Water Heater Power Consumption Calculator

Keep in mind however these models also to cost more to purchase and may require.

Water heater power consumption calculator. If you use a 611 watts heater in this example then it will be about enough to reverse this cool down from 105f to 103f by heating the water back up from 103f to 105f. The water heater consumes 270 units for one year while operating it in 45 minutes per day. 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.

Water heaters depending on its capacity consumes between 1000 watts and 6000 watts. A simple formula to estimate the energy required to heat a volume of water is. Enter the wattage hours of usage and cost per kwh. Wattage is the rate at which any appliance consumes power.

The main reason for power consumption is mostly you forget to switch off the heater after reaching the point. Click calculate to find the energy consumption of a water heater using 4000 watts for 3 hours a day 0 10 per kwh. Also you can find how much power does your water heater consume. To calculate your water heater power consumption and interpret the results correctly you need to know and understand the following four parameters.

Using the water heating power calculator above 250 us gallons start temperature 103f end temperature 105f 120min tells us that a heating power of 611 watts is required. A typical water heater will use around 4000 watts. A typical water heater consumes 3000 watts of power.

For example a 1500 watt hair dyer consumes 1500 watt of power every hour. The comparison assumes a storage tank water heater as the input type. 64 energy factor 0 92 electric 0 61 gas energy cost 0 06 per kwh 60 per therm. Average daily usage gallons per day gallons.

Formula to calculate electricity or gas consumption of water heating. The energy usage calculator for water heater gives you the total energy consumed by them. According to the department of energy tankless heaters are around 24 to 34 percent more efficient than heaters with tanks in homes that use 41 gallons or less of hot water per day or 8 to 14 percent more efficient in homes that use 86 gallons of water or more.
