Re: Need Advice About Switching from Oil to Natural Gas
If it's natural gas ( NG ) there is no tank involved -- it's piped to your home.
Other than oil the only other fuel that requires a tank would be propane (LP )
As for you radiator heat --- the natural gas would replace the oil as fuel for the boiler.
It would require to retrofit the boiler ( if it can be ) --- removing the oil burner components and replace with natural gas burner components.
