1ST Series Electric Heaters

NOTE: This type of heater is NOT something you plug into a regular wall outlet. They use a lot more current (amps) than a wall outlet provides. An electrician is typically required to connect the heater to a breaker box.

temporary electric heater The 1ST Series Electric Heater is a complete line of indoor electric heaters with a capacity starting at 34,130 BTU/h. The units are completely self-contained and can be left unattended with no need for re-fueling or venting of combustion gases. Safe for small enclosed areas. 1ST Series electric heaters provide a temperature rise in two hours. Safety features include screens at each end of the heat drum and a thermostat for temperature control. The units have bright colors for high visibility.

Great applications for the electric heater line include:

  • Retail Stores
  • Construction Sites
  • Temporary Office or Warehouse Heat
  • Facility Maintenance
  • Interior Finish Work
  • Flooring

Eliminate Hassles!

emergency heater The electric indoor heater eliminates the hassles of fuel-fired heaters. It requires no fuel. Produces no flames. Needs no late night monitoring, and does not require regular maintenance. If your indoor temperature is 10F....you could use a 15KW, 208V, 3-phase model to heat up to 12,800 "CUBIC" feet (35' X 35' X 10') of insulated new construction. Normally, this would produce a 60F temperature rise in about 2 hours. Once the desired temperature is reached, the thermostat will cycle the heater on and off to hold the desired comfort level. To achieve this, the 800 CFM fan recirculates and warms the air more and more each time it's drawn through the heater. For best results, use in an enclosed air space with a ceiling height of less than 15 feet.
