While a 1700w electric radiator can heat a 20m2 room comfortably, a 2000w fan heater will usually only be sufficient for personal heating, failing to keep even small rooms at a comfortable ambient temperature and that's before taking into consideration the costs of keeping the heater running all day.
How many watts does it take to heat 250 square feet?
In the US, running a 2,000W heater will cost $0.26 per hour. That means that running a 2,000W heater for 24 hours will cost $6.24 per day.
How much does it cost to run a 2kW heater per hour?
That means that a 2kW heater will cost 34.40 pence per hour to run. How much does it cost to run a 2000 Watt heater for 24 hours in the US? In the US, running a 2,000W heater will cost $0.26 per hour. That means that running a 2,000W heater for 24 hours will cost $6.24 per day.
How much power does a 2kW heater use?
Multiply the input power in kW by the price of your electricity per kilowatt hour (kWh). Example: 2kW x 28c per kWh = 56 cents per hour. Now that you have your kWh rate, you can multiply this by the number of hours you are using the appliance to calculate your daily running cost.
How many watts does it take to heat a room?
When sizing an electric heater, a rule of thumb suggests the unit needs to consume 10 watts of power per square foot of room area being heated. Since one watt of electricity produces 3.4 BTUs of heat, 10 watts of power equates to 34 BTUs of heat output for each square foot of room area.
Is a 1500 watt heater energy efficient?
Most of them have a maximum power input of 1,500W. This pretty much equates to 1,500W or a good 5,000 BTU/hr heating output since electrical energy is converted to heat at nearly 100% efficiency. It costs about $0.20 per hour to run an electric space heater at the full heating output.
Are 1500 watt heaters safe?
A 1500 watt space heater (on high setting) will draw 12.5 Amps. Power strips, power taps, and even plug-in type air fresheners should not be used with space heaters. Space heaters should be plugged directly into a sound 120 volt wall outlet. Also, always monitor the temperature of the plug frequently.
