I have this in the fine tuning Biomass thread but figured it may get a little more attention out here in it's own thread. Biomass users what's the life expectancy on these things? I've been planning to work on a setup with a Vedolux v37 setup probably in my basement with 3 210-250 gallon tanks. I had a used Biomass 80 pop up online near me though. Would you touch one 9 years old on the used market? I can get it with 1000 gallons of storage (2x 500 gallon repurposed propane tanks) that's been in use since 2010. Outside looks good; inside looks like it has a fair amount of creosote on the upper chamber but maybe that's normal for them? Said it's been used about 2 months per year for heating a greenhouse so I'm sure it was run hard during that time period. It would allow me to build a boiler shed next to the house for all the equipment instead of taking it into the basement through a 32" doorway. (up 3 steps to the house, through 2 rooms of hardwood floors and down a flight of stairs, 3 doorways and 2 degree turns involved). It may be a much more economical way to get going then in 5-7 years depending on how long those things should last if I want to go to a different boiler with more bells and whistles I could. I'm only 34 and plan on living here for a very long time so I've got time to get the life out of equipment. I honestly think I would prefer it in my basement for convenience; but it would take up a fair amount of real estate for wood, boiler, storage, etc. There's pro's and con's to both locations for the setup. That's a whole other rabbit hole though, the first step what do you all think of the boiler from a few initial pictures?
