I have just purchased a Barlo Towel Rail and , in large letters, the installation instructions say that the product is not suitable for direct central heating systems.
What is a direct heating system as opposed to an indirect one? I know the difference in respect to HW tanks.
Is a direct system the same as a closed system as in one heated by a combination boiler?
My system is a conventional one with header tank in the loft etc.
