Not seen this oven in this forum, but some ovens with similar design. This is good small oven and very fast to heat, it heats up +300c in 10 minutes.
The problem is that you have to play with it because it will cut the power off from the top boiler. I would like to modify this oven so that i could bake with it
when the boiler would be on all the time.
If i remember right the maximum temp is around 750f and that is with a thermostat which is cutting the power off. If this could be modified the temps
can be easily +800f. It works on 220-240v and has 1200w, there is setup 1-3. Right now with the issues in this oven i can bake better pies in my normal oven.
If you have experience modding this oven or knowledge for it feel free to post some advice
