Hi All,

Happy Christmas / Bah Humbug (delete as appropriate).

In the olden times, it was recommended to plumb the towel rail into
the hot water circuit rather than the heating circuit.

What was the thinking behind this?

It would get heated each time the cylinder is reheated - so that is
likely to be after you have drawn off significant amounts of hot water,
like filling a bath.

Some might also configure it as an "always open" path through the system
to create a bypass.

And is it necessary today?

Not often done. Dual fuel rails are probably more common.
