Block heater amps/watts.

Hey hey, my boss is wondering how much power my block heater is using. I am an electrician and could meter it I just havn't had the chance. Does anyone know off hand? Thanks

 

Tell him 2 watts.

 

Lol it's a she, and they would probably believe it. "Less than a lightbulb."

 

OK a 25 watt bulb. My guess pretty close to 1000 watts restive heating is an energy hog. Guess you'r not in QC. or no one would care never seen so many homes with electric heat.

 

Give me 10 minutes and I'll tell you.

I have a heater unused in a box. Gonna put the clamp meter on one of the leads and plug it in.

 

You over bid.

The heater (Toyota block heater) pulls 3.47 amps @120 volts.

That's about 416 watts of power it's using. It's the same as using 7 bulbs at 60 watts each. Pretty expensive actually.

 

Thanks for checking Mike. 400w is less than I thought for a bigger block, but still wouldn't want to leave it plugged in all night.

 

My son has an F-250 7.3 liter diesel, he use to plug into my garage circuit. I ended up putting a timer in. It would come on 2 hours before he left for work.

He never knew it was there. The truck always started

 

Yikes, those diesel heaters can be over 1000w!

 

I agree. A timer is the way to go.
