what temperature of water do you need for a heat exchanger
Obviously, this system requires a very reliable circulating pump to keep water flowing properly throughout the loop and to allow for the proper transfer of heat energy. The two basic requirements of this pump are to guarantee adequate water flow and to maintain the water temperature between 60Â° - 90Â°. To keep the temperature within the range, the system must have two additional components-a supplemental heater and a heat rejector or evaporative cooler.
