Hi,
We locked in a favorable gas contract two years ago for Gas. Pricing for the fuel is much less on a BTU basis than #2 oil. I ran my three dual fuel buildings on gas-only last year & again this year. For the first time in 25 years – there were NO need for call-in or emergency service during the heating season. And this year’s clean, tune and start-up went very well, too. Joe is correct, gas is favorable now.
