RE: A Deeper Look At Shallow Geothermal - Part 2: Horizontal Optimization
I also had an article about house heating and I really think that your article complements it nicely. I was more superficial about this type of heating but I would advise my readers to read yours, this is why I will resteem it :D
It seems original and I have enjoyed it.
A nice curiosity (I don't want to imply anything) is that I have seen more and more people using offline references, while I am 100% online reading and referencing.
What makes you lean towards these kinds of studies, are they more complete or why would you prefer to pay for them?
Keep up the good work, now I need to read the first part as well :P
