Firebrick

I understand that firebrick are used to line wood stove. Has anyone use it in their pellet stove? Good idea or not?

Mine came with firebrick.

Mine too, 3 across the back but I have wondered why you couldn't put them on the sides to retain heat.

Mine has firebrick as well

Might have to wait 2 hours for it to shutdown to clean if you did that.

My Englander 25-PDVC didn't come with it. I was told that I should use it to keep the heat in. I see how it would also take longer to shut down.

I could also see that if your stove wasn't designed for it, how firebrick could be detrimental

I see no advantage to firebrick in a pellet stove. The fire is contained in the pot. A woodstove uses the firebrick to protect the metal sides from direct contact with the flames, yes?

I've only ever seen pellet stoves with ornamental bricks, not true heat-retaining fire bricks like in a wood stove. The biggest difference between a wood stove and pellet stove is that in a pellet stove you do not want to "retain" heat." The objectve is to transition the heat from the inside of the stove into the living space of your house without shooting too much of the heat out the vent pipe. True firebrick, I would assume, would be counter productive to the cause. Am I off course here?

The 3 in mine are true fire brick, I would assume to keep heat away from the back of the stove

Same here.

I replaced the fiber brick in my stove this summer. Have since thought about making a mold and pouring a fireback out of castable firebrick mix - cheap and readily available. Might work. The main thing with my stove seems to be keeping the back and the internals from overheating. Castable firebrick mix has a high ratio of insulating contents...
