DH heard a horrible noise from the boiler this morning, and when I took a jumper from off the hot water tank, it was quite damp in a couple of places. I called the chap who installed the boiler, and he arrived 15 minutes ago, so far so good. I had taken the shelving out so he could get to the boiler. It is upstairs in our old airing cupboard, and after hoovering up the dust bunnies ? Found a wet/damp patch on the floor. Plumber, looked and said he had never had one of those broken before. Hmmm. He is presently out trying to source a part. Our boiler is covered under a 7 year guarantee, but you can bet that the part, will NOT be under guarantee. Ho hum, we shall see.
