I've picked up an older Eko 40 gasification wood boiler, an unused, 2024 production date, 1040 gallon, ASME certified (but I need to insulate) thermal reserve tank, an older 41 Gallon BoilerMate Indirect water heater, and am looking into expansion tanks so that I can start laying out my plans for installing this all.
I've been hearing/seeing that expansion tanks should be sized roughly 10% of the system volume, and understand that there are calculators out there for sizing them, but without knowing the delta temps at this point, nor exactly what volume will be with the lines running to the house from the detatched garage it will all be be housed in, I'm just going off of that "rule of thumb", which is telling me that I basically need a 150-200 gallon expansion tank, which is a hard find.
I have have some height in said garage (I believe it's almost 14' tall ceiling, and I do have a crawl space above it, although it's not an easy access), and see that mounting the expansion tank above it will lessen the size needed--is this correct? If so, by how much?
Is it also acceptable to run several smaller tanks in series-parallel?
Any other solutions to "skinning-the-cat" that I'm missing?
My plans are to hopefully batch-burn this boiler as opposed to letting it idle.
Thank you.
