LPG furnace upgrade options
3,000 square foot house built in 1999 or 2000. Currently has 150k 80% Armstrong single-stage furnace and cheap 40 gallon water heater. LPG bills average about $2,000 per year.
Have not done a heat loss yet, but at 40 BTU/ft2 I'm guessing the furnace has to be at least 20% oversized.
Thoughts on a 90+ modulating furnace and a more efficient water heater vs boiler with an indirect and hydro-air? Other options to consider?
