Upotuslämmitin

Upotuslämmitin, also known as an immersion heater, is a type of electric heater that is submerged directly into a liquid to heat it. This direct contact allows for efficient heat transfer, making them a popular choice for various heating applications. The heating element is typically enclosed in a protective sheath, often made of metal like stainless steel or copper, to prevent corrosion and ensure durability when exposed to the liquid.

Immersion heaters work by passing an electric current through a resistance wire within the heating element. This resistance causes the wire to heat up, and the heat is then transferred to the surrounding liquid through conduction. They are commonly used in water heaters, boilers, industrial processes, and even in some household appliances like kettles and coffee makers. The design and power rating of an immersion heater are chosen based on the volume of liquid to be heated, the desired temperature, and the heating time required. Safety features such as thermostats to prevent overheating and automatic shut-off mechanisms are often incorporated into their design.
