Power Use (Watts): Enter the average power consumption of the device in watts.
Price (kWh): Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0.10 or 10 cents. To find an exact price check your electricity bill or take a look at Global Electricity Prices.
Space heaters can be expensive to run and are generally less efficient than central furnace heating, however if you are only in a single room of the house during winter and do not want to heat up the entire home than a space heater can cost less to operate. You can lower the temperature of the entire house and set up a space heater in a room you are in, if you have good insulation and can retain heat in a single room this would save you money. There are some models of space heaters that are more environmentally friendly and use less energy, they may use as little as 400-500 watts compared to regular convection heaters. Space heaters can be dangerous if they are not carefully monitored, always read the manual of your space heater and make sure you are using it properly.
