Water Heating Calculator for Time, Energy, and Power
I’m looking at a 50,000 btu boiler with a heat exchanger to heat a 33,000 gallon pool to 90 degrees f. A Watt is named after James Watt hence the abbreviation is a capital W. A thousand of something is a “kilo” for example a kilogram. In turn the abbreviation, for one thousand, is k. And this is 488.36 Kilo Watts of power (since
Boiler horsepower to kilowatts [BHP to kW] conversion tables
How to convert boiler horsepower to kilowatts [BHP to kW]:. P kW = 9.81055407 × P BHP. How many kilowatts in a boiler horsepower: If P BHP = 1 then P kW = 9.81055407 × 1 = 9.81055407 kW. How many kilowatts in 45 boiler horsepower: If P BHP = 45 then P kW = 9.81055407 × 45 = 441.47493315 kW. Note: Boiler horsepower is an imperial or United States customary unit of power.
So a 1,000 watt drill needs 1,000 watts (1 kW) of power to make it work, and uses 1 kWh of energy in an hour. That’s why, if you leave a TV or computer on standby, it is still using power and creating a kWh cost on your energy bill. How many kilowatt hours should I be using each year?
How to calculate the kW required to heat a volume of water
Sep 26, 2012 · One question which comes up time and again is “How many kW do I need to heat up my tank?” If we can calculate the volume of water and the required temperaure rise , we can answer this question. The following formula is used to calculate the power of heating element needed to heat a specific volume of water by a given temperature rise in 1 hour.
What Size Generator Do I Need to Power My Home? | Hunker
In Honda Power Equipment's example, a refrigerator (1,600 starting watts/200 running watts), plus a furnace with a ¼ horsepower fan (1,600 starting watts/600 running watts), plus a television (300 watts flat), a microwave (1,500 watts flat) and five lights (60-watt bulbs = 300 watts) equals to 5,300 watts.
These industrial heaters are used in many facilities for comfort heating, laundry services, and kitchen services. The nature of the facility’s operations will indicate whether the boiler system is steam generating or if hot water system is used. Industrial water heater systems typically heat water up to 230 degrees Fahrenheit.
So, our typical 4500-watt electric heater can make 47 gallons of hot water per hour — about a full tank. Like others, I've wondered why specs often read "Top element: 4500 watts, Bottom element: 4500 watts, Total wattage: 4500 watts".
How to convert amps to kilowatts. How to convert electric current in amps (A) to electric power in kilowatts (kW).. You can calculate kilowatts from amps and volts.You can't convert amps to kilowatts since kilowatts and amps units do not measure the same quantity.
So if your heater element rating was 3.6 kW, your equation would look like this: heating time = 1.867 ÷ 3.6, or heating time =0.52 hours. Therefore, it would take 0.52 hours to heat 20 liters of water, with an element with a rating of 3.6 kW.
