I attach a picture of the Worchester Greenstar 25Si condensing boiler that is no longer required due to the reconfiguration of the central heating system.
It is believed to be approximately 6-7 years old and was so far as I am aware in working order a few weeks ago before we stopped using it. However, you will need to have a Gas Safe engineer do a safety checkbefore installation and no warranty is given. However, as it is still in situ an engineer can check it before it is removed.
Please PM me is you are interested as it would be a shame to dispose of it if it can be put to use. However, any interested party would need to arrange for a Gas Safe registered plumber to remove the boiler and to cap of the supplies.
