[Shop-talk] Comparing kerosene & electric shop heater costs

[jamesf at groupwbench.org (Jim Franklin)]

Since my tools are rusty enough, I'm thinking of using electric heaters in the
garage. Can someone confirm my math here?

Kerosene is about 135,000 BTU per gallon. Running a 45,000 BTU heater for 3
hours =  $4 or so.

Running a 45000 BTU electric heater uses 13Kw, for 3 hours at my 12 cents/Kw =
$4.68.

So neglecting infrastructure costs, it'd be about even....right?
