British thermal unit The British thermal unit (BTU or Btu) is a traditional unit of work equal to about 1055 joules. It is the amount of work needed to raise the temperature of one pound of water by one degree Fahrenheit (Physical analogue: one four-inch wooden kitchen match consumed completely generates approximately 1 BTU).efinitions of the BTU based on different water temperatures can therefore vary by up to 0.5%. A BTU can be approximated as the heat produced by burning a single wooden kitchen match or as the amount of energy it takes to lift a one-pound weight 778 feet (237 m).

- BTUs. BTU is the internationally used and accepted measurement for heating capacity. Technically, 1 BTU equals the amount of heat required to raise the temperature of 1 pound of water by 1 degree Fahrenheit. The BTU capacity is listed on the labeling for the stove in stores and in the owner's manual for stoves and ranges.

In the heating and air conditioning industry the measure of heat that heating fuels and appliances produce is referred to as a BTU (British Thermal Unit). Below you will find information in reference to BTUs. Having appliances or furnance that are rated at a BTU output too low for your house type and size can mean that your appliances my have to run 2-3 times as much as a larger output appliance or furnace would to acheive the same result. Always consult a professional when choosing a heating or cooking fuel and appliance.

- BTU stands for 'British Thermal Unit' and is a measurement of energy. One BTU is approximately the amount of energy required to heat one pound of water by 1° Fahrenheit - about the same amount of energy produced by a single 4-inch kitchen match that's been burned from one end to the other. BTU’s are commonly used to measure and compare the heat output of different hot water radiators.

The Average BTU of Furnaces Average BTU Ratings. A typical furnace is rated at 100,000 or 80,000 BTU per hour, but furnaces might be as small as 40,000 or as large as more than 200,000 BTU. A 90 percent high-efficiency rated at 60,000 BTU will deliver about 54,000 BTUs per hour of heat energy to your home.However, many other factors change this efficiency, which is why the Manual J Load rating is used. 90 percent high-efficiency rated at 60,000 BTU will deliver about 54,000 BTUs per hour of heat energy to your home.

- One Btu is defined as the amount of heat required to raise one pound of liquid water one degree Fahrenheit, specifically from a temperature of 59 degrees to 60 degrees. The energy content of a fuel is typically given in Btus per pound of fuel. Fuel oil, for example, has an energy content of roughly 18,500 Btu/lb. For gaseous fuels, such as natural gas or propane, energy con-tent is also expressed in Btus per cubic foot (Btu/ft 3).

The Average BTU of Furnaces When choosing a furnace, the BTU rating helps estimate how much heat energy it will require to heat your home. However, there isn’t an average BTU for all furnace sizes, because there are several variables that influence the overall BTU rating and efficiency. 90 percent high-efficiency rated at 60,000 BTU will deliver about 54,000 BTUs per hour of heat energy to your home. However, many other factors change this efficiency, which is why the Manual J Load rating is used.

Air Conditioner Basics An air conditioner’s SEER rating is its total cooling output in BTU during a “normal” annual cooling season divided by the unit’s total energy input in watt-hours. The EER (energy efficiency ratio) is a similar rating that is based on the unit’s performance during peak conditions (typically 95°F).
