Is that true at extremely high temperatures? I would think that high temperatures are harder to store.

Firebrick is century old technology, used for regenerative heating of air in steel making (outgoing gas heated firebrick, then air was drawn through that on the next pass, with two banks of firebrick being used in alternation).
- LinuxBender 6y agoI learned something new today. I was going to use kiln-fired bricks for a rocket mass heater, but I had never heard of silicon carbide bricks. They cost a lot more $10 vs $3 but for a small project, those are perfect. Thankyou!
- crote 6y agoA problem is that insulators work better with a lower temperature gradient, so hotter storage will lose more energy per second.
- pfdietz 6y agoThe studies I have seen show minor energy loss (a few percent a day) although this is a function of scale.
