Notes:
1) The default Fuel Unit Costs with the "*" are an average price of the fuel in New Hampshire updated  October 6, 2014.
2) The field for "Fuel Unit Cost" can be changed to your local prices.
3) The "Efficiency of Heating Unit" is for an average location of the heating unit and allows changing for location. Units that are located in the living area could be more efficient than the default figures. The loss of heat delivered to a living area would be from units installed in uninsulated basement or a furnace located outside of the home.
4) After you make a change hit the "Recalculate" button, to return to the default values hit the "Reset" button.
5) "Fuel Types" that are underlined in blue are links to listings of New Hampshire fuel sources or information on the fuel.
6) ** Heat Pump efficiency is measured as Coefficient of Performance (COP). A baseboard electric heater has a COP of 1 or 100% efficiency. Depending on system design and performance geothermal heat pumps in the New Hampshire area have an average COP of about 2.75 (275%).
Source: An EESE Board Presentation by Dick Henry showed an average New Hampshire COP of 2.5 (250%), it is felt that this may be on the low side.

How to find what you appliances use for electricity

Here is a great tool for measuring what your appliances are using for electricity and find out what appliances are actually worth keeping plugged in. Simply connect these appliances to the Kill A Watt™, and it will assess how efficient they really are. The large LCD display will count consumption by the Killowatt-hour, same as your local utility.
You can calculate your electrical expenses by the day, week, month, even an entire year. Also may check the quality of your power by monitoring Voltage, Line Frequency, and Power Factor. Now you´ll know if it is time for a new refrigerator or if that old air conditioner is still saving you money.
