Hi folks,
We have just moved in to a one bedroom cottage with a Viessmann Vitodens 100 condenser boiler with a Grundfos 3 speed heating pump which at present is on the middle speed setting,the pump is quite noisy and I'm wondering if it's safe to turn it down to the slower speed and will that effect the boiler at all.
W also have a water pressure problem and I've noticed that the boiler occasionally puts up fault code 0b does that indicate anything serious ?
Thanks.
