I wonder if you can help me. I have a Pott Puma 100 about 3 years old. In the last few days the hot water temperature has dropped so that it is just warm. If I reduce the flow quite a bit the water comes out a bit hotter but I can still keep my hand under it, before I couldn't. The hw temp on the boiler is set to max. The CH works fine and the boiler is firing up as expected.
Any ideas what it could be? I'd be very grateful for any feedback.
The pressure gauge black line is at 1.5 and the red is at 3.5
Keep up the great work.
