This is a 2 year update to answer your question about my stove. My goal is to simply heating the floor in your shop. This is my home built wood stove / boiler for in floor heat in my shop. It has been in use for a couple years and it produces amazing heat. Ask me anything and I’ll try and answer or possibly make a video to explain it better. This can be simple, cheap and done on a budget. That said you will have to put in the work and get after it however in the end it is worth every second you put into it.
