Underfloor heating

[armb]

Nu-Heat phoned this morning. Based on the samples of hose, they reckon it all needs replacing, and will start leaking everywhere soon, not just at the manifolds - basically the stuff they were using 10 years ago isn't up to the job, and deteriorates in the presence of copper. Most of the piping is plastic, but the bits near the cylinder are copper, like the cylinder itself. So are the manifolds - it might be possible to replace the manifolds and some more piping with plastic, but with the cylinder being copper it wouldn't help much.
They'd be happy to sell us a replacement system....

Thanks. In my case the system was in the house when we bought it, so we didn't have any contract with Nu-Heat, so I think the chances of any compensation are very slim indeed.
