I had PE Pacific insert installed mid Feb. last year. This is the first year I have been able to truly enjoy it and get a good idea of how much money I am saving. My house is two story 2300 square feet, open floor plan. All electric with Bryant heat pump. My average electric bill this time of year and frigid temps we are having was @350.00 dollars. Have been burning pretty much non-stop. Electric bill came today. $165.00 dollars. Just a thought for those trying to decide if its worth it. House is warmer with good fire and heat pump set to run only a few hours at night. Peace of mind having a backup if electric goes out. I am now convinced this is the only way to a warm cheap winter!
