Heating Oil prices have us looking for ways to reduce the cost of heating our (built in 2021) 2,000 sqft home in North Pole AK. We have Radiant Floor Heating from a Toyo Boiler in the garage currently. I'm trying to scope out if converting to Natural Gas (pipes installed on our street before winter hit) is going to save us money over the next 4 years, or if we wouldn't recover the costs of converting within that timeframe... What information do I need to provide to give you experts & intelligent people what you need to make a decent guesstimate?
