<x-charset iso-8859-1>I was assuming 12V at the heater - do you get as much as 14.1V there when running with old wiring? I've never bothered to measure it. I just used V-squared x R, which gives 14 Watts for 12V and 10 ohms. Good enough for a working value as most are much higher resistance than that now. Never got near enough to a new one to know it was only 45Watts, hence the admission of a guess on that. The easy improvement is to put a small 12V computer fan on the shelf and blow air at it, using the HRW wiring/switch to work it. If you need heat too, a small coil of nichrome wire could add a bit of heat - don't want it red-hot though, for safety. Dave.
