Which heating element to maintain 32.5 degrees in a 1 liter container?

Question

Electronics

There is a capacity of 0.5l. It will store the contents, but it is important to heat at room temperature to 32.5 degrees and maintain constantly. Preferably without jerks. Making a foam container is not a problem to reduce heat loss

. Which heating element and what power should I use? The rate of heating is not important. Keep the temperature for example for several days or weeks.

As an option, I look in the direction of the IR film (but for a warm floor it is a very large area), and on Ali Express there are mats for 5-10W, approximately 15x15cm in size.

The arduino can control this, the thermal cutter is also not a problem. The main thing is where and what heating element to get.

I will be glad to any recommendations.

Answer 1

Aquarium heater operates between 20 - 33 °C

Answer 2

Buy yourself a courtesy

Answer 3

it is necessary to calculate the heat loss through the foam container. the thicker it is, the less power will go through the walls.
plus the heat consumption for the rest of the elements, I understand that the liquid in this container will not be constantly located, is it a storage device of some kind of system ??
this will be the basis for choosing the power of the heater.
take, as a standard, a triple power reserve and choose.
type of heater to the light bulb. the film will also go if there is enough space.

Answer 4

You can use some kind of heater for ultrasonic baths. Example

Answer 5

Nichrome or a nichrome spiral can be heated in any way, even from batteries, at least from 220, you can get any temperature, you can get irons, kettles from heating elements

Answer 6

Heater for maintaining the required temperature inside telecommunications and electrical cabinets. Heater power 60W.

And for the company in the same place: a thermostat for adjusting the temperature inside the cabinet https://shop.nag.ru/catalog/33788.klimaticheskoe-o ...
It is possible to buy in different computer firms.

Answer 7

Electric
stove Control through a 220V solid state relay (with switching at zero) solid state relay zero cross (ready ~ 500 rubles or kolkhoz on MOC3061).
Next Arduino with PWM.
