Plug block heater into "shore power"?

[Greenie]

I live in Maine, north of Brian and I just checked my last electric bill .... 30 cents per kilowatt hour! A 1,000 watt block heater costs 30 cents an hour to run. 8 hours (on all night, $2.40). I would put a timer on the outlet so the block heater would run 2 hours (60 cents) just prior to your next expected use.
I'm shocked at 30 cents a KWH... I would have guessed 16 cents a KWH...

Someone's gotta pay for the "Green New Deal" scam.

And MAKE SURE you use a big enough extension cord going to your truck/BHeater to carry the current!!!
I nearly learned the hard way!!! Once I had a 150' 16 ga cord i used several times. Plugged it in the garage, out to my truck, let down garage door, went to bed. Next morning went to garage & garage was full of smoke, lots of smoke!!! My 20amp hadn't tripped & wall plug nearly was on fire, wall all black!
Now I use nothing but a 12ga extension cord!!!!

More important is the contact surfaces and tension inside each plug, socket and receptacle in the chain. (Especially the one at the truck.) #16 is too small for 1000w at 150'; making enough heat to really highlight the former problem. Bad enough contact surfaces with #12 can yield the same outcome.

It would take a short-circuit to trip a 15-20A breaker with these small heaters.

You could get a 30A RV extension cord if you want to be sure you don't overload the cord, and adapt it to a 15A plug at the truck.

The power strip has 15' cord that will reach.

I have seen a few of our block heaters of 600 watts as well as the 1000 watt heaters.

Those cheap 600 watt heaters don't really do a very good job when it's cold enough to actually need one. Stick with the 1000 watt heaters only.

Yeah no p;oint in using a 600watt heater, I was saying I've seen some 600 watt heaters.
Bought one at NAPA yrs ago, got to shop & realized they had given me a 600 watter, carried it back & got the 1000 watt one like I thought I was buying.
