ELECTRIC HEATING ELEMENTS
Optimal selection, assembly and use.
DESIGNED PURPOSE
Instal-Projekt electric heating elements are applied as an additional source of heating in central heating radiators out of the heating
season 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.
INFORMATION
Electric heating elements can work with various types of bathroom and design radiators.
DESIGN
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”.
SELECTION
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.

NOTE
When for the radiator heat output the theoretical electric power of the heating element is in the lower
or upper range, 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 dryer, the lower-power
element should be applied.
