I've a Baxi Bermuda back boiler that's coming up to its twentieth birthday. It's now waking me up in the morning with its banging and rattling.
It's a vented, thermo-syphon hot water and pumped heating (if it ain't broke, don't fix it).
Every few years I turn off all the radiators and drain it down at the boiler. I fill the boiler with a de-scaler solution by the drain tap at the boiler using a funnel and hose and fire up the boiler. I leave it a couple of hours, flush out the boiler and re-fill the system, adding a corrosion inhibitor. That normally stops it banging for a couple of years, this time it's only lasted since last Summer.
Any suggestions as to how I can improve the system? I guess it won't be long before I need to replace it, but I'd like to keep it a little longer if I can.
