Installing isolation valves on central heating pipework?

zanwan · 14 Sep 2010

Can i install isolation valves on central heating pipework? I am installing a towel rail after removing an old rad and was wondering if an isolation valve on either side will have any impact on the central heating system?

NOT THOSE! DON'T EVER USE THEM ON HEATING!!

They cost pennies and they behave accordingly. As soon as you touch them after they've been in a short while, they leak.
Use valves approved for CH - very few neat ones around.

99% of those will leak after a short time whe you try to turn them off,and they also restrict flow to some degree.

if you want to use something like that then I would use the real ballofix valves.

There isnt a need 2 isolate the pipework going to a rad, other than the the rad valves, if you realy need 2, use gate valves under the floor they're designed for central heating
