We have an endless supply.
When we first bought our home, it was equipped with an oil furnace. It was toward the top of our improvement list, but unfortunately some other projects took priority. We had a leaking roof that was causing a great deal of property damage. The new roof was a big expense. We also decided it would be smart to implement some energy saving measures before replacing the furnace. Tightening up the house allowed us to purchase a smaller heating system at a lower cost. We invested quite a bit of money into upgrading to Energy Star rated windows and insulating. It took us over five years to switch from an oil furnace to a natural gas furnace. Along with the cost of the heating system, we had the expense of conversion. However, the investment was definitely worth it. The oil furnace required a very large and unattractive tank that sat in our yard. I worried about leaks and contamination. Plus, I needed to schedule fuel delivery. There was always the concern of running out and ending up with no heat in the middle of a January blizzard. Natural gas is much cleaner, convenient and environmentally friendly. We have an endless supply. The new gas furnace achieves a 98% AFUE rating and provides ideal comfort no matter how cold the outside conditions. Because we now have access to natural gas, we’ve been able to convert our oven, clothes dryer and water heater. We are planning to hook up a natural gas barbecue that will eliminate the need to buy propane tanks.
