I am looking for a factory-authorized/trained SERVICE person for my Bosch FHP open loop system. I am in lower Michigan. Looking for someone to take a look at my system - experiencing HIGH electric use and low Delta T and need to figure this out!! Does anyone know of a Bosch FHP person? I can't find anyone online? Thanks,
From your description of operation on other thread, you may not need an FHP tech - things are sufficiently out of whack that any geo tech should be able to quickly identify the root cause.
I agree with Curt, any good heat pump tech can help. I sent you a private message as I may not be too far from you and sell/install FHP relables. If you are not in my area I may know someone else who can help. Good Luck, Joe
