120 volt elements consume 1125 watts while residential 240 volt heaters use 4 500.

Water heater wattage.

The age and size of your unit the temperature you set it to the amount of water you use in the day and other factors impact the wattage your unit consumes. However often more wattage is required depending on how much you want to raise the temperature. Electric water heater tankless 6 600 w. Electric medium water heater provides an ample supply of hot water for households with 2 to 4 people.

An electric tankless water heater with two elements and labels informing you about 4 500 watts of power consumption of every component will need a maximum of 4 500 watts and not 9 000 watts. This unit comes with two 4500 watt elements and an automatic thermostat which keeps the water at the desired temperature. Electric water heater immersion 3 000 w. Oversink water heater hand wash 3 000 w.

Typically a hot water heater that uses a tank will run for three to five hours per day. So a 4 000 watt heater used for three hours a day at 10 per kwh will cost 1 20 per day about 36 50 per month or 438 per year. Only one is active at a time depending on the temperature in the top or bottom of the tank. Central ac 40 000 btu 6 000 w.

A typical water heater will use around 4000 watts. 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. Click calculate to find the energy consumption of a water heater using 4000 watts for 3 hours a day 0 10 per kwh. For the heater wattage the basic rule of thumb is to use between 2 5 and 5 watts per gallon of actual water volume in the aquarium.

4500 4500 means you have two 4500w elements. Electric medium the rheem performance 40 gal. Enter how many hours the device is being used on average per day if the power consumption is lower than 1 hour per day enter as a decimal. Wattage average monthly kwh usage ceiling fan 60 1 20 clock 2 1 4 clothes dryer 4200 5600 60 300 water heater typical use 2 person 3800 250 350 typical use 4 person 3800 375 525.

So max current draw at any one time will be 4500 240 18 75 amps.
