Hi, I'm new here...need a steam, gas fired boiler installed... I could have sworn the plumber was installing Weil MnLain...buthe's now telling me it's SLant/FIn. He says they are a very good boiler. Origionally I had Wel McLain lasted 23 yrs the Peerless lased 9 yrs (they wouldn't honor warrenty)...now I'm afraid with the SLant/FIn as I've nerver heard of it. Any input wouod be greqatly appreciated...

    We install quite a few Slant/Fin boilers. Good product from a good company. Be sure they follow the installation instructions to the letter, as with all boilers. In particular, the steam header needs to be at least 2-1/2"- do not allow them to reduce this size.

    Also- why did the Peerless fail? Did it crack, or rot out above the waterline?

    @yazz100

    Take @Steamhead advise seriously. The pages of this forum are filled every year with installations gone wrong.

    You don't want to be on that list.

    Most installers (and yours may or may not be one of them) will tell you they have been doing this for 40 years and for 40 years they have been doing it wrong. Happens that more steam installations are done wrong than are done right

    Peerless, Slant Fin and Weil mclain are all good boilers if installed RIGHT.

    When you know what boiler he is using download the install manual and read it there is a piping diagram in the manual he must follow....no cheating on pipe size etc. And the boiler must be skimmed.

    Also, it would be a good idea to calculate the EDR of all your radiators to make sure you get the right sized boiler...we can help if you don't know how

    Your installed should have already done that.....if not I would be extreamely cautious about using him

    Hi, Thank you... as a 67 yr old feamale, trying to make sure things are done properly, I do appreciate your speedy responses. Yes I've read that a boiler is only s good as the instillation... with that said I have changed plumbers due to the origional plumers lack of correspondance...it literally took him from late Feb to early June to give an estimate ( I "gently" contacted him 5 times on this in order to get any response) and then another 2 months to give specs of the Utica boiler he intstalls (had to bring up concerns of a timely installation given response times)...BTW it took him 3 months to even contack Peerless regarding the warrenty...Needless to say, I felt like he didn't want the job and startrd looking for another plumber. The new guy I fund was recommended by numerous people in town. He did size the radiators etc for boiler size. I will certianly take your advice and manual downoad for pipe size etc.

    The Peerless cracked after 9 yrs...I had it serviced annually...Peerless said the boiler had oxidative corosion which voided the warrenty...with that said I asked my plumber what would have caused the corosion...he said he didn't see anything that would cause it except possiby the automatic feeder or if I had hard water. Obviously I am concerned this will reoccur with a new boiler, so I'm thinking of disconnecting the automatic feeder (although concerned what happens if I go away for any length of time in the winter...no one here to check water levels). He also said adding water softners can help, however I don't have hard water form what I can tell...no mineral deposits on shower head faucets, etc...so not sure about this or if it is good just as a preventive (suggestions welcome!)
    Thank you :)

    Argh... well, first, do NOT use softened water in a boiler -- the stuff is remarkably corrosive.

    Second, how much water is being fed? If you are feeding more than a gallon or so a month, you have a leak somewhere in the system -- or leaks (the most common culprits are the radiator valves) -- and the added water will cause excess corrosion. The automatic water feeder may have a counter on it; if so you can easily see how much water is being added.

    Where are you located? We may know someone knowledgeable in steam in your area.

    @yazz100

    It's important to know how much water is added to a steam boiler. Excessive amounts of make up water brings new oxygen into the boiler and causes corrosion.

    As @Jamie Hall mentioned some of the modern feeders have a counter that will read out how much water is added over time.

    You could have a moderately sized leak somewhere or a bunch of small leaks (air vents, packing nuts etc)

    First thing I would look for is to see if you have any underground wet returns. Look around the back of you boiler and see if you have any pipes coming up through the floor. They can be the source of leaks.

    In general a water leak you would see a steam leak you may not see and leaking steam means losing water

    HI I'm in the Hasckensack NJ area...If you do know anyone here I
    d appreciate the recommendation. Got it thanks...water conditioners are a no go.
    I don't have any steam leaks I know of...and if it's hidden then I wouldn't know. My plumber said there weren't any in pipes near the boiler. The water feed does have a counter I'll check it....not sure if it's dated though. ALl I've seen was a run of numbers

    Water softeners are wonderful. If you have hard water, your dishwasher, washing machine, and water heater will all last longer if you supply those appliances with softened water.
    This DOES NOT APPLY TO BOILERS.
    Water softeners add sodium to water. Sodium is inversely soluble in relation to temperature (unlike calcium and magnesium). At the higher temperatures of your boiler, the sodium will stay in solution, and cause corrosion.
    If you have a water softener, feed your boiler un-softened water, by piping it upstream from the water softener.
    There are special water treatment systems for boilers. These DO NOT add sodium to the water.
    If you do have hard water, you may want to have your installer do the initial fill of your system with water that has minerals removed.
    The installer should also repair any leaks in your system. Doing this will reduce the amount of make up water required during operation. Make up water has oxygen. Oxygen also causes corrosion.

    The hard water and excessive usage is disturbing.
    Have a water meter installed so the actual usage can be tracked.
    @JohnNY , @clammy and @EzzyT are the ones you want!

    Thank you all for your advice...I do have an automatice feeder but I don't believe it has dates, just numbers. I went to look at it but there backlights are off...ok I admit I'm not very good at all this lol

    @yazz100. Don't be so sure that you don't have leaks. Steam leaks can be hard to see. Not uncommon that I get calls from customers who are convinced they do not have have any leaks. Between main air vents, radiator air vents and radiator shutoff valves,  I often find 10+ leaks. And these are in small residential homes.

    I do not see a lot of Slant Fin steam boilers in my area. But they do seem to have a rather short life. 15 years seems to be normal. But again, that is from a very small sample size and certainly possible that there were other factors in each scenario.

    I undersatand and brought that up to my plumber...
    The origional plumber stood by the fact that he said there were no leaks..but the new guy said he'd have to wait till the heat is going and hes checking vales and possible leaks.
