so the well driller showed up today and did the water test on my well water... first of the damn thing bubbles methane... you can on some burst of the bubbles from the overflowiing well head (yes the well head is 620 feet and flows out at about 1-2gpm) light the top of the water (the gas bubbling out). here is the list of water quality that they handed me hardness 11gpg iron .2ppm ph 8.0 sulfur 20ppm tds 380 pm methane present well (no pun intended).. most of the heat pumps state no levels of hydrogen sulfide (sulfer) permissible. water furnace has a sheet on they're site showing this chart.. cupernikel will work but from what i read on the whole sulfpur thing it wont... http://www.waterfurnace.com/literature/envision/IM1006WN.pdf page 6 shows that 10-50 ppm of sulfer is ok??? i wanted to feed my pump with the 52 water that i am getting out of this well and not have to do anything to it but what all do you guys think. My installer buddy says that we can just put a stainless heat exchager before the pump and close the loop to the pump? how much work and cleaning is that mean? extra money? the well driller thinks that we might have to put a loop inside the well and just call it a closed loop altogether.. do i have anough depth? 5-6 tons he says that the loss of the use of the well pump .5hp and going to a small circ for the closed loop will make up the effiency of the standing column loss? what to do? what to do? thanks you geogods!!
