I’m going to be getting quotes for a new combi boiler install to replace my existing fully pumped system. This will involve scrapping the existing HW cylinder (approx 15 years old) and a Worcester Ri 12kW system boiler (6 years old). Is the boiler worth anything to anyone to be re-used? Or would it be scrapped? Either way, is it common practice to ask to keep the old parts and scrap them yourself, or just let the heating engineer scrap them? I presume the quotes wont make any deductions for the resale of scrap/old parts.
