I've got a towel rail in my bathroom that is heated from my combi boiler. I'd like to fit a TRV to the towel rail. Is there any reason why I shouldn't do that? Should I buy a specific type of TRV, or would any TRV do the job?

Some engineers - in the uk - do not recommend fitting a TRV to the bathroom rad as a constant flow is required around the CH system for safety reasons. This is what I was told by a Gas Safe Engineer. The bathroom is a Wet Area so why do you need a TRV when all you want to do is keep it / get it dry. Unless others say so then no need to fit one. Two normal flow valves will suffice on a balanced system.
