My central heating has broken. It's the pump to be precise, and some valve or other. I've barely thought about the system for eight years when it last went wrong. Of course, had I thought about it and got chemicals put into the system regularly and had the boiler serviced every year etc, it might not have broken down - who knows?. Would have, should have, could have. Let's see if I learn from this expensive lesson in the future.

In the meantime, the house is feeling decidedly chilly and we're rediscovering the charm and comfort of woolly jumpers and pyjamas.
