Having removed burner and electrode from Keston 170, was amazed by the amount of calcium build up inside the heat excanger, the top coil was completely encrusted with the stuff and a large build up in the base of the centre chamber. Is this normal or indicative of condensate drain problems or incorrect burner setings ( the burner looks fine) Heat exchanger only about 4 years old.

Get yourself a Hyrdoflow....
Thats' why the boiler should be serviced every year, except the Kestons heat exchanger can't be cleaned properly due to it's design.
I guess you are not registered...how are you going to check the gas/air connections, gasket sealing and carry out flue gas analysis?
These boilers are junk and suffer from many problems.

Just read up on what a hydroflow is but can't see how that would help as the buildup is due to the water in the combustion gases. Anyway spent the afternoon gently descaling the large lumps, there must be some type of solution that can be used to break down the remaining deposits. Any suggestions ? A mate of mine is actually on the job, he is CORGI, but his first encounter with a Keston. I'd rather get the HE really cleaned up before he comes back to bolt it up and test it with his box of tricks.

A canister of compressed air and a hoover will clean alot of it out and a kettle of boiling water would be good to pour down the flue afterwards.
Kestons are very poor boilers though, if you can afford to it would be wise to save up for a replacement.

its indicative of a pile of junk boiler, that was designed by a muppet
I think I get the message, KESTONS are RUBBISH, but unfortunately in the current economic climate a replacement is not an option, I'll have to nurse this one for a couple of years. Saying that the ridiculous cost of their spares (£7 for a burner gasket) will make any major repair prohibitive.
