year around
summer time i only put in a few pieces during the night just to carry over to the next morning. from 6am to 11pm only garbage gets burned..., while i'm at work, mom does yard clean up. keeps the yard clean, and it's MORE then plenty to keep the hot water up to temp.
during the cooler/colder winter months, heating 2 houses, both garages, 2 DHW, 1 shop , hot tub, 2 clothes dryers,
during the summer, only the clothes dryers and DHW. maybe hot tub if i blow out my back or something....
summer days, burn pine needles, leaves, shrubbery, limb clippings, bush clippings, etc etc.
summer nights, few pieces to carry over to next day. mostly punky dry pine (deadfall from years ago, the stuff that falls apart into 4 different chunks as you try and pick it up, saving the good stuff for when i really need it). Really has cleaned up the ground of the woods, much easier walking. literally must have 100 trails in my 80 acres to get around with my tiny tractor and trailer....
i wince at the thought of burning the good wood to keep the water hot...
btw, burner is set @ 196F
