Below is a list of Duct Heaters manufacturers from Houston, Texas.

A duct heater is a heavy duty modular unit installed in the ventilating ductwork of commercial, residential and institutional HVAC systems, although smaller "duct" heating elements are used in the forced air heating systems of vehicles. Duct heaters can be complementary to a central heating system that utilizes forced air heating, also known as forced circulation heating or convection heating, where air is the medium that transfers heat. Fans and blowers are integral to the transfer of heat; their motion conveys the air through the duct heater.
