I just painted my new apartment with some orange, more orange, and lavender paint. Here’s a great way you can make a IR PaintRemover! (good find, Phillip!)
The new unit would be a departure from the old. This new unit would be based on a ceramic emitter rather than your grandfather’s quartz tubes of yesteryear. Why ceramic? One reason is that a ceramic unit would be easier to build with fewer parts. Commercial ceramic emitters are readily available. Efficiencies for ceramic emitters run from 85 to 96% whereas quartz ran around 60%. Therefore, a higher percentage of the energy supplied to the unit would be transmitted as infrared rather than light. Quartz rods tend to have infrared hotspots. Cermaic on the other hand, produces a more evenly distributed heat.
