New member here looking for help figuring out which boiler may be best suited for my useage. I am currently using an oil fired water heater supplying the in-floor heating. This system would remain in place and a wood fired boiler would be plumbed into it. Initially at least I would not be using any storage. One of my first concerns is wood quality. There is a lot of wood available in this area but it is of two main types: driftwood and scrap (meaning wooden pallets for the most part). Which boilers would have the least problems dealing with this? Thank you.
