Tnx for answer.I left power calculations to profesional, and it is 10kW fo 150 l , three phases. Brickwork is done, heat element chanel already cut and shaped. Wool blanket is saved from my old kiln, and since budget is tight I'm going to use it, as carefully as can. I'll pack outer shell out of steel sheet, and seal exposed wool with kind of refractory mortar. As for firing cycles...I have old procesor with only two steps, middle and final temp plato, and shut off, so crash cooling at the end. For cooling hold at,say, 950C , I have to be there and turn on manuelly...

Hi, I am building new electric kiln, 150 l, and 50x50x63 cm, with k26 insulating firebrick, wall 12.6 cm thick, top load, with some ceramic wool insulation of course. What I'm worried about is thermal mass, since k26 is hevier than k23 for example. Would a 6,3 cm thick wall with more wool insulation be better ?
