Enter the wattage hours of usage and cost per kwh.
Water heater power consumption per hour.
Electric water heater operating cost.
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.
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.
Note that the electricity consumption per day is lesser than the per hour consumption it means we are operating it for only 45 minutes.
That is the power used for a period time.
Also you can find how much power does your water heater consume.
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.
A typical water heater consumes 3000 watts of power.
Water heaters depending on its capacity consumes between 1000 watts and 6000 watts.
Divide cost by kwh used.
Enter the cost you are paying on average per kilowatt hour our caculators use the default value of 0.
The energy usage calculator for water heater gives you the total energy consumed by them.
You should get a rate betw.
30 minutes per day is 0 5 power use watts.
Most water heaters include a label listing the annual.
Hours used per day.
Take the total cost all taxes add ons etc the amount you pay.
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.
Find the cost per kwh on your bill.
Let assume that your water heater operates 1 hour a day average power consumption of the water heater between 400 to 1300 watts.
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.
Power is measured in watts so if it runs 60 minutes it will use 3600 watt hours.
Enter the average power consumption of the device in watts.
Water heaters running on 120 volt power have a long recovery time which is impractical for most households.
The water heater consumes 270 units for one year while operating it in 45 minutes per day.
The power company will charge you per kilowatt hour kwh.
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.
