I am working with a contractor to install a tankless natural gas water heater that requires a 3/4 gas line and 199k BTU.
I have two half inch gas line terminating around the same area in my basement. They were previously used for two furnaces. I have since moved to geothermal and these furnaces are no longer there.
Each of these half Inch gas lines by themselves do not provide enough gas for the tankless water heater.
It is possible that these two gas lines can be combined using a manifold into a 3/4 line and then connect that to the tankless water heater.
I understand it will depend on the incoming pressure etc, but will this combined line theoretically have better supply and pressure compared to a single half inch pipe.
