300 watts at 12 volts is not a not of heat

Watts = volts times amps

so

AMPS = Watts divided by volts

so amps = 300 / 12 or so = 25 amps.

25 amps is plenty lots of current for all the good it's going to do you.

Stay clear seems to be the advice from all the common experiences.

So probably not worth bothering then? Are defender heaters as bad in winter as people make out?

was given one of them heater thingies by previous owner who seemed to swear by it. Never got round to fitting it yet as i've never really needed it. The heater seems to be ok as far as i can tell, but I drive with the window down in most weathers apart from pishin rain, then it's only slightly down

Assuming the thermostat works and the engine gets up to heat and the heater matrix isn't choked and the fan runs, the Defender heater is fine.

Run it all the time full hot, and divert the heat to the screen if you get too hot.
