I recently purchased two used 1000 gallon propane tanks. I plan on purchasing a wood boiler (probably 35kW or 40kW) and installing it along with storage in my workshop that will be built next year. The wood boiler and storage will be integrated with my existing oil boiler (in the house) as a backup and will be able to supply heat to both buildings. My design loss for the shop and house combined is around 55000 BTU/hr. I know that I really only need to use one of the 1000 gallon tanks for storage, but I'm wondering what people's thoughts are on having 2000 gallons of storage for the increased flexibility it would provide. Keeping the second tank would probably cost me around $1000 including the additional insulation and piping.
My other question relates to the placement of the tank(s). The workshop will have a basement. The tanks could either be horizontal in the basement of the shop, in which case they wouldn't take up any floor space that I care about, or they could be placed vertically, where they would take up a bit of main floor space in the corner of the shop. If I only used one of the two tanks, I think that I would be more inclined to have the tank vertical. The boiler will go on the main floor of the shop. How much better would it be to have the tank(s) oriented vertically?
