I was at Worcester earlier in the year, you can buy the tools from them cheaper than that.
Some lads use mini pressure washers and even the Worcester trainer said some of their guys use them. Another thing they use is vinegar and bicarb in particular with the ones with baffles.
Got this one. For the kebab heat exchanger this.I did wonder about them, but we don‘t “service” boilers, only safety check, and most of our Worcester stock has been replaced. Is this any good?
Looks goodIf it’s only the blade, what about this?
