I've just fitted a dual-fuel towel rail and understand that I shouldn't switch on the electrical element when the CH is in use.
However, I expect that in Spring & Autumn, when the heating is just ticking over, my rail not be hot long or often enough to dry towels properly, and wondered whether its OK to turn the TVR right down (effectively to off) and leave the electrical element on instead? The lockshield valve will remain open, so the water in the rail can expand/contract.
Can't see a problem with that, but I don't want to damage the element.
