Been hearing pros and cons of both. Which is preferential and why? For service, reliability and efficiency?



  • Which models?

    Gas or oil? Chimney vented or direct vent? Steam or water?

    What type of system will it be connected to?

    Noel .. he'll vote for SlantFin

    Ask Glenn Stanton ... he'll say Burnham

    Scott says they are both good boilers and you should pick the best installer.

  • Scott's right

    Both boilers are cast iron, assembled with metal push nipples, and are offered with the same burners, pretty much.

    The difference is support, mostly from the installer, but also from the manufacturer.

    That's the part that I do.

  • And

    that is the part that I do too! Hope that helps!

    Noel & Glenn Great timing only !

    under 1/2 hour response from both. Must be to hot for golf.(hehehe)
    Anthony, I have installed both and found both to be good, But like Scott said I have seen both messed up by installers. Go with a installer you trust,most will install what they really like and trust. John@Reliable

    Noel and Glenn are two of the best- just like their boilers.

    You can't go wrong with either manufacturer. But the installation is just as important as the boiler. Go to the Find a Contractor page of this site to locate a good one near you.

    Do your homework

    I can only add that Noel and Glenn are two of the best. Also, as steamhead indicated, do your homework on the installers. This is what will truly make the difference in your level of comfort when all is done. Also, use this site as a sounding board once you have chosen your installer. In other words, ask these gentlemen what you should ask and then tell them what the answers were. You will not go wrong.

    Good Luck!

    There was a time when I liked both. I now feel since it's the year 2003 that something even more eff like Buderus, Viessman, System 2000 are what I like to see as replacements and definately in new houses. Both Slant Fin and Burnham have had problems with their castings but from what I've heard that has been rectified.
    If you're going to replace a system and you are staying in that house get the best you can. It will pay you back.

    Just a quick question Geno

    When and what type of problem did Slant/Fin have with their castings?

    a new one on me too! From what I've seen, both Slant/Fin and Burnham boilers last very well. I don't recall ever replacing one unless it was a steam boiler that had been dry-fired, which is not the boiler maker's fault. What's the story?

    Slant Fin leakers

    I installed a bunch of Slant FinL-30's at an oil co I worked at in western ME. We had a lot of leakers!! This was in 95 and 96 I am sure if Noel had been working at Slant Fin then, this wouldn't have happened!!

    I have seen way more v7 Burnham leakers.

    You asked.

  • Burnham V-73 Leakers

    I could hardly believe my eyes. The two fine gentlemen who represent Burnham and Slant fin boiler asking for more information concerning the possibility that a certain model boiler might have some casting problems. I stopped selling and installing Burnham Boilers for that very reason. I replaced 3 Slant fin boilers for the same reasons. This is a subject that could open a pandoras box with those of us with this unfortunate experience. They may have rectified these casting problems. Perhaps Burnham and Slant Fin could clarify what happened and then we can move on.
  • Hey Dave

    Just to clear the air, I did not question any comments regarding castings, Steve did. As you and just about everyone else here on the wall knows, we did in fact have some difficulties with our V7 castings prior to 1997. There were stress cracks occuring on the hot water boilers due to possible metal fatigue and increased firing rates more than anything else. The problem was remedied in 1997 and the V7 was replaced by the V8 in 1999. The V8 is a completely redesigned section assembly that is free of any stress and is also Energy Star complient. As you also probably know, we have stood behind every V7 boiler with a program in place to handle any warranty claims with a replacement jacketed block. This program also has it's own 800 number to process these as promptly and effortlessly as possible. I am sorry that you choose not to sell our products but that decision is completely yours. But the point I would like to make here is that we have not and will not bury our head in the sand regarding this issue. We will continue to take the bull by the horns and stand behind our products all the way. Hope this helps.

    Spoken as

    the true professional you've become to be known as Glenn.
  • Burnham vs Slant Fin

    Anthony, My recommendation would be Buderus. Having been in the Fuel Oil Business for over 24 years we have serviced almost every boiler brand manufactured. I came to the conclusion that from a quality stand point Buderus Boilers rank at the top of my list. Find someone in your area who installs them and make your own comparison. Incidentally I installed one in my own house,my office and my mothers house. Terrific product. Think Buderus.
  • Hey Glenn

    Bull and Horns, that was my experience with the V-7. You have a way with words.

    Casting problems

    S/F Had quite a few in early 90's? One was knocking like drums, air was trapped inside. Had a few crack at the back of the chamber above the target wall. Seemed to be mostly problems with the back section if I remember correctly.
    Burnham, I liked and haven't had a problem but the guys I know in the field have said they are having too many cracked blocks and won't install them anymore. I was pretty shocked to hear that but I've heard it from many different sources.
