When to flush a central heating system?
Posted: Wed Jan 09, 2008 9:30 pm
Our central heating system is 6 years old and apart from a recent problem with an intermitant vibration in the hot water pipe (see earlier question - any help would be appreciated) works fine. My question is should the central heating system be cleansed, drained and refilled after a certain period. When I last bled the rads a little the water seemed pretty clear.
Thanks
