Ming,
I hope your stack is not as tall as Matty's!

Are you on a budget plan?

I guess that wouldnt be useful then. Assuming yours don't have an airleak too. 
I see 2 to 4 degrees when I go load my OWB sometimes, but thats not often and I don't really keep track of it.

Are you getting some overshoot of your high setpoint? In other words, if you have it set at 180, have you ever noticed if the water temp continues to increase above this point? If so, how much?
If it is a lot, im just guessing here, by 5 to 8 degrees or more, this might indicate that you have an air leak.
I guess this could vary by type of OWB perhaps.
Any thoughts on that RSI? Can overshoot indicate this sort of problem?

Oh, how big were those trash cans? I am imagining a regular size trash can and that would be a lot of ash! I usually get about a 5 gallon bucket full per week.

The creosote can have an insulating effect and potentially have some effect on thermal transfer.
After cleaning it out, I would try running a higher setpoint for you water temp, try 180 if you haven't already. Are you burning some green wood perhaps?
I hope you get her tuned up!

Can you pressurize a system made of stainless steel?

Theoretically, if you had a circulation pump with variable flow rate up to 50gpm, would this element of the OWB system have more relevance to a PID controller than the draft element?
I think PID controllers are useful, assuming it can auto-tune, in controlling certain elements. FLCs and MPCs are superior in steam boiler applications but they control flow.
To be convincing, I think whatever data you have collected would need to demonstrate the following:
1. Safety
2. Improved fuel efficiency
3. Cost effective
4. A picture of that firebox after 3 or 4 days
It appears you have already printed circuit boards. I wouldn't think that you would have proceeded to that stage without having collected data. What data do you have at this point?
This is a very interesting thread.

I visit her everyday.
She opens up without a fuss.
I fill her up.
She likes to smoke after I'm done.
She never complains.
Never has a headache.
Can we marry these things!

HeatMaster / Re: Temp. On the OWB
« on: January 24, 2012, 04:59:23 PM »
I was wondering the other day if I might be able to get a lower differential between supply/return temps if I changed my OWB diff from 10 to 5. Any idea? I burn hardwood mixed with a couple pieces of poplar (trying to get rid of it!)
I'll say too that I started running my secondary draft wide open, I think it burns more efficiently with it open. I'll just clean the pipe out every so often unless you guys advise against that.

Are the bench tests available? I want to see how it stabilizes water temps without having influence on the pumps flow rate under full loads.
