Hello to Fellow Wood Burners. I am actually a dealer/hydronic person for an unmentioned " Not Econoburn" brand of "So Called" wood gasification units. I have installed or been involved in dozens of OWB and Wood Boiler Applications with good success and satisfaction. I am currently (almost formerly) involved with a tankless line of wood boilers. Currently on 2 difficult cases with many problems, the main ones being short burn times and coked up heat exchangers. Both clients burning good quality, seasoned hardwood. Two totally different houses, 1 forced air, 1 radiant in a slab with DHW from 2 50 gallon Triangle Tube Smart Tanks in series. Both cases have short burn times and use a ton of wood. I am no genius but have to qualify myself as quite experienced in hydronics and water flow. My client is an engineer that works with million dollar hvac systems so together we got at least 1/2 a brain more then most of the manufacturers we have dealt with. Every direction I go in leads me to believe that the best bet for successfully heating with wood gassifcation is burning a long hot fire and storing the heat in as much water as you can afford ie. tank storage. The unit I have been dealing with has a huge concrete refractory that is supposed to store the excess heat. I don't think so ! The unit I have been dealing with is supposed to burn cleanly and not creosote. I don't think so ! The unit I have been dealing with is supposed to support re-combustion for 48 hours...No, It Does NOT. It rarely holds a fire over 6 hours...and is very hungry. I am currently looking at taking on Econoburn and adding storage as I have been to the factory and I like what I see. This doesn't mean there won't be bugs... and I have yet to make up my mind. I will not however quit. Oil Costs TOO Much ! Wise Men Still Seek Him.
