Hello,
We Just moved into a 45 year old house in Montgomery County, Maryland with an oil furnace and I want to convert to NG. Washington Gas needs to know if I want 0.25 psi or 2 psi delivery. I will have a 90K BTU gas furnace and 80K BTU range (these are both approximations); no other appliances are planned, for now. A contractor suggests the 2 psi option in case I want to add other gas appliances in the future. Does this sound reasonable? If I were to add a 40K water heater would that mean I would need to have a 2 PSI line? Obviously, I'm just learning about this subject and any suggestions would be appreciated.
Thanks.
Richard
