We managed to get a new pump for our 32 year old Worcester Heat Slave boiler last week. The first fitter who looked at the boiler said it was the heat exchanger which was an obsolete part but we weren't convinced, as my husband whose an engineer thought it was the pump.  Second fitter concurred and new pump was ordered and fitted as that turned out to be a general part used on lots of boilers. Dreading the circuit board going though as they are definitely obsolete now.  Might have to bite the bullet at some point and replace the boiler as we realise it won't be particularly efficient compared to the new ones.
