I have a Potterton Puma 80e:
The system works fine save for the fact that when the hot water is running the boiler will switch off and fire back on again periodically of it's own accord. It also does not appear to be able to handle the mixing of cold water to hot through the bath/shower taps as this causes the same thing to happen. - This results in hot/cold showers which is not much fun!
Please could someone advise as to the possible root cause(s)? Thanks
