Formula to calculate electricity or gas consumption of water heating.
Water heater power consumption calculator india.
Your water heater is one of the more robust consumers of energy among your home appliances.
We hope these tables charts will help you to better estimate how big and powerful generator you will need as a backup source of power.
An on demand water heater or instantaneous water heater is designed to supply hot water on demand meaning the moment you turn it on in just 5 10 seconds you will start getting hot water.
4000 watt hours per day 1000 4 kwh per day.
4000 watts x 1 hours 4000 watt hours per day.
Energy consumption calculation 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.
Load watts nos of appliances.
Click calculate to find the energy consumption of a water heater using 4000 watts for 3 hours a day 0 10 per kwh.
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.
Let s take an example and say your model uses 600 watts you can find the wattage label that displays the power consumption of the electric water heater look like this or check device manual.
That is why we have decided to create this list of rough estimates of wattage consumption of most common household appliances that people want to keep running at all costs.

Leading electricity distributor in western region of gujarat in india home.
Electricity cost calculation for running various electrical appliances such as ac cooler fan lamp etc can be calculated using this energy consumption calculator.
A simple formula to estimate the energy required to heat a volume of water is.
A typical water heater will use around 4000 watts.
How much does it cost to run a water heater every day.
Monthly energy consumption calculator.
How many kilowatts does a water heater use.
Electronic devices consume electric energy to generate desired output.
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.
To achieve this large amount of heat is supplied to the heating coil in very short time hence their power consumption is more.
In the average home the hot water heater is responsible for about 17 percent of the total energy use according to the department of energy.
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 consumption of electric energy is measured in terms of watt hour.
