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
What is the tonnage of a 108000 btu ac?
A ton of refrigeration is defined as the amount of heat removal required to change one ton of water (2000 pounds) at 32 degrees F to one ton of ice at 32 degrees F in one day which is 288000 BTUs. Today it is assumed that BTU ratings are by the hour, so one ton of refrigeration is the removal of 1200 BTU/hr. So if your air conditioning unit is removing 108000 BTUs/hr it is a 108000/12000 or 9 ton machine.

Why heat is needed to boil water?
Because heat changes the temperature of the water
How many btus to heat a city?
The answer depends on the city. Somewhere like Colombo (Sri Lanka) will probably require 0 btus.
How many BTUs will it take to change 1 gallon of water at 32 degrees to ice at 32 degrees?
You would need to remove approximately 1200 BTUs of heat to convert a gallon of water to ice. There are 8.34 lb in a gallon of water, which converting to lb-moles is 0.463. The latent heat of crystallization for water is -2583.4 BTU/lb-mole. Multiplying the two together and you get -1197 BTUs, which means you need to remove that amount of heat to convert the gallon of water to ice.
How many square feet will 26000 btus heat?
how many square feet will 26,000.00 heat
How many BTUs to heat a 500 square foot house?
about 12,000
What is 650 degrees in BTUs?
One measure does not directly translate to another. A BTU is the amount of heat that it takes to raise the temp of one pound of water by one degree F. A burning match, and a burning fireplace may both be at 650 degrees, but the fireplace gives off more heat (more BTUs)
