  • 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 87W 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

  • 124 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Exactly what I needed Used to provide extra heat for master bath. Much more attractive option than most wall heaters. Has been going strong for many years.

  • can 2 model 124 heaters be controlled with 1 thermostate?

    Asked by: Mondello
    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.

    Can this unit be mounted in a ceiling?

    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?
    Asked by: MEC
    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.

    heater trips off and have to take grill off to reset why does it trip off

    Asked by: mikie
    Thank you for your question on the model 124 wall heater. If the thermal overload is tripping regularly, the problem is probably one of three things. The thermal overload is defective, there is a build-up of dust and dirt on the blower wheel or the motor has slowed down and needs to be replaced. Please contact the Technical Service Department at 800-637-1453 for further assistance.

    Can you use this model just to push air thru without having the heat on?

    Asked by: Larry
    Thank you for your question on the model 124 wall heater. When the motor is running, the unit will be heating. There is no option for fan only, without heat.
