geothermal hvac with dsh
I am about to install a Geo system with a desuperheater. I understand that I need to install a buffer tank and supply the regular hot water tank. Am I right in thinking that I Marathon with better insulation qualities is better, or should I save a lot of $$ and get a brand name whatever 85 gallon tank with a decent warranty? Also, if the tank is not powered, will the water still destroy the anode?
Not sure if this question is better handled here or in plumbing....
