FAQ

Q: How does an Immersion Heater Work?
Immersion heaters are made by encasing a resistance heating wire in a ceramic jacket which is then surrounded by a sheath. The sheath can be made of copper, steel, stainless steel, cast iron, incoloy, titanium, or PFA coated. As electricity flows through the heating element, it moves heat at a high rate through the ceramic jacket and sheath. The heat emanating from the sheath quickly heats the water or liquid surrounding it.
