I have 2 water source heat pumps that require 18 gpm. They are fed from the same well that feeds my house. The well is a 4" well 170' deep with a 1 hp submersible pump hanging 40 down in the the well.
I would like to either drill another well and use a 1/2 hp pump or put another 1/2 hp pump in the same well to save electric costs.
Can a 1/2 hp pump supply the volume I need? Would a jet pump on a 2 inch well be able to supply the volume?
