Mom & Dad had their propane tank(s) filled in the fall for $1.67/gal. They can run about 11 months on about 800 gallons of propane.
Cecil, now would be a perfect time to clean out the geo lines.
I had an old 40 gallon water heater and going to a whole house on-demand heater saved me quite a chunk of change. Putting in the fireplace insert saved more $$. I paid for the insert in 2 years by the natural gas savings.
