We have an eight year old geothermal open loop system in a 90 year old house. A newer bigger (3/4Hp) submersible pump was installed before we put the geothermal in. We have short-cycling issues basically whenever the water is running. We have replaced two bladders to no avail and a pressure switch. The current recommendation to fix our short-cycling problem is to install at constant pressure pump for $. I read varying opinions here and don't fully understand some of what I am reading.
Could short cycling be caused by a clogged heat exchange? I would appreciate any suggestions from knowledgeable people on the constant pressure pump solution, since the attempts so far with the bladder and the switch have not helped.
