After about a month of my new boiler being installed there was no hot water and the day later there was no heating. The company that installed it sent out someone that night to see if it could be fixed. The weather was very cold and they didn't want me to be without heating and hot water. The engineer couldn't fix it. They contacted Veissman who said no-one could come to me till after the weekend, leaving me a week without heating or hot water. The engineer came from Glasgow just to fix my boiler, instead of someone a few miles away from Aberdeen, which he wasn't very happy with, and I didn't think was efficient. He did a good job and diagnosed that the fan had died. Does this mean it was an old fan? I was happy to pay what I did for the boiler but not one that is faulty! Hopefully the boiler will continue to work especially as it is the middle of winter and I have been well and really don't want to be in the situation of having no heating and hot water again anytime soon! The boiler has been working fine since the replacement, thank you.
