  • Powerful register heaters are designed to be wall mounted with a register-look, neutral white grille to make them as inconspicuous as they are efficient. Factory wired at 1500W, at 120V AC, it can be easily converted to 750W at 120v 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
    • Use a line-voltage wall thermostat (Model 86W sold separately) or timer (Models 59V or 59W 60-minute timer or Models 61V or 61W 15-minute timer) for a simple and convenient way to control the heater
    • Rapid warm up time due to an efficient heating element that provides comforting heat in seconds
    • Corrosion-resistant, Nickel-Chrome alloy heating element; manual reset, thermal overload protector; permanently lubricated motor and high efficiency blower wheel combine to deliver efficient operation and durable performance for years of trouble-free heating.
    • Mounts directly to wall studs; housing mask included to prevent construction damage to roughed-in heater. Optional 4-Pack of Rough-in, Housing Only (Model 171H) available for large projects.
    • Wall heaters are intended to provide supplemental heat from a wall location and not to take the place of a 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

    Is it possible to use this unit with just an on off switch instead of a thermostat?

    I looked into your models of timer switches too (which would be ideal) but have read reviews that they make a loud ticking sound. Any suggestions on what my options are?

    Answer: 
    Thank you for your question on the Broan model 120. Yes, you could use a regular on/off switch. Our Technical Support department would prefer to recommend a timer or thermostat switch as opposed to a switch that could stay in the on position. For further questions, please contact Technical directly at 800-637-1453.

    Do you ever answer this questions? The unit will be controlled from a electronic set back thermostat. It is also on with a 4' baseboard heater controlled from the same thermostat. Will that be ok?

    Answer: 
    Thank you for your question on the model 124 register heater. The 124 is to be mounted horizontally in a wall only. It cannot be mounted in a ceiling. If using our thermostat, you could only place one device on a thermostat. We cannot give advice on other manufacturer’s thermostats.

    Answer: 
    Thank you for your question on the model 124 wall heater. We do not recommend controlling two wall heaters with a single thermostat. You need one thermostat for each heater.

    Thank you for your question on the model 128 register heater. The only products that have sound level ratings are exhaust fans. We do not have sound ratings on wall heaters.
