Any thoughts on the use of a stainless hose clamp with radiant heating lines?

Looks like a place for a leak to me Wayne.

Every time they tighten that clamp up they are destroying the fibers under it.
Won't take long for it to break down.

I personally wouldn't feel comfortable if that was in my home.

Yes I agree. The rated clamps are attached to a specified tension, a hose clamp would normally be overtightened.

Even though it may be wrong they use them on radiators on cars that can get extremely hot. They are also been used on older homes connecting well components. They use them on hydraulic hoses under allot of pressure.
Just playing devils advocate.

Onix radiant heater hose has some very specific installation instructions and cautions about clamping.
Here's a link
http://www.wattswater.ca/pdf/OnixInstallationManual.pdf

search through the PDF for "clamps"
they even have a pre set torque tool.
As a matter of fact here's their language concerning "other clamps"
"Connections made with barbs or
clamps supplied by other companies
are specifically excluded from any
Watts Radiant warranty coverage."

Yeah, but a leaking hose in your driveway is not going to create as much concern as a leaking hose in your house. :)

I had allot of junkers in my youth and leakage usually occurred from deteriorated hose or pin hole in the radiator. Never had a clamp failure but I have had them leak at the connection but that was due to split or deteriorating hose not the clamp. :)

Precisely.

That is what is being referred to: that clamp on that hose, and when the hose deteriorates, that clamp will still be there, nonetheless, though, you will be looking at a clamp and hose which is leaking.

'Of course' *the clamp does not leak* ... :) ... it is the hose which leaks. :D
