I think your MDF may continually draw heat out since it is a solid type material panel.

I have 3kw oven that is a 2" foam core with thin sheet steel skins. It's 4m long x 1.1m wide x 1.1m high.

It will heat up to 100C in about 45 minutes with small light moulds inside.




For me in Australia 3kw has to run on 3 phase power. If it were 2kw then normal household single phase is ok.

Here most households don't have 3 phase whereas industrial workshops usually do.
