Description

The screw-in immersion heater is used for heating up domestic and heating water like e.g. as an emergency heater in case of failure of the heat generator, as an additional heating system for air / water heat pumps and solar systems.
Due to its small design, it is ideal for a space-saving installations.
The immersion body is supplied with temperature controller, safety limit thermostat and operation pilot light.The heating body is made up of 3 U-shaped tubular heaters soldered into a pressed brass nipple. The non-heated zone is 150 mm for all capacities.If the switch-off temperature of 110°C is exceeded, the switching device turns off and remains locked in this position. Reset is performed manually and is only possible after the filling pipe has cooled off by approx. 10 K. The unit can be fitted horizontally or vertically. As soon as the screw-in immersion heater is to be put into operation, the heating elements must be entirely covered by liquid and the circulation of the liquid must not be obstructed.
