I am looking for advice on how to best use my buffer tank to get the most out of it while using the least amount of wood. It is in my basement with my Wood Gun. Any heat that radiates off of it goes into the basement, and eventually up the stairs into the house. Now that the temperatures are getting colder I am loading the boiler twice a day and letting it cycle on and off. The Wood Gun is running smooth. I am very happy with how the system is working. When loading twice a day I know that the water in the tank is not being drawn out of it to heat the zones with, or at least not much of it. I guess the only time it is is when the boiler runs out of wood, which has happened a few times, and is not hot enough. Then the tank does take over. Works great. Do you know what I mean? A lot of the time I am sending that heat from the boiler to the tank and then not using it. Am I therefor using more wood? The tank will only put out so much heat due to it's size, so I can not do just one or two burns a day unless I changed a few things. Just thinking out loud here: I suppose if I added a low temp shut down for the fan I could put less wood in (say, enough for 6-7 hours of burning), let it burn until it ran out, and then the tank would take over to get the other 2-3 hours of heating I need. But, then it would seem like I would use just as much wood to heat the boiler and tank all the way back up to 175. ? I guess I am not loosing any of the heat since it is going into my house. With these temps the last few days I am loading the boiler at 07:30 am and 07:30 PM. Boiler is out of wood on both occasions, but still 150 degrees. Thanks in advance for any suggestions.
