need some input on my shop heat

Hello, I am in the process of connecting a zone on my EFM 520 boiler for my shop. I have a brand new Reznor 23/33 unit heater which I know is not big enough to heat my 24x32 with 10ft ceiling shop, but my question is can I run my heat through the Reznor first and then hit a large cast iron radiator and still get good heat from the radiator. I appreciate any input.

    Which reznor?

    How big is the boiler?

    What else is connected to the boiler?

    Have you done a heat loss?

    How big is the radiator?

    Is there a reason to pipe in series?
