Best furnace for well head gas
I wanted to replace my 35 year old furnace and wondered what the best furnace is for well head gas. I have had my old furnace on this well for entire life. I was worried a newer furnace might have trouble with the gas. I have a regulater set for 2 OZ pressure. If we have a week of -20 (Which we haven't had for many years) the pressure will drop below this. Mostly I have 20 LBs pressure.
Would 80% or 90% work better? Is there a brand that would work better? Will I need a filter for the gas with a new furnace?
I have two drip legs on the line.
