My mother has a Ferroli Modena80 combi boiler in her two bed flat.
She has just told me that after she has turned on the hot water supply the radiators turn off as usual but when she turns the Hot Water off the radiators can take up to 20mins to warm up again.
She called out a plumber who took a look and wasn't too sure what the problem could be but suggested flushing the system out. The system was flushed out last year.
So, can anyone help as to what the fault could be ( if there is one)? My mother insists that the CH never took as long to heat up earlier this year.
many thanks in advance
