Plastic Vent Pipes for High Efficiency Condensing Furnaces

Plastic Vent Pipes for High Efficiency Condensing Furnaces

High efficiency condensing furnaces have two stage combustion to extract as much heat energy as possible from burning gas. After the first stage, the hot exhaust gasses are cycled through a second combustion stage, resulting in exhaust with very little heat. This process creates condensate, or moisture, from the furnace's heat exchanger.

Light emitting diode

Light emitting diode

A light emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor.
