NEVER buy a BAXI boiler, the assistance is absolutely INCOMPETENT, they are only able to do the annual cleaning asking you for 100 euros.
I have a noise problem and none of these technical to what to do. I also tried to call headquarters to talk with someone competent, NOTHING TO DO remind you from assistance incompetent.
