-Fi is not available on this model.\u003c\/p\u003e\u003ch3\u003eThe outdoor unit on a balcony\u003c\/h3\u003e\u003cp\u003eThe condenser measures \u003cstrong\u003e28.03 x 9.21 x 19.61 inches\u003c\/strong\u003e, weighs 59.5 pounds, and produces \u003cstrong\u003e55 dB(A)\u003c\/strong\u003e. Its shallow depth makes installation on a balcony or on a wall bracket anchored to the structure easier. Where snow is an issue, DuraStar's installation manual requires placing it higher than the average snow accumulation, with a minimum clearance of 18 inches, and keeping the drain hose as vertical as possible in cold weather. The documentation for this system does not mention a base pan heater; drainage of defrost water is therefore a point we pay close attention to. The coils are protected by a Blue Fin anti-corrosion coating. In a condominium, we provide the condominium association with the unit's dimensions, weight, and sound level.\u003c\/p\u003e\u003ch3\u003eThe refrigerant lines\u003c\/h3\u003e\u003cp\u003eThe lines are \u003cstrong\u003e1\/4 and 3\/8 inch\u003c\/strong\u003e, precharged for 25 feet. Their length must be between 10 and \u003cstrong\u003e49 feet\u003c\/strong\u003e, with a maximum height difference of \u003cstrong\u003e33 feet\u003c\/strong\u003e and an additional 0.11 ounce of refrigerant per foot beyond the precharge. The two units must therefore remain relatively close together, which we plan from the outset during the site visit. The installation is entirely exposed, with no need to open an interior wall, and a finished line set cover can be added.\u003c\/p\u003e\u003ch3\u003eElectrical supply\u003c\/h3\u003e\u003cp\u003eThe system operates on \u003cstrong\u003e115 V\u003c\/strong\u003e single-phase power, across a range of 105 to 125 V, with an \u003cstrong\u003eMCA of 17 A\u003c\/strong\u003e and a \u003cstrong\u003erecommended 25 A circuit breaker\u003c\/strong\u003e, according to the manufacturer's product sheet. It must be connected to a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e that complies with the applicable code, without sharing its power supply with other appliances.
