Who has already installed a DX GSHP?
And more specific, who already made a DX with boreholes?
What about the coil: protected or bare copper?
If bare copper, was an acidity test performed of the soil?
Is there a noticable drop of R-value with the protected copper?
Is powder coating, metalising or galvanising a coil, then not a better option?
Who already used and installed cathodic protection? This technic seems very easy to use.
Does anyone know a supplier of protected copper? Som of them are located in Italy.
This was a topic in another thread but perhaps more will read these questions here.
