Wattco’s water heating element

A water heating element is a precise application requiring immersion heaters to heat liquids to specific temperatures in a certain period of time. Wattco screw plug heaters are a popular choice for water heating as they are a perfect product to heat smaller containers (for example up to 500 gallon tanks) to high-temperature ranges within a short period of time. 

Many applications involving smaller tanks use heaters with power ranges of five KW, ten KW and up to twenty KW to heat up their liquids.  For larger tanks (ie. 500 to 500,000 gallons), flange heaters are an excellent choice for their corrosion resistance properties as well as their durability in harsh outdoor environments. These elements have larger power capabilities: from (fifty KW to 100 KW and up to over 500 KW for larger applications.


Maximizing the efficiency of water heating elements

Water heaters use either mechanical thermostats or digital controllers that use thermocouples to get accurate temperatures. Mechanical thermostats are economically feasible for smaller applications and have a maximum amperage rating of twenty-five Amps for single- phase (fifteen Amps for three-phase). RTDs are used for applications in colder conditions where thermocouples cannot relay temperatures accurately. It is always recommended to verify your amperage availability (ie. fifteen Amps, thirty Amps) before selecting an electric immersion heater.


A more sophisticated product is the circulation heater (or inline heater) which uses either a screw plug heater or a flange heater that circulates water in a circuit and reheats it continuously. This efficient process doesn’t require as much energy as a well-insulated circuit would require less energy to heat up the liquid during the second or third pass. Many lubricant oils or oil heaters, use this form of heating to effectively reach the temperature they are looking for.
