our boiler 20 yrs old but was working fine, no noise everything very hot. 3/4 out of 5 downstairs rads not heating up 2 just warm the other cold. Got someone in to flush with acid spent whole day doing it said there were no blocks now but since he has left not one rad in the whole house will heat. He fitted new pump and it now sounds like we are living inside a washing machine whith all the pushing of air and the boiler also founds very funny now. Any ideas on what this could be? we will obvoiusly be getting him back to sort but this happened of Friday and his phones are all off fot the weekend. Also they charged £500 +VAT including new pump, does this sound alot for the South East?
Thanks
