How To Calculate Power Consumption Of Geyser

110 x 55 x 42 20 790 kilo joules of energy.

How to calculate power consumption of geyser. The graph above shows the way a geyser uses electricity. The unit tested was a kwikot dual 600 200 litres with a 4kw heating element. Enter the average power consumption of the device in watts. 52 kwhday for actual hot water down the drain 30 kwhday for keeping it hot in my airing cupboard 82kwhday.

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. To work out how much your geyser uses you need to just add the two numbers that weve worked out. 30 minutes per day is 05 power use watts. Geyser electricity consumption test day 1.

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. Hence the normal temperature of your geyser is between 550c and 650c. The geyser supplied hot water to the main bathroom of a family of 4 two adults and two children. All four used that bathroom during this test.

Ekwhday pw thday 1000 wkw. The calculation now looks something like this. A 100w bulb when run for 10hrs will consume 1 unit of electricity. The 20 790kj of energy needs to be divided between 3 600 which is the amount of seconds in a day.

Hours used per day. So looking at a month we need to multiple by the number of days 82 x 30 days 246 kwhmonth. But given that your electric bill is going to show kilo watt hours another calculation needs to be made. Cost per unit x geyser usage in mins.

So a 3kw electric geyser will consume 1 unit in 20mins.
