What sort of heater? A little corner-of-the-room thing, or a "whole house" contraption?

Cost? I guess sheet steel protected by brick will be cheaper than thicker cast iron.
The manufacturers websites will give the maximum output heat; convection plus radiant so you need to find one similarly sized of each type.
Fitting a boiler instead of the firebrick has a big impact on the heat to the room and may lead to poor combustion due to low hearth temperatures.

Not a lot if the wood is near bone dry (say 12%mc wwb) for damper wood the firebricks keep up the temperature to stop the flames being quenched by a cool surface before they have finished burning.
