What if I do not use my boiler ?

A boiler that is not used at the moment, must be still filled with water. One should not discharge the installation during summer. Instead, in the summer all the doors of the boiler should be open in order to provide draught that will dry the boiler from humidity. Also the steering of your boiler should be switched off so that a lightening cannot do any harm. Even during heating season it should be disconnected when there is tempest outside, as it may cause damage to the steering.
