Need the age of this water furnace if you can help!
This TPR setup just looks wrong…advice please. The discharge pipe is condensate hose which I have called out as I cannot see the termination point it just goes into the wall!
1986…
What is the age of the home?
Many water Heaters were connected to Geo-Thermal Units but these were Water Heaters designed for that application.
The piping may be related to the Geo-Thermal Unit but is not a typical installation (thermal loop piping).
Recommend review and repair…
The tpr can be installed like that if it is a longer thermometer on the bottom. Check out the third pic here. http://www.watts.com/pages/support/tp.asp?catId=64 That hose is not the right material no matter where it discharges.

:D:D You Guys are awesome!!! Sorry Joe I don’t know the age of the home, MIC for Realtor listing …he was not around ( a foot of snow today) and the listing has not been confirmed. my check is 
Normally on a water heater being used for hydronic heating, (if that’s what it is) the safety valve is pressure only activated @ 30 psi, not a standard pressure-temperature valve like used for a domestic a water heater even though it is the same appliance, only being used for a different application.
