3.7 Boiler connections / storage tanks
The boiler must be connected to an energy store through a recycling system having the
following function (this stipulation is obligatory in order to keep the guarantee):
-
The circulation between the boiler and the heating implements (the energy store, the
storage tank, the heating installation...) must be absent as long as the boiler has not
reached the temperature of 60°C.
- When the circulation between the boiler and the heating implements is made, a
permanently controlled reheating to minimum 60°C is obligatory and is done by a by-pass
between the boiler flow and the return to the boiler (recycling).
Hydraulic connections to the boiler: preserve an easier access to care / maintenance
