Fin tube radiators respond quickly with heat, but cool off rapidly once the water flow stops. Cast iron radiators are the opposite. They take awhile to heat up when the t-stat is calling for heat, but once they are hot, they stay hot for a good period after the water stops flowing. Perhaps you just are not used to the new characteristics, and you probably have way more BTUs of radiation than you used to have.
