What a new boiler would do to your oil bill
A high-efficiency boiler burns up to 40% less oil than a conventional one — the same heat out of fewer gallons. Put in what you burn and what you pay, and this works out what that is worth against what the boiler costs a month.
Started at 800 gallons — a typical year for an average-size house around here — and the going rate where you are. Change either if you know better; last winter’s deliveries added up is the best guide.
