I am trying to find an HVAC unit that is no more then 14" in height; I also need to be able to set it at a specific temp. as it will going into a room housing tropical birds The old contractor did not do the duct system properly for the HVAC system on my new house - the suppliers and returns are not enough and not balanced, and thus caused a lot of issues. Actually, the old contractor did all 4 houses wrong, all with the similar issues, in a row in my community.

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. See similar questions...

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: See similar questions...

Gallons Per Minute is the volume in gallons of the slurry pumped per minute. GPM can be used independent of pipeline size to calculate production. Examples of flow rates are 4,200 GPM for 10" pump up through 56,500 GPM for a 30" pump. See similar questions...

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 See similar questions...

Gallon Per Minute determines the rotational speed of the tong. A low GPM will cause the tong to operate at a lower speed with a lower RPM while a high GPM will cause the tong to operate at a higer speed with a high RPM. Eckel offers an RPM Control which is a flow divider to decreatse the amount ofhydraulic fluid that reaches the tong, the remaining fluid is returned to the reservoir. See similar questions...

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. See similar questions...

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. See similar questions...

The overall value of a pressure washer is decided by two factors, pressure and amount of flow. Most people only consider pressure and disregard the equally important flow of the unit. Pressure is measured in pounds per square inch (PSI). This determines how much power the unit has to clean surfaces and break the bonds of dirt and debris. Water volume, also known as the flow of the unit, is measured in gallons per minute (GPM). See similar questions...
