Scott, Max BTU output is 120k for the g100 correct? That means that if you heated a large heat store, say 500-1000 gallons for 4 hours wideopen at 120k per hour you would store 480k btus or somewhere about that? Home that requires 50k btu per hour would last 10 hours + on that heat store? 50k btu is pretty high for a heat load correct?

Gassers need a good coal bed to burn cleanly. The first few hours of a new fire you do not get a good burn. I'm not sure large storage with a burn once a day will be the answer.

[hondaracer2oo4]

We all agree that the amount of btus needed is the same regardless correct? If the burner needs to run 6 full hours to store enough btu to last 24 hours then you run one full firebox then a half a firebox. This keeps you from needing to load every 8 hours.

Yes the fire boxes are small to make them cleaner to pass the darn epa test, was speaking with a guy about it this morning

In regard to batch burning, it wouldn't do much good to add more storage to this unit,  it's not possible for it to hold any more wood so if you did have storage it might rub wide open for 4 hours, but then you need to reload it so what does that accomplish?   Nothing in my opinion

Not to derail the thread (much) but if a person was building their own and damn the emissions the fire box could be larger and not affect the gasification process?

I don't mind twelve hour burn times, the one I built will run much longer if you fill it, but seems more efficient if I load for 12 hours at a time. Load it up at night, then check in the AM and adjust the amount i add. If it's warmer out I may leave it go to burn the coals down and get ahead of the ashes.

 I guess you could discuss that with the EPA after the regs pass.

I guess you could discuss that with the EPA after the regs pass. 

Maybe I misunderstood what I heard somewhere else or it was just false, but I thought homebuilt were exempt.

[yoderheating]

 I have no idea, I didn't see that when I read it but then again I wasn't looking at it. Legal or not I feel certain there will be plenty of homemade ones out there after people can't buy what they want next year.

Honda racer,  my numbers were just in theory

With a stove that gets these kinds of numbers and emissions down to .07 vs most gassers at .32
There isn't a lot of room for improvement during the down time in my opinions.

Look at some garnish customers, I know a few, even with 1500 - 2000 gallons of storage this winter a lot of them are firing twice per day..  I donno about you but I don't like building a new fire and going through the kindling process.  I'd rather load and forget it

I just don't see where u think all the extra btu will come from,  let's look at it like this for example.

5 cubic feet of wood, let's say it weighs 40 pounds

Moisture content is 20%

That means 344K btu, instantly reduced to 275k btu by moisture content

Now if the furnace can capture 80% of what's left.   

We are down to 220k btu of actual usable heat

If our heat load is 30 btu per hour,  u got about 7 hours worth

If you could put those 7 hours in a tank u r still out of wood. 

Now it may hold more than 40 pounds depending on the type and how it's cut, but those numbers were just rough ideas

I know when I ran the XT100 the firebox was very small

Scott7m, what kind of cost on the new G units

[yoderheating]

G100-$7,500 G200-$9,500

[mtoll]

In 2015 do I under stand you will only be able to buy G models or can you buy the 350,000 plus btu models

[Scott7m]

The latest and most credible info I've seen says there will no longer be a btu loophole as there is now in certain states

[mtoll]

Scott7m Thats interesting

[yoderheating]

 The info I've see will not allow large furnaces of any kind. Unless its changed there is a cap that large gassifiers will not even be able to meet. Scott, is that the way you read it?
