I have a problem that I am not sure how to begin diagnosing. During the winter/cooler months when our furnace is running, we have a lot less hot water. Both the water heater and furnace our gas. They both reside in the same closet and share a gas line that comes in and "T"s off to supply gas to each appliance.
Has this been heard of by anyone and any suggestions on what the culprit maybe? It really seems like the furnace is "stealing" gas from the water heater. The pilot light is never out, so it is getting gas.
Thanks,
SB
