    Its a funny thing. I was looking at a few OWB's and comparing the lack of creosote in my chimney ( 165 Shaver ) and the black mess coming out of others. And the higher the chimney the more the mess.

    I'd be real sure I'd need a higher chimney before I'd mess with mine.. the true " ash pan is another story.. "

    I used your idea for Fletchers steam fix, I put a piece of 1" pex 6" long with the curved end up on the overflow tube, secured with a hose clamp, filled with water half way out, and does'nt overflow the DHW tank, now no more steam!!! But now if I have to add chemicals I guess I'll have to take it off a couple days before so it can steam and water level can go down. Better than resealing the DHW cover every time. Great ideas guys, keep them coming, Thanks!!!!!!!!!!!!!!!

    Ordered the solenoid yesterday, should be here mid week. On yours, when everything is up to temp and draft cover is closed do you still have smoke coming out the stack???? I closed mine all the way and waited 5-10 minutes and still had smoke coming out the stack, I thought that would kill all smoke if no air was getting to it??

    The only way you'll kill ALL smoke is if the fire goes completely out.

    After 10-15 minutes, you should just see gentle smoldering smoke coming from the stack. The fire is still getting some air via the stack (small downdraft).

    Yup, The smoke will just gently roll out of the chimney when closed. When the blower is running, the smoke is pushed out with force.

    Simple idea, it's even in the manual, but I didn't start implementing it until today. If your blower is on when you go to load tour boiler, open the ash door before pulling the coals forward over the grate. I was going to add a switch to the front to shut off the blower, but figured I'd end up forgetting to turn it back on after loading. Works very well so far.

    Here's a pic after raking the coals forward with the blower on and the ash door shut. it's a crappy phone camera, but the flame was mostly blue.

    You could use a 3-way switch,In one position the blowers on,in the other a loading/reminding light is on...

    Fletch, I see you are in Ct so I'm guessing you're burning anthracite coal ? Nut or egg ? Its around $ 175 a ton down this way..

    Miscommunication on my part, the pic is of my wood coal bed. I'm planning to try burning coal though at some point this winter. If it works out well, I may end up building an area to contain the coal and get a dump truck load. I know anthracite is available and I think the price is about the same as yours. Do you burn coal? If so how does it compare to wood, usage wise. Does a ton = a cord of hardwood?

    David78, your description on water flow and heat transfer sounds correct to me. But what you describe as top or bottom nipples is relative to the air flow direction of the blower. What I mean here is some forced air systems have a blower that blows in the "up" direction and some blow "down". If you want to maximize heat transfer then you want to flow the water and air through your heat exchanger in opposite directions. In other words "Counter Flow". This method introduces the hottest water to the air exiting the exchanger flowing to your ductwork and vents. On the flip side the slightly cooler water exiting the exchanger is preheating the air as it just enters the exchanger. I hope that explanation helps. On exchangers this size the direction does not really matter all that much in heat transfer. But to those of us wanting to tranfer all they can then counter flow maximizes heat transfer.

    The 3-way is the best use. I have one side of the switch powering the yard light on the front of the the boiler. The other side of the switch powers the blower. Way to go Beerman. I have also wired a normally open thermostat in series with my aqua stat. That way if the water temp gets below what I set, 140 in this case, the blower goes off. Works great if I sleep in or go out of town. That way the blower is not blowing sub zero air in the burn chamber. It was a $20 dollar unit. If anyone is interested I can post the wire diagram.

    fletcher0780, Here are the mods I have made to date on my Shaver 165. I installed the Ranco programmable temp controller in a copper tube drywell to help take the jacket water temperature swings out and put an on/off switch mounted on the side of the unit for the blower while loading wood. The only other thing is I have played around with is a blower door solenoid similar to yours, but I have yet to perfect it. I think I will try your fix on the fan door. That is it for now. I will keep you updated on any future changes I make.

    My blower door seems to be working well, I'll know for sure when I get home today, as it is quite warm out and I filled the firebox this morning. If all goes well I'll have no boiling issues. I have my Ranco set to blower off at 165, blower on at 155. Still looking for ideas on insulating the firebox door.

    Have you done that? I thought it would melt.

    Melt at 185 degrees? I would think it would be just fine.

    I'm not talking about insulating the water jacket, I'm talking about the firebox door in between the two panels, which is exposed to far more heat than 185.

    I just put a solenoid on my fan and made a damper out of the door. Thanks Fletcher! I also had to use a string to keep the door from over opening...I used a solenoid that we had laying around at work so this only cost me $6.00 for misc. parts and my time spent in the wind and snow this afternoon doing the mod. It all seems to work good right now...hoping this will reduce fan run times. Should know after a week or so of using.

    Thanks again!

    I've got some people working on the door insulation problem and will let you guys know what comes of it.
