Got the majority of the money rounded up, and am starting to look seriously at purchasing a boiler. I've got about $5,500 to spend on the boiler max, and am looking at an EKO 40, Biomass 40, and an Attack dpx45 profi if I go the new route. Also scanning the horizons for a reasonably priced used boiler in the 40-60kw range, but not holding my breath at this point. I have 2,000 gallons of pressurized storage gathered, and am putting all this in an out building or a shipping container, or a combination of the two and an existing pole barn that I already have. Whatever works when I have all the boiler in hand. Lines and general setup are already in place from my previous Central boiler. What I am wanting to know is peoples experiences and opinions on the EKO, Biomass, and Attack boilers, and pros and cons of the different set ups. Any leads on good used boilers would also be appreciated. Thanks.
