Hopefully he'll be able to take a look at his heat exchanger and figure out why he is only extracting 5 degrees off the water when it goes through the hx.

Sorry guys for not replying sooner. I appreciate all of the comments and I will try to answer the questions.

I didn't think the numbers were correct but I figured the temp difference was what was needed. What should be the difference between the out and in at the owb?  We just had a cold front come through. I've been burning seasoned locust and it has improved my burn times some, but I'm still not getting more than 10 hours when the temperature is below 35 degrees.

I am going to try to follow Hondas recommendation and try to get a more accurate reading.  It would be difficult to take the hx out so I would rather not try that.

How would I go about checking for the air bubble? 

Regarding the filters...I change those about every month.

I have their thermopex buried about 20" deep. The dirt has settled so water lays in the ditch at times (new construction so no grass seed planted there yet).

Linda...The 2000 ft does not include the basement but I would like to add that in the future only turning the unit on when I'm down there.

If I sell, what do used (1 year old) units usually sell for?  Brand new before taxes is $5000.

I don't think I would sell.

Your firebox is much larger than mine, you should (On Paper) be able to transfer heat faster than mine.

Sounds like you may start looking at the water laying in your ditch.

Yea the problem isn't the stove at all. Your numbers are telling us that you have some issues there. Please retry your readings to make sure that they are accurate. You should not be losing that amount of heat from the boiler to the house and from the house back to the boiler. You also need to extract more than 5 degrees through the heat exchanger. Something may be wrong there such as an air bubble. If you could find some way to get access to the hx(not pull it out but  atleast be able to either put your hand on it or shoot the IR sensor towards it to make sure that you have heat all the way around it. What are your temps coming out of your heat registers in the house? You said the fan runs all of the time. That is because you are extracting so little heat from the piping that you likely only have mild temps coming from the registers. I get around 135-150 coming from my registers.
