No, CS you can't use a boiler pressure relief valve on a water storage tank - not from a steam boiler nor from a hot water or hydronic boiler. The operating pressure ranges are different, and the water temperature sensor on the steam or hot water boiler TPR valve would of course prevent mounting it directly onto a water pipe.
