Electric Heat Wattage Calculator

With 144 square feet the required wattage is 1440 watts which means you could heat the room with a single 1500 watt baseboard heater or two 750 watt heaters.

Electric heat wattage calculator.

Watt is a unit of power within electrical systems wattage corresponds to the amount of power that an electric device uses per second. Volt is a measurement of voltage volts represent the electrical potential difference or pressure. For instance a 2 foot long baseboard heater would emit around 500 watts. Garage door opener.

Multiply the area in feet by 10. Dc amps to watts calculation. In order to calculate the heating required we must consider the size and volume of the house orientation size and number of windows type of insulation found in the walls and roof etc. Space heaters are portable electric devices used for heating up a single room or an area of the house.

Typical baseboard heaters put out 250 watts per foot. Ac three phase amps to watts. Household utility furnace fan gas or fuel only sump pump 1 3 hp well pump. Room air conditioner 10 000 btu central air conditioner 24 000 btu box fan 20 ceiling fan.

Convection space heaters heat up a room by heating up the air most common convection space heaters will use around 1500 watts. Cfl light bulb x4 15 watt electric water heater. Element electric fry pan. Ac single phase amps to watts calculation.

For the sake of our example let s assume that the room has normal specifications. In general the power required by electrical heating is calculated in watts. If you re replacing an older heater get the same wattage and voltage. Electric heater room size calculator.

The power p in watts w is equal to the current i in amps a times the voltage v in volts v. The power p in watts w is equal to the squared voltage v in volts v divided by the resistance r in ohms ω. If that same room had no other source of heat you d need a 2 000 watt heater. Our electric heater room size calculator will provide you with an estimate of the minimum size and quantity of radiators panel heaters or storage heaters your room will require to establish and maintain a temperature of 21 c within the uk based on a standard ceiling height of 2 3m.

In other words a 1 500 watt heater will be great for a 250 square foot room with central heat. The power p in watts w is equal to the squared current i in amps a times the resistance r in ohms ω. Ohms is a unit of electrical resistance the greater. A 4 foot baseboard heater would emit 1 000 watts.

If you re replacing an old heater you must match the old heater s voltage. The power p in watts w is equal to the voltage v in volts v times the current i in amps a. P w pf i a v v. Ampere or amp is a measurement of electrical current amps represent the rate at which electricity flows.

Click calculate to find the energy consumption of a space heater using 1500 watts for 5 hours a day 0 10 per kwh.
