We have a 5 year old Buderus G115/5 boiler with a 5 year old Riello 40F5 burner.
Can this burner be converted to natural gas?
Will it be more or less efficient? We really want to change over to natural gas because of the crazy high prices of oil. People keep telling me that natural gas won't keep our home as warm, which doesn't make sense because it's heating water in our pipes. Please advise. Thank you.
