I'm planning on installing boiler and storage in boiler room attached to garage. What do you think about a tank like this for storage?

It is a thermoplastic tank, likely polyethylene.why though?
I don't know if they will hold pressure, I just ran across them this AM. Odds are that they will have a big fill hole in them that should have a cap with an o ring. Pressure shouldn't be an issue. What kind of pressure are the boilers running?
a common misconception. actually most average homes only need 4-5 lbs. and that is just enough to help the pump.Heh. No.
I don't know what exactly the ASME boiler code states for design guidelines, but a typical design pressure is 4x the relief pressure.
Most systems run 15-20 psi, my relief valve is 30 psi, and that tank isn't rated for any pressure.
If it somehow is pressure rated it will have a nameplate and you can see what it was rated and tested at.

But I dont think anyone here is going to recommend a plastic tank of that sort for hot water storage, regardless of if its pressurized or open.
