Have a pumped system, which generally seems to be working fine.
However, during the night we get several bangs, which seem to come from the system somewhere (but not the boiler area). Sometimes these are very loud. Each time the noise can be best described as a \\\'thump-thump\\\'. Often wakes us up.
These can occur several hours after the system has been switched off. It\\\'s very strange and is really doing our head in, any suggestions people might have would be appreciated more than you know.
(Interestingly - or not - it seem that my father-in-law has a similar problem).
