Do you have a link to it? I would like to see that. I came across something there a while ago but it sounds like what you mentioned is more recent.
What I saw, they were comparing temperature drop but it was at different locations that would have different type dirt and the pipe and pump size were not even the same.

Unless the pipe is in the exact same conditions and is flowing the exact same amount of water, using temperature drop will not be accurate.

Like I said, I haven't read it and know nothing about how they did the testing but what I mentioned above is the usual I have seen.

RSI,
   I do not have a link to the articles. I do believe it was from the hearth site, probably about 18 months ago. Those guys over there are fanatics, and most of them hate OWB's and anything OWB related. I use the same handle there, and if you visit there,you'll see they don't really care for me. They were talking temperature drops, but they were also measuring btu output verses btu's stored, and their formula's made sense to me. They were using weighed amounts of mc controlled wood and transferring to storage tanks, and that's how they came up with btu losses.
   I have 15' of triple wrap going from my boiler to my barn, and snow will melt off from it even with no sunlight. I also have around 10' of ThermoPex exposed, and snow typically won't melt unless it's exposed to sunlight.
   Scott,
That's the first time I've ever read the phrase "dinky dink". Funny.

Do you know what brand of triple wrap you have?

I will go out right now and look.

It does not have a name on it. It has blue and red lines with no insulation between them. The last layer is foil wrapped, but the rest isn't. Parts of it look like three wrap, but near the seam looks like five wrap. I bought it from our local Empyre dealer. He swears by it. I'll call him and find out what brand it is. It's too late tonight.

I think I know what it is you have. I will send you some pics tomorrow if I get a chance to see.
