If I was to go with a batch box how big of a box how big of a opening between the riser and the box I and any ideas on a door

Thanks for the links
Think I’m going to cap with the fiber board and put a layer of fire brick over that how big of a bell can I go with if I do a 8 inch system

Thanks for reply

My first thought was a fire brick cap but thought the steel plate would help give a faster radiant heat then the masonry mass would take over after heat up and after fire is out
But if I can just cap it with fire brick and still have fairly fast heat I’m good with that
This is going in a basement right in front of a existing fire place in a man cave I’m going tie this right in to the brick face of the fire place and hook in to existing chimney
Leaning towards j tube but just really haven’t seen much info on the batch style
I’m not familiar with the insulation board
Thanks for replying any info and ideas is greatly appreciated

I’m a bricklayer so want to use as much masonry in my heater build as I can
In stead of a 55 gallon barrel has any one used a block and brick box around the heat riser with a 1/4 or 1/2 inch plate of steal cap above the riser
Then I can channel the hot gasses from there to a masonry mass and or just use it as my mass to store heat
