DURASTAR Standard Wall-Mounted Heat Pump | 9000 BTU - R454B

Standard or Sirius Heat: the 9,000 BTU model that prioritizes efficiency over reserve capacity

DuraStar offers two 9,000 BTU wall-mounted heat pumps using R-454B. The Sirius Heat series is designed for extreme cold and provides heating down to -30 °C. The DURASTAR Standard Wall-Mounted Heat Pump | 9,000 BTU - R454B takes a different approach: a heating operating limit of -25 °C, but a better coefficient of performance at -8 °C and -15 °C, a lighter and quieter outdoor unit, and a smaller electrical circuit. For a bedroom, office, or small room already heated by baseboards, it is often the more rational choice.

Its certified ratings are 24.6 SEER2, 14.7 EER2, and 13.0 HSPF2, the best seasonal heating rating among Standard models using R-454B. The system is ENERGY STAR certified with the cold climate designation.

The comparison, backed by certified figures

• At -8 °C: 9,300 BTU/h and a COP of 2.81, compared with 12,000 BTU/h and a COP of 2.46 for the 9,000 BTU Sirius Heat
• At -15 °C: 8,200 BTU/h and a COP of 2.33, compared with 11,500 BTU/h and a COP of 1.80
• At -25 °C: up to 5,000 BTU/h, with a COP of 1.53
• Outdoor unit: 62.2 pounds and 53 dB(A), compared with 72.8 pounds and 56 dB(A)
• Circuit: 12 A MCA, compared with 15 A

In other words, the Sirius Heat retains more heat capacity in reserve as the cold intensifies, while the Standard produces each BTU using less electricity within the temperature range most commonly experienced during Quebec winters. The Standard's figures come from certificate AHRI 215359270, published by NEEP.

When the Standard is the right choice

The Standard is well suited to rooms with little heat loss: a bedroom with only one exterior wall, a well-insulated office, or a dwelling located between two other units. In these cases, the certified capacity is sufficient for most of the season, and the better COP translates directly into savings. Existing baseboards remain in place to take over during extreme cold and below -25 °C, this system's heating operating limit.

The Sirius Heat becomes preferable when the room has two exterior walls, large windows, a floor above an unheated garage, or when you want to minimize baseboard use. We assess this with you during the evaluation, room by room.

Summer: 24.6 SEER2 efficiency

In cooling mode, the certified capacity is 9,000 BTU/h, with a modulation range of 3,100 to 10,900 BTU/h. The variable-speed compressor can therefore run for long periods at low speed, stabilizing the temperature and removing moisture from the air. In heating mode at 8 °C, the range is 4,200 to 14,200 BTU/h, with 10,000 BTU/h certified and a COP of 3.66: autumn and spring days cost very little to heat.

LogisVert and this size

This system does not appear on Hydro-Québec's current LogisVert list, which is why the technical data sheet shows an amount of $0. Its ENERGY STAR ID is 3621165. If the rebate is a factor in your decision, the 12,000 BTU Standard using R-454B appears on the list with a $1,248 incentive; we compare both sizes based on your room and the list in effect on the installation date.

A simple installation for an enclosed room: what we plan for

This size is well suited to quick, minimally invasive installations. The technical details remain the same as for a larger unit.

The indoor unit

The wall-mounted unit measures 31.57 x 7.87 x 11.61 inches and weighs 19.0 pounds. With this system, its sound level ranges from 20 dB(A) in Silence mode to 46 dB(A) in Turbo mode, and its maximum airflow reaches 383 CFM. The vertical louver oscillates automatically; the lateral direction is set manually during commissioning. The remote control offers Follow Me, ECO/GEAR, Sleep, Silence, Turbo, Active Clean, and Gentle functions, as well as 8 °C freeze protection. Wi-Fi is not built in; DuraStar offers a Wi-Fi adapter module sold separately, and the DRSTAT101 wall thermostat is compatible.

The outdoor unit

The condenser measures 30.12 x 11.93 x 21.85 inches, weighs 62.2 pounds, and produces 53 dB(A). Its compact size makes installation on a balcony, wall bracket, or ground stand easier, always above the snow line. The base-pan heater prevents defrost water from freezing, and the fins are protected by an anticorrosion coating.

The lines and refrigerant

The refrigerant lines are 1/4 and 3/8 inch, precharged for 25 feet, with a maximum length of 82 feet and a maximum elevation difference of 49 feet. Beyond the precharge length, 0.16 ounces of refrigerant is added per foot. R-454B is an A2L refrigerant with low global warming potential; the indoor unit therefore includes a factory-installed leak detector. Existing lines of these diameters can sometimes be reused: their cleaning and testing are then included.

Electrical requirements

208-230 V power supply, 12 A MCA, and a 15 A circuit breaker on a dedicated circuit. This is one of the lightest requirements in the DuraStar wall-mounted range, a real advantage in duplexes and condos where panel space is limited.

What is normal

• White vapour outside during defrost, and a pause in indoor heat delivery.
• A three-minute delay before the compressor restarts.
• Heating stopping below -25 °C, confirming the usefulness of keeping the baseboards operational.
• Slight whistling or cracking sounds during temperature changes.

A persistent error code, a tripped circuit breaker, or water leaking indoors requires turning off the unit and calling for service.

Maintenance

Clean the indoor filters every two weeks during the season, keep the condenser clear of snow and leaves, and schedule annual HVAC maintenance for the coils, condensate drainage, and electrical connections.
