A business in DuPage County, Illinois, requested the installation of electric heaters for one of their buildings. Several 15kW electric heater rentals, which are certified by UL and CSA for their safety, were installed throughout the facility and connected to the electrical panel in the basement. Portable heaters are available in 115, 208, 240, or 480 - volt power. In the absence of heat, any temporary heating solution for freeze protection is welcomed to avoid the alternative of ruptured water pipes
