    • 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 170F without thermostat or 170FT 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

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

    Rated 5 out of 5 by from 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.

    How loud is it?

    Is there a sound rating in sones?
    Asked by: Anonymous
    Not to my knowledge on this model as it probably wouldn't register on the meter. I find it very quiet.

    Will the Broan 174 thermostat circulate off and on to maintain a temperature setting

    Asked by: Anonymous
    Thank you for your question on the model 174 wall mounted fan forced heater. The 174 has a thermostat on the front of the grille that can be set and will cycle the heater on and off to help maintain a particular temperature in the room. Please remember that our heaters are made for supplemental heat only and not for the primary heat source in the room. If you need further assistance please contact our Technical Service Department at 800-637-1453.

    Can Model 174 be installed in existing construction with steel studs?

    I have 16" on center steel studs in existing construction. Your installation instructions show new construction with wood studs. Is it possible to install in my situation without using kit 84 to mount on the wall instead of within the wall?
    Asked by: Anonymous
    you could but the housing would show if it is surface mounted and you would have to drill a entrance hole for #12 wire to come thru the back side of housing. I cut a hole in my drywall the size of the housing next to the stud and slid it in then screwed to the stud.

    Where is reset button - manual reset?

    Asked by: Marilou
    Thank you for your question on the model 170 wall heater. After you turn off the power to the unit and remove the knob and grille assembly, you will see the button marked reset.
