Re: Hemi Block Heater

Does any one know how much juice a block heater uses? I work night shift in the dead of winter, with no where to plug into. My idea is to put a deep cycle in the back with a thermostat, and inverter. Then plug up a trickle charger when I'm home.

I can't find the rating for the GC heater. In general, block heaters consume from 200 to 1000 watts.

You can't power the inverter from a cigarette lighter outlet; its fuse limits it to 13 amps = 156 watts. If you connect directly to the battery and draw, let's say, 500 watts, that's 40 amps and you'll drain a 60 amp-hour battery in 90 minutes.

So much for my plan.. I would need 9 batteries to power it during a shift and a week to trickel charge the battery pack back up. Thanks for the advice.. My next idea is a remote start with a timer.
