Actually, I am trying to create a constant temperature chamber kept at 25 C, in a way that as the temperature goes below 25 C heating element should heat to bring the temperature to 25 C and if it goes above the fan will start to cool it down. Well I have made the arrangement for the cooling fan and it seems to be working, I am now looking for a heating element online. I have found a couple of them given below. I have to connect it to the relay and hence I would like to know if someone can suggest to me which one should be a good heating element. I am trying to run the chamber on Arduino Mega and will be needing a 12V heating element.
You must already know the number of watts needed to keep your device at the temperature you need, so what is the problem? Is the problem the physical mounting of the resistor? IS the problem of circulating the heat? You already have a fan.

Hi!
Thanks for the reply, the issue I am worried about is the connections since I have to connect the relay connection of ON and COM. I can't ground any connections, but most of the heaters which I was looking for had 220 V high voltage way more than 12V or they had a grounding which I will not be able to connect to relay module
Your picture shows a 24 Watt adapter, so about 20 Watts max for your heater, 7.2 Ohms. 1.667 Amps?
What is the size of the chamber? Is it insulated? What is the ambient temperature outside the chamber?
Hello!
So I am trying to create an environment chamber where if the temperature is below 25 C, the heating element should heat the chamber and if the temperature is above 25 C, Now the fan I am using is working and the connection seems to be going well so far, though there is some overshoot, I think I can make it work, I am looking for a similar connection like the one above for a heating element which will be connected to the relay at COM and ON. I am not sure whether the connection is possible but please let me know if you have any suggestions about which heating element would be best, here I am using Arduino Mega 2560, and the voltage max under consideration is about 12V.
