Some things need fixing more than once....

A while back I fixed my central heating. And yesterday I did it again. It turns out that having a device that turns on the heating system is good. But having a heating system that actually heats when turned on is even better. The valve that actually lets warm water flow round the house was sticking, resulting in cold toes for Robert. Not a good thing. So now I am a little bit poorer, but a whole lot warmer.
