Oh right. So why to they give BTU output and why do plumbers measure the area of the room before recommending the size and output of the required towel rail. I think you'll find that towel rails are used as and designed for heating rooms as well as heating towels. All our towel rails are plumbed to the CH circuit too.Heated towel rails are designed to warm towels, not to heat a space. They are usually taken off the primary circuit (higher temperture to heat hot plumbing water in cylinder), this also means they will be on when you want to heat hot water only.They are a personal choice.
