Hello to all. got a question. i have a boat that has a geo therm sytsem to heat and cool my boat. Can I do the same with my house geo system. would the salt eat the unit up? thanks leonard
I have several systems that use salt water. The one big problem is that all the rules that apply to boats need to be applied to the units. No dis simmilar metals ect. corrosion being the biggest issue with fittings and connections, not the coils. The cabinets have also taken a beating do to the salt content in the air, in the building.

does using salt water effect the warranty? how about efficiency of the unit? could this be open loop? thanks
I had a buddy buy a new corvette. He changed the tires and went rally racing with it, it was not covered under warranty, but he still serviced it regularly. Eric
Hey Waterpirate: would you use the same system for salt water, that you would use for an open loop? i would like to try this on my older system upstairs. that would take the load off my domestic requirements plus save the drinking water. any ideas thank you. leonard
I would run salt water through a cupra nickle coil or better only, I would never admit I used salt water to the oem manufacturer, I would pipe it in pvc only, not metalic transition joints, also be aware that water with high salinity is also abrasive at turbulent velocities. Your piping schedule neds to avoid 90's at all costs. Eric
Hey Waterpirate: what type of pump did you use in the salt water installation? What part of Maryland? I live across the river from Maryland. The creek I am on is brackesh. thanks leonard
I am actually in Delaware, but we serve the entire penninsula from cecil county down to cape charles. The first pump set up was 3 grundfos sqe pumps in each of 2 eight inch wells, for a total of six pumps. They all bricked and grundfos threw me under the bus. That is another story. The sqe's were replaced with low pressure high volume franklin electric pumps with sub drive 300's, one in each well and I have not been back in 6 years. This system runs on salt water not brackish, when I tested them post drilling it pegged my TDS meter at 1200. Eric
so as i understand you still drilled wells. i was wanting to pull from the saltwater river in front of my house.
What will you do to freeze protect the suction line from the river in the winter? Other than that a pump is a pump, I would reccomend one with brass or bronze inerds for dealing with the salt. Eric
