Extension Radiator Problem

[peteward15]

Guys & Gals

Having a nightmare with this. Please help. Built an extension and have run a flow and return for a new Rad in the new extenstion. Everything went to plan except the new rad doesn't get hot.

The system seems in tact and there is water in the new rad (bled it and water comes from the valve) and from the return there is water also coming from the return.

I thought maybe an airlock so I turned off all the rads and put the pump up a notch but still nothing.

What else can I do?!??!?!

Help Please

Pete

Try to describe exactly where you connected your new rad to

It was down stairs and was the end of the run as far as rads were concerned!

Take rad off and in turn open rad valves and let water run out into bucket until water runs clear or air bubbles stop etc. a good few minutes. Put on again and try once more.

When you tried this before was the water getting hot out of valves?

Are you sure it's a 2 pipe system?

++++++++++++++++++++++++++++++++

What type of system is it? open vent ,combi etc?

 

[peteward15]

Yep it's a two pipe system alright, of the open vent variety!
