Great idea .  But if it's loosing heat for the 12 hours you use it . Why not just Insul seal it and be done with it .  I have 50 feet of Insul seal on one of my zones temp drop is undetectable .  And a 130 foot run sprayed in polyurethane 4 inch on 3 side 10 inch on top with pex Al pex .looses about 1.2 degrees after 23 years in heavy clay .  Other run I have is 110 feet looses 1.1 degrees after 23 years .. So story is you need 2-4 inch polyurethane and water tight once have that you can bring heat Los to minimum.  I tested mine in winter . Not on hot summer day . Cold penetrates a lot better than everyone thinks. 👍😳 It's shocking .
I feel pretty lucky spray in polyurethane still hanging in there after 23 years .  Back when I installed spray in polyurethane was cutting edge .

That heat loss in the ground is precisely why I've decided to put a plate exchanger in the back of the boiler cabinet and pressurize my underground lines with glycol with another pump in the house, so the underground only circulates on call for heat. Which, on sunny days, is never. If I can drop my circulation time from 24 hours to 12 hours, my math says that comes in at roughly 2 cord of wood saved per season. That's with Logstor

That would be genius, how would you accomplish it?

I like how you can really nail down the worst winter . It justifies why certain years took so much wood. Looking like 2018-2019 going to be for sure be in top 5 of last 20 years.

Using the Heating Season instead of Annual gives a better indication of the winter.  For me it looks like 2013-2014 is the worst with 10,760.

Using a 3 way light switch I've wired the power to the oil burner so it either starts a separate pump that pumps a loop through the flat plate, or runs the oil burner. Can't do both. Manual either-or switch.
Also done the same with a Ranco temp control sensing owb temp.
Basically what I'm saying the oil doesn't have to be kicking on.

I found a better site weatherdatadepot.com to figure out heating degree days . Yes in ground heat loss is evil . I'm loosing 2.03 degrees in 274 feet in the ground 3 zones. This charts at 63f and just look how nasty 2013 and 2014 was.

I was just thinking another variable is heatloss in the ground. I would think that is somewhat constant throughout the heating season. That may be need to calculated separately.

This is bothering me. What the heck is the red cast iron-looking unit on the floor inline with... something.

I believe what you're seeing is the top of the fuel filter.
