Sludge removers Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

If you've drained the central heating system, then add a sludge remover into the header tank as you're refilling the system, won't some of it get into the hot water system and come out of the hot taps?

No, you need to add it to the F&E tank for the central heating. Not the header tank - this supplies water to the cylinder for hot water.

Describe your system, boiler, and tanks .......
