I live in TX and have Amica as my natural gas provider. I want to replace my tank water heaters with a tankless unit. According to the Amica tech, I will need an upgraded gas meter which would increase my home's gas line from 0.25 to 2 PSI.
He also said once this happens, I'll need to make sure I have regulators in place at each of my gas appliances to make sure they don't get damaged from having too high pressure gas coming into them.
I can't seem to find any other information that mentions this. No YouTube videos besides people replacing bad regulators and no posts anywhere. Am I missing something? Do I need to install regulators before these appliances so they don't get overwhelmed with the increased gas pressure?
My gas appliances are my kitchen stove, furnace, and fireplace as well as the two water heater tanks to be removed soon for the tankless unit.
