Towel Rail Plumbed from above

[NBS]

Hi i am renovating a bungalow we have installed a new central heating system. long and short of the story in the shower area my plumbers installed a chrome flat towel rail, which we piped from above so basically the towel rail is upside down.
We did this as walls are paramount egg box and didn't want pipes coming through cappuccino marble

No air in system (manual Bleed in loft) but the towel rail only gets hot 2/3rd from top down any ideas? my plumber says has installed this way before no probs. We got hot when commissioning by basically bleeding water from bleed vale until hot then topping up system.

If it's bottom entry you could use a dip tube on the flow.

Hi thanks for reply

Am i right in thinking Solder a length of 15mm copper onto the insert of the return pipe or something similar?

or 10mm if 15 won't fit

Worked a treat with 15mm! One very hot towel rail

Many thanks for help!
