This heater uses 8 watts. Wait until you see what it does at 100...

I have been searching for a way to heat my home using less energy. This heater at 12 volts uses only 8 watts to produce a 15 C gain in the core.

After I burn out the cardboard core, I am going to turn it up to 100 watts. I think you will be impressed at how much heat a 100 watts can get you these days... 😁
