I've learned a tremendous amount about the different type of wood boilers the past couple days. Even picked up on some of the abbreviations. I'm new here to the community and tried posting last nite but apparently it didnt go through. I know I need to do a heat loss calc. Here's what I know. I have a two level decently insulated farm house. Its heated by a fuel oil perfect temp boiler with wall registers. This past year I have burned 2000 gallons of fuel. I don't use number two fuel oil but rather farm diesel and treatment. Cheapens it a little, but not much. Staring at 4.00 fuel scares me knowing it will cost 8k to heat the home. I am not afraid of the big up front investment of a wood boiler. I know it will pay me back. I have an endless supply of wood and tools to gather it. However I'm not totally sure what will fit me best. I know I don't want an Outdoor woodburner. I've combed these pages looking for ideas. I think a storage tank is a must for my situation. (only able to stock fire morning and evening.) I prefer something simple to maintain and operate. Of all the ones I have looked at, the Garn seems to impress me. Its water capacity, simplicity and durable design makes it very appealing. The Eko, Tarm, Greenwood and Switzers sound like equally nice machines. Currently I only heat the house. However, I have an unattached 2 car garage that I would like to heat and a section of my mortan machine building to heat. Thats probably 5k-6k feet. I would probably be here when I am heating all three. So the question would be. What system best accodomates 1) Stocking a fire twice a day to heat my home 2) Stocking the fire 5-6 times a day to heat house, barn and garage. I also plan to put the boiler in the garage. Appreciate everyones input!
