Efficiency Saves You Money
Understanding energy star rating and efficiency of your heating systems can help you save money. The bottom line is fuel efficiency saves money - the more fuel efficient the system, the more money you save over time.
How much energy you save will vary based on your use and the climate, with colder areas likely saving more. Features that improve boiler efficiency include electronic ignition, which eliminates the need to have the pilot burning all the time, and technologies that extract more heat from the same amount of fuel.
