Hi all,some months ago came on here asking advice for my "old" potterton 50 boiler,that had a fault.Following advice on here had the part replaced and again is working fine.Today warmfront engineer called to do technical survey to install(disabled wife).I had thought about this beforehand and having read threads previous on here about being crap,sent him away,he seemed quite suprised,but its a grant for nought he said, aye i replied and crap they are too.Hope my old "Potty" lasts a few more years now,or will have the wife chewing my earholes.
