Thermal Storage Battery Oven -

Solar/Rocket Stove Oven - Thermal Storage Battery - Solid State

Oven = Insulation + Thermal Storage + Heat Source + Cooking Surface

Insulation = Roockwool
Thermal Storage = Metal Box filled with sand/brick/cement with insulating legs+sidding
Heat Source = 485F/250C silicone insulated wires embedded in the sand connected to solar panels
Cooking Surface = Top of Metal Box, temp of 260F-305F/130C-150C when the rookwool insulation is removed
Optional Cooking Surface = Front Loading Cavity in Metal Box/Sand that can be closed and used an oven.

Oven = H x L x W = 48" x 60" x 48"
Insulation = 12inches(R-50) on all six sides of Thermal Storage
Thermal Storage =H*L*W =24"x36"x24" =12ft3/.34m3 (1248lbs) (.3398m3 * .58kW/C/m3 * 120C = 22kW)
Heat Source = Daily Heat Loss = Insulation Factor * Volume * ΔTemp = .1 * .3398m3 * 120C = 4kW
Cooktop Surface = 36" X 24" (4 pot)
Optional Oven Volume = H x L x W = 6" x 24" x 12" = 1ft3 (2 pot)

Daily Heat Loss = Insulation Factor * Volume * ΔTemp = .1 * .3398m3 * 120C = 4kW
Daily Temp Loss = Heat Loss * Rate = 4kW * 120C/22kW = 21.82C or 40F

Oven Cost
Insulation = Top+Bottom +Front+Back +Left+Right +Insulative +Leg*4
Thermal Storage = MetalBox  +Sand/Brick
Heat Source =Wire = 3ft*8*8*Rate = $100
Oven Cavity MetalBox = H x L x W = 6" x 24" x 12" = $


I wonder what the cost would be and what the cost is to heat with solar panels or Rocket Stove?

I've been thinking of implementing a similar idea for my camping trailer, which I summarized very briefly at https://permies.com/t/206979/Sand-battery-liquid-air.

where abouts are you? My software can model pretty accurately how much power a panel would produce anywhere...
