I have been slowly researching alternative heating methods. I have a older, 1932 home, that I insulated last year. That cut our heating bill way down. I would still like more and am bouncing between replacing the pre EPA insert with a new gasifier, or getting a outdoor gasifier. What do you do when the power goes out? How do you keep the water pumping through the system to keep the house warm? Is there a model that can take the some of the gas from the burning process, and divert it to run the generator? I have seen hoe made units that are dedicated to running engines. Is something like that even possible?
