Will all of this run on one 3/4" natural gas line?
I'm getting different opinions from plumbing contractors I'm getting quotes on to replace my old electric water heater with a gas tankless re: if a new line needs to be run from the gas meter to the new tankless (85' run) or if the whole house can run off the 3/4" line which is already running right next to the electric water heater.
Here's what I have:
Gas Furnace: 154,000 BTU
Gas Fireplace Insert: 40,000 BTU
Existing Gas Tankless Water Heater: 199,900 BTU
Additional Gas Tankless Water Heater to replace electic water heater: 199,900 BTU
Gas Clothes Dryer - ? BTU
Gas Cooking Stove/Oven - ? BTU
I already have e-mailed my gas company the same specs above for them to verify the meter is sized appropriately to handle the load but my question remains re: how do I figure out which contractor is correct re: if the one 3/4" line can handle all of this?
