Thank you very much Thomas for your question. The power supply has 12 and 24 volts. so you can use both variants. But if you only have a 12v power supply, you have the option of using a 12v fogger but you have a 24v fogger than use now a converter.
I've been wondering for a while how the Mystfire or Dimplex work. Thank you very much for the information and the process. But why do you need the heater?
