Find the cost per kwh on your bill.
Water heater power consumption per hour.
Water heaters running on 120 volt power have a long recovery time which is impractical for most households.
Pool heat pumps have an average electrical input ranging from 5 7 kw per hour with a corresponding output heat of 30 40kw so essentially they produce a whole lot more energy than they pull which is a good thing.
Water heaters depending on its capacity consumes between 1000 watts and 6000 watts.
Enter the average power consumption of the device in watts.
Most water heaters include a label listing the annual.
You should get a rate betw.
The energy usage calculator for water heater gives you the total energy consumed by them.
Since pool heat pumps use minimal amounts of electricity to harvest and transfer heat they typically have the highest cops ranging between 5 0 and 6 0.
A typical water heater consumes 3000 watts of power.
That is the power used for a period time.
Enter the cost you are paying on average per kilowatt hour our caculators use the default value of 0.
Electric water heater operating cost.
If the company charges 20 cents per kwh then that 100w globe costs you 20 cents to run for 10 hours 10 cents for 5 hours etc.
Power is measured in watts so if it runs 60 minutes it will use 3600 watt hours.
Hours used per day.
A 50 gallon 5 500 watt water heater with a 90 ef and an electricity rate of 16 per kilowatt hour will cost 781 to operate each year.
So the 100w rated globe above needs to run for 10 hours to use 1kw of power.
Also you can find how much power does your water heater consume.
30 minutes per day is 0 5 power use watts.
120 volt elements consume 1125 watts while residential 240 volt heaters use 4 500 watts.
The water heater consumes 270 units for one year while operating it in 45 minutes per day.
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.
The main reason for power consumption is mostly you forget to switch off the heater after reaching the point.
Note that the electricity consumption per day is lesser than the per hour consumption it means we are operating it for only 45 minutes.
Divide cost by kwh used.
The power company will charge you per kilowatt hour kwh.
For example if you pay 1 per therm and use a heater that consumes 205 therms per hour for three hours per day your totals come to about 62 per day 18 70 per month and 224 per year.
Take the total cost all taxes add ons etc the amount you pay.
