So every so often I hear a gurgle from the kitchen, and air gets into the rad. Every few days, I bleed it to let the air out. It’s what I think you call a vented system? Little header tank in the attic.
Anyway, I’m assuming that, if air gets in, by the laws of physics water is getting out. Somewhere. The pipework is under the concrete floors… I assume there’s a leak down there somewhere, but I’m not planning to dig all my floors up to find out… am I right to think this, or are there any other possibilities? There isn't any water getting out anywhere in the house…
Then the other thing which occurred to me is (and you can tell I know nothing about heating) doesn't the system have anti-corrosive stuff in it, which will dilute more and more every time I bleed the system?
What should I do please?
Thanks
