Here's a pic of the offending kit - just where you'd put a double bed

We've had a Simé combi for about 14 years. Things like fans have been replaced but content so far.

Freeing this room is a great investment, certainly adding value to the property as well as decent use. Hopefully you've got a convenient outside wall which will core-cut without too much difficulty when you hang the boiler on it.

Boilers in bedrooms are not ideal - the muffled explosion as the main burner ignites every time someone turns on the hot tap could be quite irritating for a light, or indeed most sleepers. Unless it were in a cupboard??
