  • Product Overview

    Warm large areas quickly and quietly with the QMark BRH Portable Contractor Heater. Available in two heating capacities from 3,000 watts to 5,600 watts, these portable, industrial strength heaters are ideal for construction job sites, commercial workshops, and any other large unheated area that may need a boost of warmth. With sturdy steel intake and discharge grilles, a built-in thermostat, and thermal protection, the QMark BRH portable heater delivers safe, effective heat wherever you need it most.

    Industrial-Strength Performance

    Working on a chilly, drafty construction site can impede performance. Stay warm and productive on your job site with these QMark industrial heaters. Available in the following heating capacities, QMark BRH Contractor Heaters were designed to meet your comfort needs.

    BRH402 4000/3000 16.7/14.1 240/208 13,650/10,238
    BRH562 5600/4200 23.3/20.2 240/208 19,110/14,333

    All of the QMark BRH models include a steel spiral fin brazed to the metal sheathed element and a permanently lubricated motor for maximum heat transfer. These heaters also feature a red powder-coated epoxy finish to protect the heater from corrosion. For proper operation, these heaters require a 240-volt 30 Amp NEMA #6-30R receptacle.

    Convenient Adjustable Thermostat

    For added performance and comfort, these construction heaters include a built-in thermostat. The adjustable thermostat allows you to set the heater to your desired temperature, and the QMark BRH heater will automatically maintain it. To take advantage of this feature, choose either the low- or high-heat setting and turn the thermostat dial to the full clockwise position. Once the room reaches your desired temperature, slowly turn the dial counterclockwise until you hear a click sound. The heater will now maintain this temperature by cycling on and off automatically.

    You can also take advantage of the QMark BRH562’s fan switch. If you set the rocker switch to the On position, the fan will run continuously and the elements will continue to cycle with the thermostat setting. When placed in the Auto position, the fan will cycle automatically with the thermostat setting. To use the fan without heat, turn the thermostat dial to the full counterclockwise position, and the fan will provide a cool breeze. This setting is perfect for circulating air throughout your work space on warm days.

    Secure, Rugged, and Portable Design

    The QMark BRH industrial heaters come with great safety features to protect you from accidents at home or at a job site. Each heater is equipped with thermal protection, which will automatically turn the heater off if excessive temperatures are reached. The intake and discharge grilles are steel constructed and finger proof to prevent accidental contact with the heater’s internal elements.

    Weighing just 19 pounds, each heater stands 14 inches tall, 10.5 inches wide, and 11 inches in diameter, so you can easily transport them between work sites, the office, or even home. QMark BRH construction heaters also come with a convenient carrying handle that can also be used for storing the heater’s six-foot industrial-strength power cord.

    QMark construction heaters are UL listed products, which means that they have met all of the standards required by this safety testing board. Each heater also comes with a generous 5-year-limited warranty on the element and the motor.
