Consistant Quality

  • Each BTU heater is inspected by a qualified technician for correct size, KW rating, element design, wiring, components and spacing.
  • Every BTU heater is dielectrically tested and recorded
  • Each heater is assigned a work order number to insure that, if the need arises, BTU can quickly locate the wiring diagram, the components used, and the ohms & gauge of elements installed.
  • An “exact” wiring diagram of each heater is attached to its cover and illustrates how the heater is wired, where the components are located and is color coded for easy tracing.
  • BTU duct heaters are listed under UL File #E50663 and ARL File #29706. Product line heaters are listed under ARL File #29707 & 28916
