hi, i have had the radiators in my house all changed and new ones put in last week, however after the plumber had put the radiators in, he has not filled the system properly. the boiler is an icont23 combi boiler. it was working fine before the radiators were changed. but now every time i fill the system via the filling loop to 1-1.5bar it empties out to zero in less than 10 minutes. the water i believe is all being emptied out via the overflow outside. could anyone give me any advice on how to rectify this problem please. i would be very grateful as i really cant afford to get a heating engineer out at this moment and time. Thanks.
