    Correct, we only run one tower pump and one loop pump at a time. We have two pumps for redundancy.

    Yes, I verified the cold water from the tower is coming in and is plumbed up to the exchanger...

    As promised, here is the data and some pictures.

    I have collected 24 hours worth of data, my meter recorded the temperature every 30 seconds for 24 hours. Then I downloaded the data into excel....

    Tomorrow, I will get a picture of the heat exchanger and provide some data

    Thank you for the information, I really appreciate it.

    The picture you provided, I am assuming that picture was taken just inside the heat exchanger tubing looking down the plates? The ... rocks...
  9. Info

    Geo loop? I assume you are referring to a geothermal loop? If so, no we do not have a geo loop. Just the cooling tower.

    The pipe that burst was a plastic 2" pipe at a fitting. We ended up...
  10. Question - What would be a good healthy water...

    Question - What would be a good healthy water temperature to see coming from the heat pump while in cooling mode? I think the heat pumps start locking out when the loop gets near the 93 degree mark,...
  11. Sensors

    Ah, I think I now understand.
    Basically your advise is to have sensors and controls in place, should a leak/malfunction happen, shut down systems and waterflow to reduce the amount of damage,...

  14. Pumps

    No, we have not been able to check the flow rate from any of the pumps. There is not fittings on each side of the pump to plug into. To install fittings, we would have to drain the tower and the main...

    I measured our heat exchanger, it measures:
    19 wide
    57 tall
    10.5 deep

    My only concern wish acid clean is the cost of cost and labor of flushing the heat pumps vs. the cost of replacing the heat pumps.

    The other recent theory I have thought of is - Air in the main...

    The pumps are pumping, we checked the amp draw and they are pulling about the right amount of amps (I forget the readings, I have them at work) But for 5 HP motors, they were pulling about 3/4 load....
