    • Pro Installation

This listing is not for a complete heater. Sterling part number 43468000 is required to complete this heater assembly. 

The power of radiant heat, the Sterling infrared tube heater puts the warmth of the sun inside your building, and it reduces your fuel bills up to 50%! Its radiant heat warms people, concrete floors, and objects. The heat is absorbed and re-radiated to warm the entire area through convection. This, combined with the fact that it is powered by gas, adds up to one unbeatable combination. So, consider a very warm and efficient alternative to competitive heaters just blowing hot air. Consider the Sterling infrared tube heater.

General Features

  • Solid State Ignition System - Reliable electronic direct spark ignition system with 100% gas safety shut-off control and 30-second prepurge. . . safety and efficiency assurance.
  • U-Tube Design - Provides uniform emitter tube temperatures and energy distribution on the floor. . . unlike straight tube heaters which are always hotter at the burner end than at the exhaust end.
  • Warranty - 5-year limited combustion chamber warranty.
  • Other Features - Heavy-duty combustion chamber, aluminum reflectors with 97% reflectivity rating, diaphragm safety switch for proof of venting, and system indicator lights.
