    more info req.

    So far you have two out of the six pieces of information needed to size the tank.

    Max Temp = 180 deg f.
    Volume = 130 gal...(I gather from your email you are from Canada so is that US or Imp gallons?)
    What mix of glycol if any?
    What would be the coldest fluid temperture used to fill the system?
    What is the minimum fill pressure? (Typically the PRV fill setting)
    What is the relief valve setting? (From the boiler relief valve)

    Only when you have this information can the tank be sized correctly.

    If you let me know what part of Canada you are from, I'll provide several names for you to contact.
