Water Heater Power Consumption Calculator

Formula to calculate electricity or gas consumption of water heating.

Water heater power consumption calculator.

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. E c v deltat pr where e energy in kwh c specific heat of water 4 187 kj kgk or 1 163 wh kg c v volume of water to heat deltat th tc th temperature of hot water. Water heaters depending on its capacity consumes between 1000 watts and 6000 watts. Also you can find how much power does your water heater consume.

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 usage calculator for water heater gives you the total energy consumed by them. The main reason for power consumption is mostly you forget to switch off the heater after reaching the point. 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.

The comparison assumes a storage tank water heater as the input type. 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. Water heater power consumption. A simple formula to estimate the energy required to heat a volume of water is.

Note that the electricity consumption per day is lesser than the per hour consumption it means we are operating it for only 45 minutes. Select air conditioner clothes dryer clothes iron dishwasher electric kettle fan heater microwave oven desktop computer laptop computer refrigerator stereo receiver television toaster oven vacuum cleaner washing machine water heater. Wattage is the rate at which any appliance consumes power. The water heater consumes 270 units for one year while operating it in 45 minutes per day.

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. For example a 1500 watt hair dyer consumes 1500 watt of power every hour. They typically use low power heating elements about 1 kw to 1 5 kw and can provide hot water long enough for hand washing or if plumbed into an existing hot water line until hot water arrives from a remote high capacity water heater.

Keep in mind however these models also to cost more to purchase and may require. 64 energy factor 0 92 electric 0 61 gas energy cost 0 06 per kwh 60 per therm. To calculate your water heater power consumption and interpret the results correctly you need to know and understand the following four parameters. Quantity of water heaters to be purchased unit s 1 unit see assumptions for various daily water use totals.
