Would appreciate your professional view of this problem with my boiler and chs.
We have recently moved into a 4 yr old house with a gas chs (can supply boiler make if it makes a difference but currently at work). It has micro-bore piping and currently suffers from a lot of noise in the boiler (gurgling etc when lit - esp from the airing cupboard) and general glugging type noises in the radiators. Having had 2 of the rads off the water is inky black (the problem was there before I did so, so I don't think I introduced air.)
We had an engineer out to inspect the system prior to starting a maintenance contract and he has told my wife that the problems are down to sludge and air entering the system as the pipes are (apparently) porous. With them being micro-bore, he said, this is more of an issue than conventional systems. He has recommended a pressure flush through to get rid of the dirt etc and the application of some sort of additive to coat the pipes and prevent build up - a full days work. This will mean the system will then be covered for life. However, at £900, this does seems a little steep. Am I being fed a line here or does this seem an appropriate course of action?
Grateful for any feedback.
