Has anyone ever setup a couple hot water tanks for storage of just DHW? I currently have an indirect and I was thinking about putting a couple storage only tanks inline with it and maybe just putting my recurc line back to the 1st one and letting the indirect heat the whole lot of them and then in the summer burning just to keep the DHW Hot. dont have a lot of space in my furnace room but I could probably fit a couple 120gal tanks in there.
