Portable electric heaters are perfect for heating smaller areas, rooms or garages. There are basically four types: quartz, infra-red, ceramic and wire element. Infra-red heaters have no fan thus no moving parts where the other three have fans to force air past their heating elements. These require no venting and can be used in enclosed areas. They are 100 percent efficient, that is , they output 100 percent of the energy that is input. Unlike vented gas heaters which exhaust a certain percentage of hot gas (energy) outdoors. They are relatively inexpensive to operate. Below is some information on how to calculate the cost to operate an electric heater:
First, you 'll need the Kilowatt Hour rate from your electric bill. This can be found by adding the energy cost and the distribution cost. For example last month mine was .093503/kWh.
Multiply the Watts of the heater (usually found on the back of the unit) by the Kilowatt per hour cost divided by one thousand. Below is an example for a 1500 Watt heater: 1500 W x .093503 kWh / 1000 = $0.14 .This heater would cost about 14 cents per hour to operate or $3.37 a day. That is, if it runs continuously. Most heaters have thermostats and will cycle on and off thus reducing the total cost.

∙ 12y agoFind the rating plate on the unit. It should give you the amp loading. Multiply this by voltage ie; 240v x 10amps (for example) = 2400 watts. Therefore, if the unit is running for an hour, it uses 2.4Kw/h.

How many btu per kw?
One KW of electricity will give you 3,412 btu of heat.
What is electric water heater which used in house?
An electric water heater in a hot tank is called an immersion heater and many of those run at 3 kW with a thermostat to control the max temperature. Power showers use a type of water heater that heats the water at the point where it is used, without a tank. They run at 6-8 kW and are also controlled by a thermostat.
How a electric heater works 2 references?
An electric heater is a resistor that dissipates electric power when a voltage is connected across it and a current flows through it. The amount of power in watts is equal to the voltage times the current in amps. Typical space heaters for use in the home are 1.5 kW to 3 kW to heat a single room.
How many tons of a c required for 950 kw electric panel room?
Just make sure it's well ventilated, with fans if necessary, to take away any heat generated, otherwise there is no need for a/c if it is a room without people in it.
What is the calculated amperage for an electric range rated at 16 kw?
16 kW at 240 volts runs at 16000/240 amps, or 67 amps.
How much Kw is required to run an electric motor producing 800 HP to run a 35 metre yacht?
600 KW
How many kw are required to run 200 hp electric motor?
200 hp requires about 149kW
How much heat energy is produced from 1 kw electric energy?
That depends on how long the 1 kW is applied. Please note that kW is a unit of power, not a unit of energy.In general, 1 kW of electrical energy can be converted into 1 kW of heat - if used in a heater. With a heat pump, 1 kW of electrical energy can, in fact, pump several kW of heat energy.
How much energy do you need to build a small town of about 500 people?
If the town has natural gas for heating, then the power needed per household is between 5 kW and 10 kW. If only electric heat is available, then the combination of electric resistance (auxiliary - from 7 to 10 kW for small residential units) heating, combined with electric clothes dryer (from 2 to 5 kW), electric water heater (from 2.5 to 7.5 kW), and stove (5 kW to 7.5 kW) totaling a min of 15 kW to a max of 20 kW. That would put the max power requirements between 5,000 kW and 10,000 kW. As a matter of reality, a diversity factor of .6 to .7 would reduce the max power to 3,500 kW and 7,000 kW.
How many KW does it take to run 2125 horsepower?
2,125 hp equates to about 1,584.6 kW.
What is the tonage for Goodman air handler A42-10?
3.5 tons air conditioning. 10 Kw electric heat.
How many BTU would be produced in 12-kw electric heater?
40956
How many btu per kw?

How many kWh in 750 kW?
KWH = KW times hours If you run a 750 KW load (lights, motors, so forth) for 1 hour, you have 750 KWH. If you run it for 1/2 hour, 750 KW X .5 hours = 375 KWH. If you run it for 5 hours, 750 KW X 5 = you do the math.
How many BTU would be produced in a 12-kw electric heater?
40956
An electric motor under steady load draws 9.7 amperes at 110 volts delivering 1.25 hp of mechanical energy What is the rate of the heat transfer from the motor in kW?
As the motor is drawing 9.7×110 = 1,067 watts (or 1.067 kW), and delivering 1.25×746 watts (or .9325 kW) of mechanical energy, it should release 1,067-932.5 = 134.5 watts (or .1345 kW) of heat.
