There is nothing "frugal" about plugging appliances into electrical outlets, either way you pay... It is splitting hairs to incur the costs of purchasing new electric heaters of sorts for every room in the house and then the cost to run them to boot compared to hanging the oil gun and going away for a long weekend or weeks worth of vacation...
Well, you said it best, it is about splitting hair, and this has been a nice healthy debate, and I appreciate you being informative and polite, but come on, I mean I don't drive a car not because gas is too expensive, but simply because of a DUI, this is Pennsylvania you know, it's a racket !
My girlfriend's mom promised to consider a coal stove but only after I pass her version of a sobriety check, she wanted me to move ashes from the stove to the outside, without spilling any on the carpet, and she allows me to hold the beer in the other hand during the test. However, she insist it's done at random times but so far she only asks me to do the test during times when I am wasted.
Time for another beer
