    Are there any users here?

    Are they white tag certified?

    Ball park cost for unit?

    Are you running with additional storage?


    Thanks

    Hi
    Second season with a 200,with 1000 gal storage. Unit was around 10K.
    Not sure on the white tag.

    interesting! not much of response to this one.
    I guess the outdoor model was not as popular?

    I think most people end up putting gasifiers in their house or a small outbuilding. I believe Salecker's is also in a building.

    Thermal storage really makes these boilers convenient. With that, you start fires more often. It is really nice to have nice dry wood, a warm building and fluorescent lighting when you are tending a boiler. It may sound like a pain but I timed my typical start and it takes 5 minutes and I am pulling the damper closed and done.

    Could I do it outside yes, would I want to no. With a indoor install if done properly you can leave your boiler and go on vacation. Both ends of my underground pex come up into heated space and the lines are buried under the frost line, no glycol is needed.

    Hi
    Yes mine is in a building.At the time the outdoor model was avilable,and i wasn't sure if i would get the building finished that year.About the only difference between the inside and outside ones is the added insulation and bigger shell on the outside ones.They are spray foamed and the intake air pre warmed by running next to the boiler through some tin ducts under the spray foam.If i could do it cheep i would add some more spray foam,mabey making it more efficient.

    I'm in my first season with an outdoor 150, its outside on a slab, no storage

    not sure about white tag

    I paid about $9000 delivered (but that was a low price, most sellers were around $11k+)

    I can easily see the benefits of storage with this (or any unit). Without storage its basically like any outside boiler,IMO. It idles, smokes, etc. I have well seasoned hardwood, my meter reads 20% or less, but the idling is what must hamper any non-storage unit. Depending on the temp, I get anywhere from 12-20hours out of one load. If I'm home I'll time, and size the loads to get some cleaner burns but thats not always possible.

    my current pet peeve is that I'm getting alot of ash being sucked (or blown) through the turbs and into my chimney. I've had to remove the cleanout cover from the tee so as to allow the ash to drop to the ground. Makes quite a mess. The factory thinks I'm getting "to much draft", not sure about that tho. Anybody have any thoughts on that...I'm all ears. Not looking forward to tearing it apart this spring to clean the insides. DSC_4270.JPG

    I monitor my draft, it is kept withing factory spec. I get some ash at the bottom of the T. I take out maybe an inch every couple of months.

    The Beauty of storage is extended burning season without making a mess of the boiler. I started burning October 10th and will most likely continue until April.

    how do you monitor the draft? and what is the factory spec for the draft. I get like an inch at the tee every few days!

    I agree about storage, seeing it in action without really shows that storage would be very nice to have.

    Factory spec is negative draft of

    -.02 minimum wc
    -.05 maximum wc

    Hi Mauler
    I used a longer cleanout on the bottom of my tee.
    I get about 2" per month,mabey a little more,my cleanout is about 12" long.My chimany is about 20' and i get quite a bit of ash on the snow around the chimany.

    thats interesting, so you added 1 ft to the bottom cleanout? with my current ash production that would probably fill up in 1-2 months. I thought about putting a metal barrell under the open cleanout but I dont want to leave the tee open. I'm thinking this will lead to further creosote in the chimney. Currently it is a major mess, occasionally the unit will burp out a load of ash (I'm guessing it gets clogged and the pressure builds to push it out), I happened to watch it happen a few weeks ago and it was surprising to watch.

    I'm thinking that all that ash getting into your pipe & cleanout means less ash in the boiler to clean out - which might be a good thing overall?

    I'm also further thinking about some kind of setup where you have an ash catching something-or-other on the ground under the cleanout (like a metal foundation coating bucket or maybe some 8" smoke pipe with a cap on one end), and you connect that to the bottom of your T there in a way that is easy to unconnect (metal flex duct that just slips over?). Then every week or two (or however long it takes to getting full) you just take that off & dump the ash somewhere & put it back in place.

    You might have a self-cleaning boiler on your hands & not know it. :)

    I had alot of ash going up the stack on my Wood Gun. I ended up installing a blast gate to the bottom of a tee on a 90 degree bend to remove the ash. Made the chore much easier. Google "Blast gate".

    I'm afraid that would get all gummed up with creasote

    anybody put a damper on their wood boiler chimney? that probably also would get gummed up and out of spec

    appreciate all the ideas guys

    You have creosote build-up on the bottom of your stack? I thought this was a gasser.

    Are those your pex supply/return lines running above ground in the black piping? Have you ever measure your loss in the lines? Seems like a double whammy for efficiency - boiler outside and lines running in the open. At least your wood is covered though!

    Hmmmm...you should not have creosote pooling in the chimney of a gasser. How seasoned is the wood? You should have two years on most hardwoods, sometimes longer for oak. Are you seasoning before you put it in your wood shed? It looks tight in there with out much airflow. This might be contributing to your wood not really being dry. Just my two cents though.

    no just ash, but I was thinking that could still plug up that blast gate

    no that was before install, those lines are 4-5 ft below grade. From what I measure I have almost zero loss along the 50' of ecoflex.

    1-2 years out in the sun and wind, then in the shed. My moisture meter shows 20% or less.

    sorry I misspoke, it isn't creosote in the chimney, just ash build up

    Good thing that was dry wood........we would have tied you to the cross. and torched it up. We is a bunch of dry wood fanatics...think the gun lobby is bad, take away our seasoned wood, that would be worse than the Boston Tea Party.
