performance with both oil and gas? I know the Buderus G-115 can also burn natural gas, but as far as I know the company has not posted at what efficiency. If they're within a few percentage points that would be good enough for me--great to have that option in a seesaw fuel market.

    I am considering replacing my oil fired boiler with a more efficient one. What are the most common issues, both short and long term with boilers? In other words what parts a likely need replacing? Are the parts easily found, especially for european branded boilers? I live in the NYC area.

    Which brands of boilers have historically been the most reliable? THANKS!

    Machinery is machinery. It breaks from time to time.

    In my experience Riello burners tend to last a great while before needing replacement parts aside from nozzles and electrodes. So long as there no chance of water in your basement, Riello is a very reliable burner.

    As far as boilers there are so many good boilers out there. Visit the websites of Buderus, Viessmann, Energy Kinetics, and others. Make sure your en educated consumer, and my best advice would be your confidence in your installer. The find a pro section of this website lists a host of first class craftsman for you to choose from.

    Good luck

    All of them

    All of the major manfacturers, Burnham, Weil, Buderus ect., make good reliable products. The major difference in the major brnads is the installer, a shoddy job is a shoddy job no matter what kind of boiler it is. The current 3-pass oil boilers on the market are all about apples to apples, I haven't heard any problems with any of them, you will get about the same efficiencies on all of them. The Mod/Con gas boilers is still a developing market and you will hear 15 different opinions on which one is "best", I would refer back to my previous installer statement on these. Just my 2 cents.
  • Jim says it's hot-water

    We've had good results with the Solaia boilers which are based on the Biasi casting. These are also 3-pass units, and can be fired with oil or gas by having a pro change the burner. This feature puts you in control of what you burn and at what price.

    The most important thing is a proper installation. Have you tried the Find a Professional page of this site?
