I'm not sure how many watts the regular block heater is that I still have in the box.....nor the one in my dad's car.....I do know it doesn't make the engine warm to the touch even if on all night. I'll have to use my "Kill a watt" on it to check how much it draws to make a comparison. My hose one draws 375 according to the imprint in its "block". The coldest it got here last winter was -13.....that was the day I had to go to work.....and the day my 4 year old OEM battery didn't hold out for more than 12 seconds of cranking.

I'm pretty sure leaving my hose-heater on for 3-4 hours up to when I start the car is going to result in effortless starting, based on how hot everything was in under an hour...

375watts can be run for 4 hours a day at a cost of less than 20 cents around here....so its pretty negligable. $6 a month is nothing compared to what my air conditioner uses....more like $2 a day
