all depends on your plumbing skills and access,isolate electricity to boiler,isolate heating tank, drain it remember the boiler could be a low point undo thermistor and change.if access is good bung the tank and vent and do it live :shock: if your quick you will not lose too much water if your...

sigmas are renowned for noisy heat exchangers turn the pump up and the noise will disappear,only cure i can think of is turn the gas pressure down and renew the GOLD coloured thermistor.has the boiler been wired correctly with the pump back to the boiler and a permanent live supply?
