Hello,
Boiler: Vaillant ecoTEC+ 937.
There seems to be a problem with our boiler.
What seems to happen is that the water gets very hot and people have been scalded.
It does not happen all the time, it happen yesterday evening and today in the evening it has happen a few weeks ago in the morning too.
At first I thought it is the legionaries protection but it happens when the storage tank is switched off.
On observing the boiler the flow temperature stays at a constant 80-85 degrees and it does not cycle.
Can anyone shed any light before I call Vaillant?
