I need to heat up an area 0.5m^3 (100cm x 100cm x 50cm).

Would anybody know of any formulas I could use to calculate what wattage heating element id need to heat this area up to 100 degrees C within say 30 minutes.

Thanks

eg. If the material has a density of 7000kg/m^3 then its mass will be 0.5 x 7000 =3500kg

If its SHC is 500J/kg then 3500 x 500 x 100(temp change) Joules are needed = 1.75 x 10^8 J This energy supplied in 30 mins means a power of 1.75 x 10^8/(30x60)

=97kW
