    Sure. I won't be home until late tonight but I can let you know Friday morning.

    While we're talking about boiler temperatures, there's about a 10-degree difference between the aquastat and the gauge on the boiler. I have the aquastat set to kick the boiler off at 180 which gives me 170 at the gauge. Not sure what to believe but I'll er on the side of caution and believe the gauge.

    It shouldn't be that hard. All the cycle timer does is parallel the purge circuit. The lower water temp basically parallels the overtemp, but in the opposite direction. When the low temp limit is satisfied it allows power through.

    I am interested to hear about your cycle time experiences. I will be wiring one into mine once it is up and running. What was the AHS suggestion for timer settings? Why didn't that work? Did the fire not restart?

    Wow. That Wood Gun is going to be doing some idleing. Perfect application for some thermal storage of water. Do you think you will add storage in the future? You could have a fire once every two days a lot of the year and heat your house.

    I had a fear this thing would heat my basement. That's why I put in an electric water heater for summer.

    No worries about the cycle timer boiling you over. The overtemp protection is #1 in the circuit. Nothing but a failed overtemp aquastat will make this force itself to boil.

    Sounds like a nice problem to have.

    It was set at the factory to fire for 12 minutes every four hours. At that setting with nothing calling for heat the fire would go out. Yesterday I changed it to fire for 12 minutes every two hours. We'll see how that works.

    I don't have any plans to, but I'll keep an eye out for old propane tanks and water tanks. With the way these WGs bleed heat off I'd have to isolate them from the boiler after they're up to temperature. I like the simple layout I have now...I'll be slow to add more whistles and bells to it.

    If there's one thing I like to do, it's cut and split firewood. My wife thinks I have a problem. Go to the beach, go for a hike, go to the city, go to the amusement park...I really want none of it. Put me in the woods with my tractor and a chainsaw or behind the barn with a maul in my hand and I'm a happy boy. I have all the woods and wood that I can use already and on top of that we had a wicked storm blow through here on June 22nd and knock over probably 5-years worth of firewood (and timber for lumber) on my property alone. The amount of wood I burn isn't really an issue for me. 5 cord a year or 8, I don't really care.

    If I were smart I'd sell the new coal boiler and run 250 of insulated pex out to the barn and heat it with the Woodgun. I'm going to pipe underground power, water, compressed air and phone out there next year anyway. I'm still considering that..... The WG would run more often and more efficient and I wouldn't have two different boilers to take care of. Food for thought.

    That is a long ways. I wonder what you would need to pump that far and back? And other considerations you would have to make.

    thanks. Funny thing is I was just reminded that I allready knew that and had posted it in an old thread last year. So I looked it up and I'm good to go.

    As far as Hawken energy, i bought 2 global hydronics thru them and both leaked, after patching and leaking and patching and leaking and finally getting a lawyer we got them replaced at considerable cost to us and 2 years without the boilers now one is leaking again and it has been patched several times. total junk.

    Thanks for the link! Probably worth the drive.
    BTW, here's a picture of the coal I have on-hand right now. :)

    Hi Woodsrover I am reading up about the Wood gun boiler to learn more about them and Im curious about how you have yours ducted. I see in the first picture two horizontal stove pipe/ducts running towards the wall, the top being your smoke hood exhaust and the lower one Im thinking is the air intake. What Im curious is where they go. Does the hood exhaust go out the wall or into the chimmny pipe? And the air intake does it just stub off inside the room or vent to the outside?

    So Im curious how its been running it, do you get a lot of smoke into the room even with the exhaust hood?

    Thanks

    ~ Phil

    Hi Phil,

    The smoke hood pipe goes just goes through the wall to a dryer vent with a flap. The intake air is the same thing but with a screen to keep the critters out instead of a flap.

    It's been running great. We shut it down the first week or two of May but was running up until then without a hitch. And no, with the smoke hood running I get little if any smoke in the room. It does a pretty good job.

    Hi thanks for the info, I am very intrigued by the wood gun, a possibility for us as we do not have the space for storage or the desire for a complicated system. So did you have a conventional or outdoor boiler and did you see any reduction in the amount of wood you burn going to the Wood Gun?

    Thanks ~ Phil

    Heated with a VC Vigilant before this boiler. Used 5-6 cord a year. Only one season under my belt with this WG now but I burned probably 4-5 cord, heated hot water and burned until April.

    If
    if you can install a wood boiler then you can install a wood boiler with storage. Space should be your only limiting factor.

    Yes space is the issue, no room in the basement and I don't want to do something outside nor does my wife. I fully understand that no matter what I install without storage it will not be as efficient. I am trying to find a gassifier that can perform ok without storage, run with minimal creosote buildup is my main concern, second is to reduce the amount of wood we burn, not looking for cutting it in half but dropping it by 20-30% would be nice. The other thing is I want to cut my wood at 2ft lengths, its easier, less pieces, less handling.
