  • 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 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 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 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

    I would like to locate this in a public area and do not want anyone to mess with the thermostat. Is there any way to make this unit tamper proof by modification or using an accessory that you or another company sell?

    Thank you for your question on the model 174 wall heater. Other than totally disconnecting the built-in thermostat and installing a remotely located thermostat, we have no way to make the thermostat on the 174 tamper proof. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.

    Heating element

    My Broan 174 blows cold air. The fan turns on and off by adjusting the thermostat but only cold air comes out. Is this a problem with the heating element or might there be something else wrong?

    Thermostat problems

    Philadelphia, PA, USA
     on 170
    For 10 years this heater did well. Then we had to replace the thermostat twice but we can't get it to work like it used to. The bathroom is cold and the heater runs for a few minutes and turns off. The original thermostat would stay on as long as we wanted and never turned itself off. Either the replacement thermostats are being made poorly or there is another part that needs to be replaced. Please help us to either fix this or tell us if we need to remove the heater and get a whole new one. Is it possible that 2 new thermostats were both defective? Thank you.

    Answers

    Answer: 
    Thank you for your question on the Broan model 170 wall heater. CFM ratings are used for units that ventilate air to the outside of your home. This stands for cubic feet per minute and is the measure of air volume moved by the fan blower. Heater units do not move or exhaust any air, therefore they do not have a cfm rating. If you have further questions, please feel free to contact our Technical Support Department directly at 800-637-1453. They will be happy to help you more.
