Immersion heaters are submerged directly into the solution being heated, so there’s no loss of heat during energy transfer. These types of heaters are most suitable for water-based, nonflammable solutions in metal, glass, or other high-temperature containers.
The small heaters can be used to warm coffee or tea. More robust immersion heaters used in labs and industry are also called immersion water heaters or tank heaters. They are submerged directly into a heated solution, so there’s no loss of heat during energy transfer and are easy-to-use, efficient, and operate best in water-based, nonflammable solutions in metal, glass, or other high-temperature containers.
Many offer heating elements made with 316 stainless steel or PTFE-coating, which can be used with chemically aggressive solutions. Both types are available in multiple shapes, sizes, and wattages.
For heaters without built-in temperature controllers, you may need a separate variable-voltage or variable-time controller.
