Boiler heating system expansion tank.

[NCPABill]

I bought a gasifier indoor wood boiler, with which I will also have 500 gallons of hot water storage (propane tank). I need to add expansion ability to my system for this tank. Would it cause any problem to install an expansion tank on a riser from a hot water storage tank? I will be installing my tank and one end will reside under my stairs. I’d like to install an expansion tank up under the steps, but I won’t have any lines passing through that area. Could I install a riser off of the top of the tank, 90 to horizontal, and tee down into the top of the tank?

What do you all think?

Thanks for your time,

Bill

Just kidding o nthe quality of the sketch, but it might help to see what I'm trying to do.

Thanks again for your help.

I see no problem with your idea. I am assuming that your system is pressurized, hence the expansion tank. I have a similar set up with a Classic, but it is not pressurized so I have no need for the expansion take.

Here's exactly what you need, they also have a sizing chart to help you determine the right capacity tank to use. Also, an air scoop/vent is a critical part of any hydronic system
