Our last bill from our ripoff supplier was $3.89 per gallon. My wife called, which she does every time and they knocked $1.00 per gallon off the bill just for asking. It's always something like that. I pity the folks who just pay the bill. Before the next delivery we are going to switch suppliers.
A year and a half ago the price went over $4. We put in a heat pump and have been happy ever since. It will pay for itself in about 3-4 years. Still have the propane for heating water and for when the temps get too low for the heat pump to be efficient. I've got it set to switch to propane automatically when the temps fall below 30 deg. When it gets to about 32 it takes a long time to heat the house from 68 to 72 in the mornings.
