Hi folks,
Basically my question is "Where is all the water going?". My heating has been getting noisy recently. It's a sealed system and every 6 months or so I have needed to repressurise it up to 1 bar through the filling loop and drain a couple of radiators. However, it got very noisy and on checking there was no pressure registering. Filling it took ages, as if the system was basically empty. Then, 2 days later it was noisy and showing zero again. Refilled and this time it lasted less than 24 hours. My pump then failed, which suggests to me there's no water in the system.
I checked and it's not all coming out of the pressure relief valve. The heating isn't on, there are no water stains on any of the ceilings, there's no obvious damp smell anywhere downstairs. The drain valve doesn't look as if it's leaking or anything.
Is it possible that the heat exchanger in my very old outside Kingfisher II boiler is cracked and it's all boiling out that way? Anyone have any other suggestions as to where it's going or how to find out?
Thanks
Matt
