I want to tidy up some pipework that runs from the ceiling down through some boxing to a panel radiator, and I want to fit a vertical panel radiator. Can I fit the valves at the top of the radiator and do away with a load of pipework and channelling into a solid wall? I know its a dumb question but if I order the rad an have to have a load of pipework showing, she'll kill me!!!!! Help please !!
