  • This wall heater is perfect for bathrooms, entryways, or other small areas where you need added warmth on demand. Factory wired at 1,500W, at 120V AC, it can be easily converted to 750W at 120v AC or 1,500W at 240V AC for added versatility.

    • White grille has downflow louvers to direct heat gently toward the floor and a one-piece design with baked enamel finish for durability
    • Adjustable, front-mounted thermostat offers a simple way to control the level of heat
    • Rapid warm up time due to an efficient Alloy heating element that provides comforting heat in seconds
    • Heater may be recessed or surface-mounted, depending on your application (surface mounting requires Model 84 surface mount kit)
    • Permanently lubricated motor, high efficiency blower wheel, Nickel-chrome alloy heating element and a manual reset thermal overload protector combine to ensure reliable operation and years of trouble free heating. UL Listed for safety.
    • Also available in project packs (171H Rough-In Housing Kit, and 174F without thermostat or 174FT with thermostat Finish Kits) for the convenience of contractors working on multi-unit projects
    • Wall heaters are intended to provide supplemental heat from a wall location and not to take the place of the home’s main heat source
  • How To Size a Room – Quick Calculation

      Moderate Climate (with 8’ ceiling and adequate insulation)
    • Square Footage x 10 = Watts required
    • Example: 100 Sq. Ft. x 10 = 1,000 Watts

    • Colder Climate (with 8’ ceiling and adequate insulation)
    • Square Footage x 15 = Watts required
    • Example: 100 Sq. Ft. x 15 = 1,500 Watts

    How To Figure BTU’s

    • Wattage x 3.413 (constant) = BTU’s (British Thermal Unit)
    • Example: 1,000 Watts x 3.413 = 3,413 BTU’s
    • Example: 4,000 Watts x 3.413 = 13,652 BTU’s
    • One BTU is the quantity of heat needed to raise one pound of water one degree Fahrenheit

    How To Figure Amperage

    • Watts/Voltage = Amperage
    • Example: 1,000 Watts / 120 Volts = 8.33 Amps

    How To Figure Voltage

    • Watts/Amperage = Voltage
    • Example: 1,000 Watts / 8.33 Amps = 120 Volts

    How To Figure Wattage

    • Voltage x Amperage = Watts
    • Example: 120 Volts x 8.33 Amps = 1,000 Watts
    • Example: 240 Volts x 4.16 Amps = 1,000 Watts

    Rated 5 out of 5 by Great product This product fulfills my expectations. It heats well, looks great on the wall and has helped warm our often cold bathroom. I would certainly recommend it. I had it installed on the wall, instead of recessed, and it does not protrude out that much. I am very satisfied. February 3, 2014
    Rated 5 out of 5 by This wall heater does my 10'x12' bathroom perfectly. Love it. My wall heater got hit by lightning, (12 yrs. old) bought new one,same model and replaced old mtr. and grill in less than 20 min., left original housing in wall. Everything interchanged perfectly. No crazy design changes. Good job Braun August 21, 2013
    Rated 4 out of 5 by Great features, easy to install. Installed, had bad thermostat. Called company, they sent a part to fix within 3 days. Good product. August 21, 2013
    Rated 5 out of 5 by excellent little heater I installed this exact same heater when it was called Nautilis 20 years ago. It still works but is looking a bit worse for age. I am replacing it with this Broan model as it appears just as well made, hope it lasts just as long. February 24, 2013
    Rated 5 out of 5 by Wall Heater Built-In Thermostat, 1500W Heater is excellent. Very quiet. Much quieter than the previous heater it replaced. Love the color white. The old one was an ugly stainless steel. Would recommend to anyone. Easy to install. March 28, 2013
    Rated 5 out of 5 by Another Great Purchase I reviewed the broan 192 and 194 and purchased both broans for a second time. Each product worked perfect for the area and size of the apartment. I will purchase the product again for the next remodel, since each apartment is the same size. My contractor and I reviewed the stats and details and decided on these products. NO problems. March 29, 2012
    Rated 5 out of 5 by Second purchase Purchased twice. Great heater for small room. Looks great in wall. This one replaced the same heater we had before we remodeled. We moved the other to a game room. September 2, 2011
    Rated 5 out of 5 by Broan Wall heater Works great. Is safe to use in a smaller space. November 16, 2010

    Thank you for your question on the model 170 wall heater. There should be no problem using a 15 minute line switchable timer with this unit and locating it two feet above the 170.
