DD's bedroom is noticeably colder than the rest of the flat, so I think the radiator there is inadequate. Is it straightforward to replace/enlarge the radiator in her room, and if so, how would I go about having this done? Any guesses on cost involved? Or would it be easier/cheaper to simply get a supplemental heater that plugs into the wall socket?
It's particularly an issue on these cold nights, and I've taken to leaving the heating on all night so it doesn't get too chilly in her room. Any thoughts/suggestions?
