This is a pretty cool project. Most of us are used to temperature controlled ceramic heating elements, but there are other ways to get those irons up to temperature. Using scraps from older ...

Resistive heating elements are either composed of metallic alloys, ceramic materials, or ceramic metals. Joule heating, also referred to as resistive heating, or ohmic heating, is a phenomenon where ...

HIGH HEAT EFFICIENCY: Adopts of PTC ceramic heating element and aluminum tube, low thermal resistance, high heat transfer efficiency. CONSTANT TEMPERATURE: The PTC air heater is a electric heater ...

The ceramic heating element ensures efficient and consistent heat distribution. The heater comes with overheat protection, a tip-over switch, a compact design, and a built-in carry handle.

Instead, a circular heating element similar to those used in 1950s electric cooker hobs is placed beneath a swathe of ceramic glass. Turn it to full blast and you can easily see its glowing red ...
