I heat with a wood boiler and have 700 gallons of water storage. the temp rise is from room temp 65F to 210F deg. How much expansion should there be. ( 2 tanks 12" X 48") is that enough. The boiler and the storage is under pressure at 12-15 PSI. Any help would do. Is there a site or on this one that has a calculator for this issue.
