How much electricity does it take to heat 375 cubic metres or 375000 litres of water to 30 degrees celsius?

Question

How much electricity? (kilowatt hours, joules, anything)

Oh, heating it from room temperature i suppose, thanks.

Answer 1

A lot! If your looking to heat that much water you need a heat pump. Unlike tradition heaters these will give more heat out than electricity used. For instance a unit taking 3Kw of electricity can have the heating capacity of about 9Kw

Answer 2

375000 liters, or 375 kiloliters, is a lot of water.  One calorie

is the amount of heat needed to raise the temperature of one

gram of water 1°C. and there are 1000 gm. of water in each

liter, so it will take 1 kilocalorie to raise the temperature of

1 liter by 1°C.  4.184 joules equal one calorie, so 4184 J.

equal one kilocalorie, so you need 4184 joules to raise the

temperature of each liter by 1°C.

You have 375 kiloliters, so you need 375000 times 4184,

or 1.569 gigajoules (that is BILLIONS of joules) to raise the

temperature of that much water each degree C, not counting

any heat loss by evaporation or other method.

Since 1 kilowatt-hour equals 3.6 megajoules, it takes 435.83

kilowatt-hours to heat that much water each degree.

So find the number of degrees you want to heat that much

water, and multiply the number of degrees by 435.83 to

get the total number of KWH needed to heat the water.

Hope this helps - you need lots of energy!
