Originally my installer indicated he was going to use three wells at 200' deep for my new system. He even laid out the well locations with some surveying flags and had three locations marked. The well driller called me this afternoon to make sure he was at the correct house and he said he was told to drill 2 wells at 310' each.
I know I'm ending up with the same footage but I was wondering if the number of wells and their depth affects the performance or the operation cost of the system. Will the pump use more energy since it has to pump up 300' instead of 200'?
Total footage of bore hole is what is needed. 3 shallow or 2 deep will give you the same performance. Since the loop is closed, it takes no more pumping energy to go 200 or 300' . The pipe diameter comes into play. 3/4" is OK for a 200' well. 1" would be needed for a 300' well.
Hope this helps.
