propane cost per month
Reputation: 721. propane is 3 times the cost of natural gas in my neck of the woods in upper township, NJ it would affect my decision on price. I myself would not buy a house that uses propane for heat. you are looking at 3 times the cost for heating say $600 a month for propane versus $200 for natural gas. 04-16-2014, 09:06 AM.
