Hi fellow members. This is my first post. I joined this community to share my boiler project with everyone in hopes maybe others can learn and hopefully I can learn from others. Last summer I started building my boiler because I was tired of the inefficiency of my insert in my fireplace. Plus the mess of bringing the wood inside and the ashes.... I'm sure you all know how it is. I started the research found our about gasification and decided to have an adventure. Anyways I've got the firebox finished and working great, I believe at least(there's no smoke at least). I have pictures of the build if any wants to see them. I will post a few links to videos of it running. First run after making the airflow to the upper chamber. Second run start-up. Second run after full gasification started. Oh yeah, the upper chamber is an old hot water heater. Lower chamber is three freon bottles welded together. The outer water jacket is a 300 gallon disel fuel tank. I know none of this is conducive to rust inhibition dut this is just a test. My next booiler will be stainless or aluminum. Any suggestions comments or ideas would be great.
