hey folks anyone had any experience of this in their homes, last night after a weekend away turned the heating on to get the chill off the house and the radiators took quite a bit of time to get up to temp with cold spots in the middle bottom of pretty much all of them. called round today for a quote to do the job was shocked with how much it was between 600-750 ex vat which seemed high until I realised I have like 13 radiators in the house and the bloke would be here pretty much all day flushing and installing a magnaclean.
