Hi folks,

Just had a whole load of stuff done in my flat including installing CH
and rads. This was all sorted, but one rad had to be removed
temporarily to replaster a wall. It's all now back on and I've
managed to represurise the system (no thanks to the boiler
instructions) and bleed the rad. So my question - do I need to add
more system inhibitor? I hoping not since I'm pretty clueless with
plumbing!

System is a Worcester 25Si combi in a flat with 5 radiators and a
towel radiator if that makes a difference.

Thanks,

Ed

Are you sure that there was inhibitor in there before? If there
was, then if you only lost the content of one radiator and no more then
no more inhibitor should be needed. If in doubt, you can always
add some - it won't do harm. Fernox do a gel product which can be
injected into a radiator which works well with sealed systems.
