I recently had a Carrier geothermal system installed in my new home.
The question I have is about it producing hot water. There are 2
pipes that connect to my hot water heater going into the system, HWG
in and HWG out. The HWG in comes from the bottom of the hot water
heater and the HWG out goes to top of the hot water heater. I've been
unsure if the system is producing hot water like it should. The top
pipe comming out of the geothermal system is always either the same
temperature or colder than the pipe going in. I put a temperature
prope on it to test it. Would this be right, shouldn't the top pipe
coming out be hotter than the pipe going in? I tested it for several
days now all throughout the day and this seems to be happening, even
without running any hot water. It seems though that when we do run
hot water, the pipe comming out of the system going to the hot water
heater is very cold, yet the pipe coming in is hot to the geothermal
system. Is this normal, and how else can I verify that the system is
making hot water?
