First convection from the air may be more effective cooling, and second the area of contact for a cylindrical hose is likely pretty small. > Its pretty much useless to try to use steam flow out the hose to estimate > heat output... > I think you're wrong. The equivalent area of a cast iron radiator at the same temperature, dissipates about 150 W of power into a room. I doubt very much that hose dissipates very much more than that. Especially considering it probably isn't even at 100C, considering Mats Lewan was able to handle it without protection.
