We are foreigners with a B&B in Northern Italy. A few days ago the combi boiler stopped working. Circuit board broken. Our guests without hot water! With the expert help of Ricambi Caldaia Fast, we found the right circuit board and ordered it from Ricambi Caldaia Fast. They sent the package with express courier and we received the package within 24 hours. Combi boiler functions fine again. Thank you Ricambi Caldaia Fast! Five stars for you!
