a quick question regarding heating and water mains

[finest1]

hi all

i've currently had to shut my mains water off as im having issues with plumbing. during this time i have noticed my heating flick on when the thermostat kicks in. i was wondering if shutting the mains off affects the heating system? or can the central heating run as normal. ive turned my heating off just in case of any damage until i hear otherwise

thanks

Your heating only requires "new water" if you drain it, since this is not the case you can leave it on while the water main is off.

thanks, I've switched heating on, seems to be working fine, no strange noises

(Rhetorical question) Why would there be "strange noises?"
