We had a stroke of luck today. I got up at the usual time, and, once dad had put the top half of my clothes on, went downstairs.
"It's a bit nippy," I said. "You're right", he replied. On inspection,the boiler had packed up! Dad rang the people who service the boiler, and they said tomorrow morning was the earliest they could make it. It's due to be -8c tonight, so dad had a look at the boiler. A fuse had gone!!!
We are warm again, and saved the call-out fee!
