hi all i have no hot water downstairs it will only get hot if i turn the hot tap on upstairs and then goes cold again when i turn it off i have a worcester 24i boiler. it does not seem to be "asking" for the hot water from the boiler like it does from the upstairs taps i have had this problem before and it was a lot of green/white stuff(hardened water i guess)blocking the pipe which i had to remove and replace a section of pipe? but i dont think it is this this time any ideas
thankyou
andy
