Anyone had experience of changing the DHW heat exchanger on the aforementioned ? Note this one is not the normal 'screw in' type - its the rarer model that is secured with bolts/nuts on the heating and water inlets.
Only manuals I have are for the more common models that have the two securing screws that are easy to change !
Any advise would be welcome before I tackle the job !
