floor bricks
should the floor firebricks be layed flat or on the side? what is the difference?

Re: floor bricks
A 2.25" brick layed flat will take less time to heat up to a given temperature while a 4.5" thick brick set on end will take longer to heat up but yield a higher volume of stored heat
up over a longer period of time. How deep you design your floor will affect the amount of wood you must buy and the time it takes to heat up your oven to your prescribed operating temperature.

Re: floor bricks
Is it twice as much to heat up bricks laid on their side: time- or wood-wise?

Re: floor bricks
I don't know if there is data to support this. Besides, fully saturating a firebrick is different than surface-heating. You would need a thermocouple embedded in the underside of both styles of floor and make a set of general assumptions regarding brick alumina content, wood type and size of fire, ambient temp, etc to get that comparative data. As in all things, your mileage may vary.
