To heat 140 gallons of water, the required wattage depends on the temperature increase needed and the time frame for heating. Generally, it takes about 8.34 BTUs to heat one gallon of water by one degree Fahrenheit. For example, to heat 140 gallons by 50°F, you would need approximately 62,520 BTUs. Converting this to watts, you would need about 18,300 watts if heating over one hour.

How many watts of heat to raise 55.32 gallons of water to 160 degrees?

A watt is a unit of power: what is required is probably the amount of energy - which is measured in joules.


How many gallons can a 50 watt heater heat up in a freshwater tropical fish tank?

I would not try to heat a tank any larger than 8 gallons with a small 50 watt heater. The difference in price between a 50 watt and a much more usful 150 watt heater is not much. I'd check things out before I got a very small heater that may have to work very hard to do its job.


What is the most efficient watt to heat calculator available for determining the energy required to heat a specific space?

The most efficient watt to heat calculator for determining the energy needed to heat a space is the BTU (British Thermal Unit) calculator. It measures the amount of heat energy required to raise the temperature of a specific space.

How many gallons of diesel in 1 mega watt?

The amount of diesel required to generate 1 megawatt of power depends on the efficiency of the diesel generator. On average, it takes about 0.25 to 0.30 gallons of diesel per hour to produce 1 kilowatt of electricity. Therefore, to produce 1 megawatt (1000 kilowatts) of power for an hour, it would require around 250-300 gallons of diesel.

How much heat does one watt produce?

About one watt of heat. A 1500 watt heater will warm a 400 square foot room in the winter months. one watt is a very small volume of heat.AnswerHeat is measured in joules. A watt is equivalent to a joule per second. So your answer is that a watt produces one joule of heat every second.

Does a 100 watt bulb produce more heat than a 25 watt light bulb?

Yes, a 100 watt bulb produces more heat than a 25 watt bulb because the higher the wattage, the more energy is being converted into heat. In this case, the 100 watt bulb will generate more heat compared to the 25 watt bulb.


How many watts per hour with a heatsink attached?

It depends on the size of the heat sink. Heat sinks are available in many sizes, the smallest being suitable for fitting to a single transistor. A heat sink is rated by the temperature rise in degrees C per watt of dissipated power. The smallest heat sinks are rated at about 20 degrees per watt while larger ones provide 1 degree or less per watt.


Does one watt is the work or energy required to produce one watt of power in one second?

No. One watt is one joule/second.
