Peerless 63 Series... Discontinued???

Saw in another thread the mention that the Peerless 63 Series boiler is being discontinued. Is that true? I don't have my ear to the ground but this is the first time I've heard of this.

Peerless does seem to have it on their website still, alive and well.

If this is true I'm a bit bummed. I have a 43 year old Peerless G-461 which became the 61 Series in 1984 and eventually the 63 Series. Runs great but at some point it will inevitably need replacement. The 63 series was going to be a one-for-one replacement since much of the piping will be in the same place.

Any more details on this? The Peerless 63 was known to be one of the better gas-fired boilers that typically last a long time.

If the 63 is going extinct… what is the best natural gas steamer these days?

***EDIT I saw that the 63-x is the new Peerless steamer. Not sure how I feel about a single supply and only 7 gallons of water capacity. I also don't know if I want to be a guinea pig either. And the controls/piping are on the opposite side. 😭

    The 63-x is the Burnham steam max or whatever they call it. Peerless is slapping their label on it. The documentation is nearly a 100% duplication of the Burnham docs. Apparently a pretty good boiler. I think it is a more modern design with one or two points more efficiency (not noticeable on your bill).

    Peerless hasn't said anything that would be heard by the public on this topic, as you say, their web site gives zero clues. The only clue I saw back some months ago was the mysterious addition of the 63-X which led me and others to believe the discontinuation of the 63/64 series was forthcoming.

    Now if you look at any of the big online suppliers, they all say it's discontinued as of August 2025

    Again, zero word from Peerless to the public. They are a very opaque company when it comes to the public. Maybe contractors and distributors have more information, I have no idea.

    I bet if you call around you might still be able to find one, and frankly, I would say that would be worthwhile.

    If I had to replace mine today it would probably be a WM or frankly maybe a Utica/Dunkirk which, even though it has the less-than-optimal side steam outlets, it is a very nice casting IMO and uses steel push nipples instead of WM's gaskets which my gut doesn't like as much (I have zero actual data to back up my gut feeling).

    The 63-X might be great, but I have a strong distrust of Burnham just due to the fact that they are STILL offering the IMO flawed Independence line which again, IMO, should have been re-engineered or cancelled years and years ago given how fast it seems to rust out.

     but I have a strong distrust of Burnham just due to the fact that they are STILL offering the IMO flawed Independence line which again, IMO, should have been re-engineered or cancelled years and years ago given how fast it seems to rust out.

    Me too.

    There was a post here just a few days ago about an independence that failed installed in 2013 I think the op said.

    They (all the mfgs) design a boiler that then go with that design for 20, 30, 40 years or more.

    The HB Smith 28 the first one I saw installed was 1977 and they still make them today. A few changes but the sections are interchangeable.

    Once they go with a design they ride it to the bitter end . If its bad they will still sell it and will only drop it if it will not sell.

    The Weil McLain Gold oil fired is basically the same boiler they have made since the at least the mid 80s. Even though it is rubber gaskets it seems to hold up pretty well.

    Utica/Dunkirk have been around for years as well. Any boiler can fail if neglected but they seem to hold up as well as anything.

    Peerless (or the Boyertown Foundry whoever that is) has been making the boiler sections for Smith & Peerless ever since Smith closed their foundry in Westfield which must be 35? years ago.

    Don't know what is going on with Peerless.

    I just got off the phone, with the Peerless rep. They are absolutely continuing to manufacture the 63 series. But they won't be packaged anymore. They will be knocked down. Which means that you need to assemble the jacket and controls yourself. Which for many of us in my part of the world, is a major upsell. Virtually every boiler that I bring in, a need to knock down myself. The boiler is simply do not fit properly with the jackets on. So in a nutshell, nothing meaningful is changing.

    Thanks @STEAM DOCTOR, that would explain why it is showing discontinued from all the big online sellers—they all sold the packaged ones.

    Does that mean that even the tiny 63-03 with just the two end pieces and one middle section will come on a pallet with all three sections separated and some rope and sealant and tie rods to let you build it all in the basement?

    No. Not at all. The block will come fully assembled. Meaning all the sections connected to each other

    Thanks again for that clarification. So just the jacket and the rest of the trim pieces, that's pretty good. Everyone likes Legos!

    Will need to field assemble the wiring. No big deal. The wiring comes marked. Not well, but if you look at the wires, you will see tiny notes as to which wire goes where

    First time time might involve a tiny learning curve. But it's really very easy.

    Thanks guys…this is great news! It will also force me to assemble the boiler myself which was not my first choice.

    At least I won't have to figure out how to get the assembled boiler down my steep, janky, crooked old bulkhead stairs when it comes time!

    And hopefully that time will be a long way away. Runs like a champ and shows no signs of slowing down. Impressive considering it is 42 years old and was completely neglected for the first 25 years of its life by the previous owners.

    Good that the 63 is still available.

    Timken does not make boilers anymore. You may need to do what timken owners do. Replace it with different boiler. Or you could be proactive and just buy a 63 now. Just keep it in your basement for another 30 years or so, until your G-461 fails.

    is that what the reader's digest complete do it yourself manual referred to as a "pot type oil burner" but offered no diagram or picture?

  • EBEBRATT-Ed
    EBEBRATT-Ed Member Posts: 19,881

    @mattmia2 A pot type burner used kero or #1 oil and was gravity fed from a 275 no pump. It had a constant level valve, and the fire didn't go out. It was like a lantern with a wick almost. When the thermostat shut it down the constant level valve closed down but not off and kept an oil pilot. When the thermostat called for heat, it opened the constant level valve and the flame increased. Perfection Furnace were the ones I saw.

    If it was Timken it was a different animal. They had a motor and it was a vertical rotary burner and fired straight up like a pot burner. The motor shaft spun and slung the oil out by centrifugal force.

    Timkiens (and there were other vertical rotaries like torrid heat) were very efficient burners. Better than most gun burners at that time. They burned clean with a high Co2.

    oh, the timken burner is like a blowtorch or coleman lantern/stove where it vaporizes the fuel in to a gas before burning it. I bet that makes a real mess if it doesn't light.

  • EBEBRATT-Ed
    EBEBRATT-Ed Member Posts: 19,881

    Pot burner just kept a small flame going and vaporized the oil based on heat.

    Timken or any rotary burner vaporized the oil by pumping the oil into a spinning usually tapered cup. The oil got slung off the cup by centrifugal force.

    Several of my childhood neighbors had Timken burners. They were very quiet, but they would start with noticeable blue smoke from the chimney for 30 to 60 seconds. IIRC that caused their demise, due to environmental regulations.

    They were all eventually replaced with gun burners.

    i'd imagine what happens when someone presses the reset on the stack relay 20 times when it finally does light off was their demise.

    i'd imagine that like atmospheric conversion burners they are kind of a pain to install and service compared to a power burner.

    I have a 22 year old burnham independence, I am trying to get a peerless 63-03, any insight as to who I might have to talk to or a distributor that would know what I’m talking about? I’m not looking for the peerless 63x.

    My brother in law works in the heating industry and has made several calls to a few distributors to inquire but none have panned out. I am in central MA.

    The Timken's ran with high efficiency. But gun burners used standardized parts and were easier to work on

  • bburd
    bburd Member Posts: 1,271

    These were warm air furnaces. Timkens were no longer manufactured by the time the heat exchangers failed after 20-25 years and they had to be replaced.

    @bburd I don't mind hot air heating.

    After all ,as I see it in the end even when having an oil or natural gas heater the heated water gets pumped in radiators and then heats the air(by natural air movement or special radiators with centrifugal blowers).

    And then start "the technical problems": on return in a normal non-condensing central heater the temperature must be 140 fahrenheit(60 Celcius) to prevent corrosion in the boiler...

    Then there's the condensing oil/natural gas heaters that MUST have return water under100-105 Fahrenheit(40 Celcius) to get the condensing process going and manage to get those few percentages of efficiency from exhaust gases...

    Might as well heat the air directly with a problem free burner(no nozzles to get plugged) or natural gas...

    I have no ideea right now ,as I write this, of the efficiency on a natural gas/oil heater that heats air directly but having had to deal with this water return temperature problem, might as well heat air directly.

    And no pipes, no 300 euros a piece radiators(for condensing units) for cooling fast the water to 35-40 Celcius, no corrosion problems ,no pumps, seems so good for me!

    But as good as gun type oil burners may be I had enough of that!

    Would love to see,have and use a rotary oil burner.

    Except Sunflame big ones, even on internet I can't find ANY smaller ones...

    A shame since they are simpler and able to burn higher viscosity fuels!

    Thank you!

    I heard Crown Residential Boilers were second only to Smith, which was considered #1 that sold the residential division, but I rarely see any mention of Crown Boilers on this site.

    @Gabriel82 , hot-air is the worst way to heat a building. The moving air makes you feel colder, it circulates dust, dirt and germs, and there is no radiant heat transmission (like the sun) to warm you directly. The only reason builders use it is because it's cheap- they don't have to live with it.

    Forced air allows for air conditioning, which also drives the decision to install it. You can add air filtration, filters, UV, and humidification for areas with that need.

    I don't feel as comfortable in FA homes, but 90% of the population may have never experienced a HW or steam system. So they have no real life comparison. I'd guess there are many more FA installers available also.

    Knowledgable Hydronic or steam installers are not so easy to find. Most are booked for weeks or months.

    "B" boiler in my opinion. Not is same league as Weil McLain, Peerless
