Open Loop Geothermal Heat Pump / Closed Loop Geothermal Heat Pump

« on: November 03, 2016, 11:47:05 PM »

I recently finished building a house and installed a closed loop geothermal heat pump system.  We have a two party well, only party on the well right now, and our water pressure maxes out at about 45 psi at the house.  The well house with two 80 gallon tanks is 160 ft. away and is only about 4-5 lower in elevation, and 1" water supply to the house.  The well pump is a 5 horse pump, pulling water from a depth of about 380 feet.  My pressure switch is a 40/60.  My issue is that the heat pump requires a water pressure of 50+ psi to run the geothermal heat pump.  How do I get the water pressure up to fully pressurize the system, and enough water pressure to run the house and a future irrigation system?  Is a CSV the way to go, and can it be installed at the well house?
