HOT WATER SYSTEM QUESTION
HOT WATER SYSTEM QUESTION
(OP)
While we are flushing our HWT system with domestic water for two day in a row, I noticed that the temperature of the circulating water just increased. I do not understand how this happen because we bypass the heat-exchanger in the system so the water is only circulating from the pump to the branch line going to AHU's and the coming back to the pump. Is there an explanation about this one? Can somebody tell me what just happen.

"Is the water going THROUGH the AHUs?"
Oh sorry I have to correct that because actually the AHU's are isolated so the water is only circulating in the piping network. Is there a relation between the increased of the temperature of water and water going inside the ahu's?
RE: HOT WATER SYSTEM QUESTION
Isn't the whole purpose of running cooling water to the AHUs to transfer heat from them? Are they located on the roof; exposed to sun? Are the pipes leading to them exposed to sun or warm environment?

RE: HOT WATER SYSTEM QUESTION
is your heat exchanger ON or Off, is there any possibility of water to leak through the exchanger?
