Would it be possible to use multiple reels of pex to build something that would substitute for a storage tank? The whole assembly would be insulated. I have no idea how/if it'd work.
Wad'ya think?

Well, if you used 1" pex let's see how the numbers work out:
1" inside diameter is about 9.4 cubic inches of water per foot of pipe.
At 231 cubic inches per gallon, that means it would take about 25' of pipe to hold a gallon.
That works out to 25,000' to hold 1000 gallons of storage.
I'm thinking that would be one whacking big pile of pex! On the other hand, that would be almost enough to heat my house from your boiler, so maybe it's a good idea after all
......You could maybe improve on the coils of pex by wrapping them around something that could absorb/hold heat......
According to the Viega pressure drop table, it's about 0.016 psi pressure drop per foot for 1/2 inch pex at 1 gpm. So figure 400 psi for 1 gpm, about 800 psi for 1.5 gpm. Of course I'm sure there'd be two or more parallel circuits, so it wouldn't be anywhere near that bad!Just out of curiosity,
What would the pressure loss be on 25,000 feet of pex?
