Need urgent help - towel rail on single pipe system

[minmax89]

Hi all!
im doing a bathroom refit and the heating is a single pipe system. They've a 3 zone set up - cylinder, downstairs and upstairs. Wireless controls and a new system boiler was fitted about a year ago.

Mall I want to do is add a towel rail in the bathroom But the rad in there has a funky valve on it.

My plumber has told me to essentially connect the two pipes up to continue the flow but tee off twice to the two valves on the towel rail?

can I do this and will it still work if it worked before?

many many thanks for anyone's expert help. Single pipe systems scare the bejeesus out of me!

Assuming you are fitting a trv I would put an auto bypass on the 'link' pipe so that way the towel rail will gain the heat until it reaches temperature, alternatively just fit lockshields.

I had planned on fitting a TRV yes.

Then I read about low resistance TRVs needed. Can't imagine I'll get those too easy in Ireland.

Sorry for my ignorance but do you mean an auto bypass VALVE on the link pipe between the two tee's to the locksheilds/TRV?? As in an auto bypass valve you would use in a sealed system with all rads having TRV's?? The kind you might set to 3 bar or something??

Is it definitely a single pipe system?
Lift a bit of floor under that valve and take a pic

if it is one pipe you defiantly need a one pipe trv cos normal ones are too restrictive.. about £30 each.

Like the plumber said youll have too tee off the loop cos thats all it is..
