Connecting to tube installation of the central heating system and the start-up of the electric boiler has to be executed
considering all technical standards and norms, on behalf of the authorized person, who is able to take over the
responsibility.
In a closed heating system it is obligatory to build in a certificated safety valve with opening pressure 0,25 MPa (2.5
bar) and the membran expansion vessel. The safety valve and expansion vessel must be build in according the law
regulation and between the valve or expansion vessel and the boiler may not have any stop elements. Boiler is build
for closed heating system (you can not install this boiler in open heating system).
System pump could be connected on the inline (recommendation) or back line.
Depending of the size of the space, which we would like to be heated, its purpose and heat losses, the proper capacity
of the electric boiler has to be chosen.
