In the middle of summer it’s nice to know that you don’t need to think about heating, right?
Well, you shouldn’t forget it altogether. If you leave your wet central heating system standing idle all the way through the summer, the lubricant around the pump’s bearings will settle, leaving surfaces unlubricated. And if that happens, you’re increasing the chance that the pump will seize when you place it under a heavy load again in the autumn.
So do yourself a favour – once a month, run it for a few minutes (without firing up the boiler, of course!) to ensure that the pump’s bearings stay lubricated through the summer. That way, you can be sure you’ll be able to heat your house when the cooler weather sets in again.
