Leak in Open CH system

Postby aongus » Tue Jan 15, 2008 11:15 pm

Hi There,

I have a leak in an open CH system. It leaks something in the region of 1 litre / 10 mins when the system is turned off, when it's on, there does not appear to be a leak. Seems really strange to me. I checked the immersion tank which is a cross over point between CH and hot water system, I don't think it's leaking inside the tank, as the water is running in the CH tank while the hot water is not used.

I don't see any leaks in the house, so, I can only guess that it may be between the shed and house. I'm guessing that the heat is sealing the joint. Tried some sealer, which seemed to work but it's started again since....

If you can't find a leak how do you know it's 1 litre every 10 minutes? Something must have driven you to that conclusion and it seems like a good idea if you could share that data.

I'm already leaning towards the thought that you should get someone in to look at it.

If it was a sealed system i'd understand what you're saying - apart from the 1 litre every 10 minutes.

How do you know there's a leak if you can't find it, there's no signs of a leak ?
