The Pressure Equipment Directive (PED) and the
Energy Performance of Buildings Directive (EPBD)
require a periodic inspection of heating applianc-
es in order to ensure a high degree of eciency
over a long term and, consequently, the least envi-
ronmental pollution.
It is necessary to replace safety-relevant com-
ponents after they have reached the end of
their useful life. This recommendation applies
only to heating appliances and not to indus-
trial heating processes. DUNGS recommends
replacing such components according to the
following table:
