I have a 1.5 yr old Ariston combination boiler, for about a month now I have had to keep filling the system from the filling loop every day or two before the bolier will dispense hot water. This is annoying when you set it to come on in the morning and it doesn't because the pressure is too low.
Why am I getting this frequent pressure loss? what can I do to stop it?
any tips on this greatly appriciated
