Thanks guys.
The system that I have is a sealed system i.e no tank , so that should not be a problem.
I appreciate that it may cause some problems but am not sure if a mains water flush would be enough for a 9 radiator system in a medium sized semi. What do you think ?
Have had a variety of boiler servicemen look at the boiler over the recent years and a recurring theme seems to be failiure of components due contamination of the system. I can quite believe it as the system was originally installed by a fly by night chancer ( you live and learn ).
Basically...
I have had problems with my boiler for years and now have to bite the bullet and solve the problem - clean out my CH. I have a Potterton Puma 100E and after some examination of the bank balance have come to the conclusion that it has to be a DIY Power Flush !
Any advice , apart from don't or...
