I'd like an outdoor temperature controlled timer with a straight line mapping.
5hrs @ -25° C
4hrs @ -15° C
3hrs @ -5° C
2hrs @ 5° C
1hr @ 15° C
I've used 3½ hours most of the winter. It's a 400 watt heater in a 3.3L V6. It seems to top out at around 30°C (86F) if you leave it on long enough. I'll back it down to 2 hours at the end of this month and then down to an hour at the start of May.
