Electric heater power consumption calculation.

Electric water heaters are typically running for 3 hours a day to heat water newer more efficient models may run for only half the time during each day.

We are open service tech support parts fast lead times from 6 local plants. E kwh day p w t h day 1000 w kw electricity cost calculation.

A simple formula to estimate the energy required to heat a volume of water is. Before going on with the calculations we need to give you a brief about the following points. Dividing by 250 the normal wattage per linear foot equals 6 84 feet of baseboard heater required. The energy e in kilowatt hours kwh per day is equal to the power p in watts w times number of usage hours per day t divided by 1000 watts per kilowatt.

Convection space heaters heat up a room by heating up the air most common convection space heaters will use around 1500 watts. Click calculate to find the energy consumption of a space heater using 1500 watts for 5 hours a day 0 10 per kwh. Rounding up this means that 7 feet or 84 inches of heater is needed. Formula to calculate electricity or gas consumption of water heating.

Click calculate to find the energy consumption of a water heater using 4000 watts for 3 hours a day 0 10 per kwh. The energy e in kilowatt hours kwh per day is equal to the power p in watts w times number of usage hours per day t divided by 1000 watts per kilowatt. Space heaters are portable electric devices used for heating up a single room or an area of the house. A typical water heater will use around 4000 watts.

Electric heaters whether they are fan heaters halogen heaters oil filled radiators or convector heaters are rated in watts w or kilowatts kw find out what your heater is rated at then use our energy calculator to see how much it will cost to run per hour day or week. Choose the space heater you are interested in then simply enter the power rating of the heater in watts your cot per kwh an average cost is pre entered and roughly how many hours per day you will need to run the heater. Electricity bill calculation energy consumption calculation. Standard heaters are not available in this length so in this case a single 8 foot or two 4 foot heaters would be the likely choice.
