BTU stands for British Thermal Unit. It is the industry standard unit of measurement for heat quantity. 1 BTU is the amount of heat required to raise the temperature of one pound of water at its maximum density by 1 degree Fahrenheit:

A British Thermal Unit is the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit.

British Thermal Unit. It measures the quantity of heat required to raise the temperature of one pound of water one degree Fahrenheit at sea level. BTUs are the primary measurement used to match your cooling

Btu - One British thermal unit (Btu) is the heat required to raise the temperature of one pound of water by one degree Fahrenheit. Mcf - Mcf is the volume of one thousand cubic feet of natural gas and equals 1.031 million Btu on average. Natural gas can be measured based on its volume (cubic feet or Mcf) or based on its heat content (British thermal units or therms). Prices can be converted from one basis to another by using the relative ratio of the corresponding heat or volume measure.

Because the waste is a fuel and some facilities have permit limitations or tighter operational constraints on Higher Heating Value of waste. The BTU value determines how waste is processed.

BTUs, or British Thermal Units, indicate the volume of gas a grill can produce. BTUs do not refer to cooking power, as many believe. As the number of BTUs increases, so does the amount of fuel that is used. Too many BTUs can damage the grill's burners. In general, grills with larger cooking surfaces require a higher number of BTUs.

Greenhouse insulation surprises people, but.... A modern greenhouse in good condition can achieve average insulation but the majority of others can only be classed as poor. Surrounding walls are only a problem if they contain combustable materials (e.g. wood or drywall) or material that would melt (e.g. porch screening).

To calculate maximum BTU / Hour, multiply the input power rating in watts on the rear panel of the unit (or on the external power supply, [i.e RS 1]) by 3.41. Example: RPM 88 is rated at 55 watts AC, therefore we expect a maximum of 187.55 BTU / Hour.

A typical gallon of waste oil contains 153,000 to 180,000 BTU per gallon, which can be almost TWO TIMES the energy potential per gallon of LP gas. LP gas has a potential for 92,000 BTU per gallon.

BTU for inside the home, or a controlled environment. The upgraded 2500 for warmer climates and warmer situations. Unit must be vented properly.
