Is the waste of money for a duel fuel burner running only oil due to the burner cost or other efficiency costs?
Is a power gas burner more efficient that a normal gas burner when burning gas?
How does one best utilize the duel fuel? run a mixture of both? Switch from year to year?
What is the current thinking on gas versus oil for a steam system?
I currently have a pre-1920 7 chamber boiler originally designed for coal. Anything else to watch out for when replacing this boiler? I know dealing with the smaller volume of water is going to be an issue.
: : When you say "power gas burner" is that different that a normal gas burner?
: ++"Normal" (the majority of) gas burners are ribbon burners arranged in rows under an exchanger. A power gas burner is built like an oil burner, with a fan to mix air with gas. That's why you get one burner for gas and oil as a dual fuel unit.
: : Is it much more expensive to go with a duel fuel burner and only use it for oil?
: ++ Yes, that would be a big waste of money.
: Any other downsides such as less efficiency?
: ++ No
: Is boiler efficiency burner dependent?
: ++ Of course.
