Friend has 2 bed semi with conservatory , conservatory rad wont get hot unless you shut down other rads ? tried balancing no joy .
system is combi with normal good pressure which should eat this system.
the pipes to rad go into floor under external wall and then up to rad , but cant be blocked as it gets hot if other rads shut off .
any ideas please as i cant think of anything else . howy

Wont Eat the system, if the load on the pipe work is not correct!!! Is the pipework 10mm

You aren't balancing it properly. Water is lazy and heads back to the boiler at the first opportunity.

Hi
pipework is 15 and 22 mm
wether or not i balanced it correctly is debatable , i would have said it is as good as it gets , but worth revisiting
cheers ... any more ideas ???

Have a look at the sticky about balancing.
