Problems started with cold spots - most especially in centre middle of living room rad (3 bed house with 7 rads in total). Was told needed a powerflush to get rid of sludge. Had that done and when guys left the living room rad was no better. Told to leave it a while to see if it 'works its way through'. About 5 days later rad is significantly better across the middle (which was the worst bit) with just a small localised area to the left still cold. Unfortunately there was a 'bang' when heating came on next morning (frightened the cat witless) and subsequently the main bedroom rad was cold at the front (altho hot at the back- its a double convector with fins). Rest of the system now lukewarm. Assumed the blockage had moved and was now upstairs rather than downstairs. Called out the original powerflush gang who now proclaim system is beyond repair and quote £3900 plus vat to replace pipes, rads and boiler. Rang Worcester Bosch as boiler is under maintenance contract. Eng replaced pump and showed me it was full of crud (black sticky gunge) also pcb (more to do with knocking the end off some electrical wire than a consequence of the prob, it seems).Upshot is boiler is now knocking really badly, guage is 'jumping' and there's a water leak (seems to be from the front middle of boiler).
Ideas anyone? Will be ringing WB first thing in the morning but would like to be prepared for any likely squirmy ' not our problem' scenario.
