If the aquastat on the storage tank is set at a higher temp than the aquastat on the boiler itself, the pump supplying the storage tank won't shut off. Also, 150 deg for domestic hot water is too hot - might cause scalding.

: sorry, I meant aquastat on the hot water storage tank. It never seems to turn off the circulator bringing in water from the boiler. It's set at 150ish, and I'm not sure if that's a good temperature to set that at in the storage tank? Any help?
