Optimal Heater for DIY Oven: Achieving 400 Degrees with Amica 1300W & Suitable Thermostat

Question

Good morning, I wanted to make such a makeshift 'oven' but I would like the temperature in it to reach as much as 400 degrees - whether such an ordinary heater, e.g. maybe reach this temperature? Nowhere did I find information next to the heaters, whether on allegro or in industry...

Xantix · Answer

Because basically the maximum temperature of the heater is the melting or decomposition / oxidation temperature of the material the heater is made of. The value of the temperature that the heater reaches depends on the relationship between the power supplied by the heater and the received by the environment. Not completely. It will heat to the temperature at which the balance between the heat emitted by the heater and the power supplied to it will be established. It depends on the heat collection efficiency how high the temperature will be. The worse the heater will be cooled (e.g. weak air movement, etc.), the more it will warm up. Indeed, in extreme cases the temperature may rise so that the heater will burn.

And will such a heater be able to warm up to 400 degrees without burning?

michallodz · Answer

Someone will help? I don't want to burn my oven as part of testing

vodiczka · Answer

Does this heater in the oven glow or stay dark, and if it glow in a dark cherry color or is it red? The color of dark cherry corresponds to a temperature of approx. 650-700 ° C and red approx. 800-850 ° C
Microwave heaters with hot air glow red, i.e. they withstand 800 ° C. In my microwave oven such a heater burned out after 12 years of work.

michallodz · Answer

As the heaters heat up, they glow with a reddish color.
As for the thermostat, will it be better with a capillary or bimetallic? With the capillary up to 400st I saw on sale but bimetallic probably not - but maybe I'm looking wrong?

vodiczka · Answer

I didn't ask before - you are building an oven at 400 ° C or do you want to raise the temperature in your own? If the latter, make sure it has some plastic elements and that they will not flow, because everything will be hotter, not just the cooking compartment.

michallodz · Answer

Rather, I will build because mine is too small anyway

and after discussion.

vodiczka · Answer

The author of the topic needs 400 ° C and not three times more. He'll build a stove for 1/5 - 1/4 of your price

nares · Answer

Exactly. Maybe a colleague would specify what size (volume) the furnace is to be designed for? If larger than a normal oven, then one suggested heater will definitely not fulfill its role, even in an ordinary oven. It would be necessary to use several such heaters, depending on the volume.

vodiczka · Answer

The necessary minimum power of the heaters depends not only on the volume of the furnace and its charge but also on the thermal insulation and the expected heating time to 400 ° C I agree that one 2-3 kW heater is not enough to heat a 100 dcm? stove in a reasonable amount of time.

michallodz · Answer

Forgive me for being so late but for life The furnace is to be about 40x40x30cm or about 50l and I didn't even plan to do the insulation, but this is not a closed topic

vodiczka · Answer

What is your heating time to 400 ° C? Even an ordinary oven has insulation in the form of an air layer between two sheets. Without insulation, there will be massive energy losses.
