Screw-in heaters from DEW are the most effective way to heat gaseous and liquid media directly – including in hot water storage tanks and heating boilers. All the important parameters like the installation length, power output and the material are already specified in an extensive product range.
Our CEL screw-in heaters are standard types, which are always in stock at our warehouse to ensure delivery at short notice. Due to our large range, you can either choose between screw-in heaters without control, only with limiter, only with controller or with both controller and limiter.

At DEW, electric screw-in heaters are manufactured with a screw fitting made of stainless steel and a G1½” thread. We use different types of stainless steel as the pipe material for the screw-in heaters. The electrical connections can be fitted with an IP54 protective cap.
Installation information / Temperature control
CEL screw-in heaters can be installed both horizontally and vertically. Make sure that the screw-in heater is always completely covered with medium. If required, we can also supply the heating element with a built-in thermostat with different control ranges. The variants listed below are ready to ship from the warehouse.
