You do not mention how much you want to heat the water and in what period of time. But here are the figures: 1 btu = temperature increase of 1* F of 1 pound of water. One gallon of water weighs 8.33 lbs. So a boiler with an output rating of 2,332,400 btu will raise the temperature 1*F in 1 hour. (280,000x 8.33). Boiler outputs are rated in btu per hour . how many btu does it take to heat 15lb of water from 100 degrees F to 129 degrees F?

How many BTU's does it take to evaporate one pound of water?
BTUs to Evaporate One Pound of WaterQuick Answer: Somewhere around 1000BTU/lb Long answer: It depends on the temperature of the water you start with. Before you can evaporate the water, you must heat it to it's boiling point. The warmer the water you start with the fewer BTUs will be needed to heat the water to its boiling point. Keep in mind the BTUs require to raise the water to its boiling point are very few compared to the BTUs required to change the water from a liquid to a gas.One pound of steam contains 1150 BTUs. This is the energy you need to put into the water for it to evaporate if you start with water at 32F. If you start with water at 100F the water already has 70 BTU/lb so the BTUs required to evaporate the water when you start at 100F is 1150-70 = 1080 BTU and so on.You can get all this information in a steam table which can be found easily by searching the web.
How many btu to heat 1600 sf?
On average it takes about 1,600 BTUs to heat 50 square feet. Multiplying 50 by 1600 equals about 80,000. Therefore, the heating plan of 1,600 square foot are would take about 80,000 BTUs.
What is BTU of gasoline in engine?
BTU is an abbreviation for British Thermal Unit. This represents how much heat or energy is required to increase the temperature of 1 lb of water by 1 degree Fahrenheit. Gasoline, on average, creates between 115,000 and 125,000 BTUs. In contrast, ethanol creates about 75,000 BTUs.
What is the difference between a condensing central heating boiler and a combination boiler?
A combination boiler can use one of two different fuels to heat the water. Common combinations include natural gas/propane and oil, or wood and oil combinations. A condensing boiler uses a secondary heat exchanger to condense water vapour (steam) in the products of combustion down to water. Here's what that means: When any hydrocarbon (gas, propane, oil, even wood) burns, it gives off at least two "products of combustion. The carbon combines with oxygen to create CO2, carbon dioxide. The hydrogen combines with oxygen to create water vapour, or steam. (If combustion is "incomplete," there will be other trace products as well.) It's the water vapour or steam we're concerned with here. To boil 1 pound of water requires 960 BTUs of heat. Conversely, if you condense steam down into 1 pound of water, you will recover 960 BTUs. The fuel is burned in the "primary heat exchanger," where of course it releases a tremendous amount of heat into the water we're warming up. Then the "products of combustion" are drawn by a fan into the "secondary heat exchanger." When the water vapour or steam component of the products of combustion hits the relatively cool walls of this second heat exchanger, they condense down into liquid water. As they do, they release heat into the boiler water through the walls of the secondary exchanger. The liquid water then goes down a drain. Obviously, the boiler water has to be cooler than the steam component of the products of combustion in order for the heat to travel into it. So we make sure that this water is what's coming back to the boiler from the heating system. Again, for this method to work well, it's best applied in a "radiant in-floor" type heating system, where we don't heat the boiler water up to as high a temperature in the first place. --The HVAC Veteran
Is it better to have more btu's or less?
Whether it's better to have more or fewer BTUs (British Thermal Units) depends on the specific application. In heating or cooling systems, more BTUs typically mean greater capacity to heat or cool a space effectively. However, too many BTUs can lead to inefficient operation, frequent cycling, and discomfort. It's essential to choose the right BTU output for the size and needs of the space to ensure optimal performance and efficiency.
How many btus are needed to heat one lb of water one hundred degrees?
100 BTU if it's Fahrenheit
How many btu needed to heat 625 sq feet?
btus needed to heat & cool 625sf room
Is it the same BTUs to cool a house as it is to heat a house?
No, the amount of BTUs needed to cool a house is different from heating it. Cooling typically requires fewer BTUs because it involves removing heat from the indoors to maintain a lower temperature, while heating involves adding heat to raise the temperature.
How many btus does it take to heat up one gallon of water?
That depends on what the starting temperature of the water is,and what temperature you want it to reach.If you expect to get a number, you must first give the necessary numbers.
How many btus are needed to heat a sixty square foot room?
The number of BTUs needed to heat a room can vary based on factors like insulation, ceiling height, climate, etc. As a rough estimate, you can use the formula: 20 BTUs per square foot for a room with standard ceiling height. Therefore, for a 60 square foot room, you would need around 1,200 BTUs to heat it effectively.
How many BTUs is needed to heat to 70 degrees?
The number of BTUs needed to heat a space to 70 degrees will depend on factors such as the size of the space, insulation levels, outdoor temperature, and efficiency of the heating system. A general estimate is around 25-30 BTUs per square foot. It is recommended to consult a heating professional for a more accurate calculation.
How many btu's would it take to heat 120 gallons of water to 210 degrees f in 2 hours?
To calculate the BTUs required to heat 120 gallons of water to 210°F, first determine the temperature rise needed. Assuming the initial water temperature is around 60°F, you would need to raise it 150°F (210°F - 60°F). The BTU calculation is: [ \text{BTUs} = \text{gallons} \times \text{temperature rise} \times 8.34 ] So, [ \text{BTUs} = 120 \text{ gallons} \times 150°F \times 8.34 \approx 1,500,600 \text{ BTUs}. ] To heat this in 2 hours, you would need about 750,300 BTUs per hour.
How many btu's must be removed from 1lb of water at 200 degrees for it to end up as ice at 30 degrees?
There are no units for the temperature. The temperature change could be 230 Celsius degrees or 170 Fahrenheit degrees (94 Celsius degrees). In fact they could be in less commonly used units: eg Reaumur.
How many btus to heat water 10 degrees?
To raise the temperature of 1 pound of water by 1 degree Fahrenheit, it requires 1 BTU (British Thermal Unit). Therefore, to heat water by 10 degrees, it would require 10 BTUs per pound of water. This value may vary slightly depending on the specific heat capacity of the water.
How much heat is required to vapourize 5 pounds of water?
It takes approximately 970 BTUs to vaporize one pound of water. Therefore, for 5 pounds of water, it would require 4850 BTUs to vaporize all of it.

How many btu is needed to heat a 600 sqft room?
The amount of BTUs needed to heat a room depends on various factors such as insulation, ceiling height, climate, and desired temperature. As a rough estimate, for a moderately insulated room with an 8-foot ceiling in a cold climate, you would need around 20-25 BTUs per square foot. So for a 600 sqft room, you would need approximately 12,000-15,000 BTUs to heat it effectively.
