A member recently asked on FB , how to access the boiler buried under the bed.
In the true spirit of the “Deffy” spirit we had the following respones :
I have a similar arrangement with the boiler being boxed in and under the bed. I recently replaced the 2 240v heating elements and it took me quite a few hours first removing the bed frame and the boxing to be able to access the boiler.
However, you may find there is an easily removable panel on the end of the boiler. This is the end where the pipes and gas line enter. If you can remove that panel, you should find a couple of plastic panels on the boiler casing which when removed give access to 2 fans. These get clogged up with dust, so this might be your problem.
Good luck.
