Radiator Removal for Sludge Cleaning From Ariston STI 210 Indirect System Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

[cinn]

I want to remove a radiator that is sludged and clean it out. I know how to do this without draining down the system. However, I have an Ariston STI 210 indirect cylinder and am not sure whether, having emptied this radiator I need to top up system myself or whether it does it on its own. If I need to do it the instruction booklet does not specify how.

Any ideas?

Hi cinn

This will not affect the cylinder, but you will still need to top up the system.
