My central heating packed up a week or so ago, and after inspection the pipes are choked with sludge and grit.
Ive tried cleaning the pipes out, i managed to get the system working again (including getting one radiator to work that hasnt wored for years) but it still takes a bloody long time to heat up. The pipes are all still very sludgy and i cant get rid of it.
Im planning on replacing the whole lot from the copper pipe after the motorised valve right round back to the copper again with plastic tubing. It is plastic that is on it atm so should be able to route it all easily enough.
Few questions
1: its 22mm and 10mm that is on atm, should i be swapping to 22 and 15mm to help stop the blocking?
2: the only plastic fittings i can find are push-fit, the ones on atm are threaded screw fixing (compression?) i would prefer to use the same type if anyone has any recommendations where to find them?
3: what is the deal with inserts? do they need to be put at all connections? im assuming they just make the ends more flush or something?
Cheers for your help chaps, much appreciated
