Ok, so I have been planning this build for the 10 years I've lived in my house since built. Finally getting around to it! Background: home is roughly 2500sqf with radiant tubes in basement floor (planned on an owb from the beginning). Will be adding a HX in the furnace and a side arm on my electric water heater for DHW. I will also be heating a 34x48 shop to 45-50 degrees (with HX) unless I'm out there, then to comfortable temp (65° couple times a week, a few hours at a time). The boiler will be roughly 100' from the house and 10' from the shop.
Finally, this build will be a tank in tank design. I am using two propane tanks that are 30" and 41" in diameter. The plan is to use forced draft, with a ranco aquastat, and two appropriately sized pumps, one to the house and the other to the shop. I think I have decided on roughly 320 gallons for my water volume in the boiler. Please vote in the poll and comment if you have a good reason for me to change my mind on water capacity...
And yes, I know that it didn't happen without a pic, so here is what I'm working with:
