Convection space heaters heat up a room by heating up the air most common convection space heaters will use around 1500 watts.

Electric heat wattage calculator.

Space heaters are portable electric devices used for heating up a single room or an area of the house. The power p in watts w is equal to the squared voltage v in volts v divided by the resistance r in ohms ω. For instance a 2 foot long baseboard heater would emit around 500 watts. A 4 foot baseboard heater would emit 1 000 watts.

Watt is a unit of power within electrical systems wattage corresponds to the amount of power that an electric device uses per second. 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. The power p in watts w is equal to the current i in amps a times the voltage v in volts v. If you re replacing an older heater get the same wattage and voltage.

Multiply the area in feet by 10. The power p in watts w is equal to the squared current i in amps a times the resistance r in ohms ω. Garage door opener. Element electric fry pan.

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. In other words a 1 500 watt heater will be great for a 250 square foot room with central heat. Ac three phase amps to watts. Heating power can vary depending on the make and model of the baseboard heater so consult its documentation for exact heating specifications.

The power p in watts w is equal to the power factor pf times the phase current i in amps a times the rms voltage v in volts v. P w pf i a v v. Cfl light bulb x4 15 watt electric water heater. Electric heater room size calculator.

If that same room had no other source of heat you d need a 2 000 watt heater. Ohms is a unit of electrical resistance the greater. Typical baseboard heaters put out 250 watts per foot. For the sake of our example let s assume that the room has normal specifications.

Household utility furnace fan gas or fuel only sump pump 1 3 hp well pump. In general the power required by electrical heating is calculated in watts. If you re replacing an old heater you must match the old heater s voltage. P w i a v v.

Dc amps to watts calculation. Ampere or amp is a measurement of electrical current amps represent the rate at which electricity flows. Volt is a measurement of voltage volts represent the electrical potential difference or pressure. Room air conditioner 10 000 btu central air conditioner 24 000 btu box fan 20 ceiling fan.

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.
