    Reduce 12vdc to 6 v dc

    Hi Dazza, Yes it would work, the easy way would be to use one extra glowplug in series with each as a resistors. A glowplug have a dynamic resistance (it changes with temperature) and is not easy to make a good voltage divider with a conventional resistor. The extra plugs can be fitted under...

    Making an electric furnace.

    Hi Dazza, A standard triac circuit would work fine for this. Since the load is resistive the interference will not be too bad. A triac circuit with zero crossing control will run without interference though.
