Electric heating elements

Optimal selection, assembly and use.

EGB and HOT2 electric heating elements are applied as an additional source of heating in central heating radiators out of the heating season. They are especially useful in autumn-winter and winter-spring time when you need extra heating in the room or faster garment drying. The fact that they are electric appliances (home grid ~ 230V, 50Hz) makes them independent from the seasonal central heating systems.

Electric elements used in central heating radiators are electric appliances fitted with heating elements, temperature sensors, electrical and hydraulic connections (connection cord with plug, hydraulic connector) and, depending on the type – control elements (thermal switches and thermostats). All models have male connection threads R1/2”.

An appropriate selection of the electric element to the radiator guarantees proper working of both. In order to simplify the selection the technical data tables for central heating radiators include the information about the optimal power of electric elements to work with particular models of radiators. At the same time, it is confirmation that a particular model of radiator is suitable to work with an electric element. In case of radiators not included in the tables please refer to the rules presented in the following table or in the technical documentation provided with the electric element, making sure that the design of the radiator makes it possible to apply an electric element.

720÷1200 900

NOTE

INFORMATION

“Ladder” type central heating radiators are usually the most suitable ones to work with electric heating elements.

When for the radiator heat output of 480 and 720W the theoretical electric power of the heating element is 300 or 600W and 600 or 900W respectively, it is important to define the final purpose of the set. If the radiator with the electric element is intended to heat an intensively cooled room then in both cases the more powerful element is preferred. If the radiator with the electric element will only be used as a towel warmer, the lower-power element should be applied.
