Many thanks for the advice regarding fitting the base or wall units first.
However I was a bit ahead of myself there and still have a bit of work to do first. One bit is to replace the radiator. When it was fitted it was a little to long and stuck out slightly into the door frame. Went to B&Q and picked out a radiator, perfect size but it said not to be used on a direct central heating systems. So I lifted this heavy radiator back onto the high shelf and made my way home- not a happy chappy I have a sealed central heating system (No tanks) using Worchester Bosch Highflow 400 boiler. Is this a direct heating system, and if so do I need a particular type of radiator.
Many thanks
