Folks,

I want to modify my furnace from Propane to electricity.

First question: can standard incoloy elements handle the temperatures
required? I suppose 1200 deg F to be safe?

They are comparatively cheap and can be custom made to fit the furnace.

Second question: Approx what power am I looking at?
Inner dimensions with lid on is: dia 8 inches , height 10 inches.
Wall thickness 4 inches.
I guesstimate 2 kw will do.

Third question: How do I do the temp control cheaply?
