supply line

Bob_115 · February 2025

will a 3/8 copper line supply enough gas for a 120000 btu tankless water heater?

pecmsg · February 2025

what gas?

What pressure?

How many bends?

Propane maybe depending on the answers to @pecmsg 's questions , methane, no.

Absolutely not at 11" for propane. 1/2" copper wouldn't even do it at any length.

Hi, What size gas pipe does the tankless manufacturer ask for? 🤔

Yours, Larry

3/8 acr will do it with lpg for about 30' at 2 psig so we need more information like @pecmsg 's questions.
