geesh, you do realise how much it cost to run the block heater right?????
Must really be a tight wad!
My math tells me about $0.60/day @ $0.10/kwh and a 1500 watt user running approx 4 hrs a day. Youre right, that is chump change,
unless I used your theory and plugged in anytime below 40°F, then it would be approximately $20.00/month for 9 months.
Hence I only plug in when its cold out, which is under 10°F. -popcorn
I was a farm boy raised in ND, we had diesel engines out the wazoo and I have probably a much different perspective of what cold is than do most folks.
