Commissioning (qualified contractors)
5.3.1 Oxygen diffusion
Heating circuit oxygen diffusion
If oxygen gets into the heating system, steel parts may become
corroded, e.g. the indirect coil in the DHW cylinder or the buffer
cylinder. The products of corrosion (e.g. rusty sludge) can settle
in the heating system components. This may cause the pipe
cross-sections to narrow, leading to a lower output.
u Use oxygen diffusion-proof pipes and hoses (e.g. multi-
layer composite pipes).
u If you have an open vented heating system, separate the
heating circuit from the buffer cylinder. For example, you
could use a plate heat exchanger for this.
5.3.2 Fitting the drain valve
u To facilitate maintenance work on the appliance, fit a drain
valve (not included in standard delivery) in the lowest pipe
line.
