No, but he just went through record warm October.

With that said, remote installs are less likely to have out fires due to the parasitic load of the underground piping.

Is that difference measured with a NON-contact infrared thermometer reading?

If it is, while comparing blue and red colored PEX it will not be apples to apples as it is a measurement of reflection and different colors reflect differently.
There could even be a possibility with certain colors where a combination could show a Heat Gain in temp, and we know that would be unlikely while traveling a distance buried underground.

Guess I'm saying wet well thermometer is one way to real proof. ;)

It shows the same temp difference on the black iron also, and good luck reading any mechanical gauge Down to the degree or half a degree lol

Coal consumption over time will eventually tell the story of the underground losses. But for this case there is no history by which to make comparisons.

If you assume 5 gallons per minute through your loop, that 1 degree drop will lower the boiler temperature about 5 degrees per hour. That is assuming everything else remained constant.

My point is that a boiler on a loop like that will fire more often to maintain temperature than one just sitting idle with no attached load.

The underground loop is a great substitute for a "hold fire" (or fluff) timer. It's consistency is like clockwork. Perfect for Mammoth vane coal.

Yes, and that is with everything remaining constant, and all the black iron is uninsulated, and the water to water heat exchanger is uninsulated also, something I have to work on.
