7800 watts per hour to heat the tank to its required 60 degrees celsius. Therefore if you have a 120 litre tank, your hot water requirement is 7.8Kws. If you had a 300 litre tank, your requirement would be 19.5Kws.
How many watts does a refrigerator use?
The average home refrigerator uses 350-780 watts. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it. Different types of fridges have different power requirements.
Is it better to boil water or microwave?
It is better to heat on the stove or in an electric tea kettle. When water is boiled on the stove the water boils evenly and all of it boils. In the microwave the water only boils where the microwaves have hit it so you can have cold spots throughout the water.
Is it OK to boil water in microwave?
Yes, water can be boiled in a microwave using a microwave-safe container. Use a wooden stick (like a chopstick or coffee stir stick) in your microwave safe container to prevent superheated water.

How much energy does it take to evaporate a gallon of water?
It takes 8,092 BTUs to evaporate one gallon of water. Natural gas has a heating value of 1,000 BTUs per cubic foot (1 Therm = 100,000 BTUs). Approximate cost of natural gas is $0.50 per Therm.
What is the latent heat of vaporization for water?
For the water substance at 1 atm and 100 °C (the boiling point of water at 1 atm), the latent heat of vaporization is 2.25 ÷ 106 J kg21. The latent heat of condensation has the same value as the latent heat of vaporization, but heat is released in the change in phase from vapor to liquid.
What is the value of specific heat of water?
The exact value of the specific heat capacity of water is 4182 J/kg°C. Now, water is quite commonly occurring and an important substance in our life. Therefore, there is a special way to identify the total amount of heat energy needed to raise one gram of water by a calorie (one degree Celsius).
Does boiling a full kettle use more electricity?
Let’s say 80% of kettles are overfilled by treble the quantity of water needed. That means overfilling translates to 3.2% of our domestic electricity bill.” So by using our kettles more effectively, we can potentially make decent savings.
How many watts does TV use?
Modern TVs use, on average, 58.6 watts when in On mode and 1.3 watts in standby mode. The power consumption of modern TVs ranges from 10W to 117W (0.5W to 3W on standby). On average, TVs consume 106.9 kWh of electricity per year, costing $16.04 annually to run in the US.
Is it cheaper to boil a full kettle?
It’s more expensive to boil a full kettle than a half-full kettle, because you’re using more energy to boil more water. If you’re boiling a full 3kW kettle, it could set you back about 42p each time, because you’re using about 0.225 KWh.
Does salt boil water faster?
When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said.
How long should you boil water to purify?
According to the Washington State Department of Health and the United States Environmental Protection Agency, you should bring the water to boil and keep it rolling for one minute to purify it. At altitudes above one mile, 2,000 meters, you should increase the rolling time to three minutes.
How long does 1 Litre of water take to boil?
It will take about 8 to 10 minutes to bring 4 cups (1 liter) of water to a boil, depending on the stove. Usually, it’s 2 minutes per cup of water, depending on the stove. On a propane stove, it takes 8 minutes to boil 4 cups (1 liter) of water.
Is it cheaper to boil kettle on hob or electric?
If it’s full of limescale, you use more energy to boil the same amount of water. Because gas is cheaper than electricity, it works out slightly cheaper to boil water on a gas hob than using an electric kettle, as long as you are boiling just the quantity you need and switch off the hob as soon as it has boiled.
