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. See similar questions...

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...

BTU's (British Thermal Units) are a standard of measurement which represent the heat value of any type of energy used to create heat. The amount of fuel that a fireplace will consume per hour is calculated with the BTU value of the fuel it uses to determine the input of that fireplace. BTU values of any type of energy are determined by the actual amount of heat required to increase the temperature of one pound of water, by one degree Fahrenheit. See similar questions...

To have a US item run under UK current you need to buy a transformer, a product that you plug into the wall and has a US-style jack at the other end. The transformer will "step down" in voltage from 240 to 120v. From there you may want to plug in a US-style power strip and provide current for sev eral products. Next you need to consider how many watts your transformer is providing (all transformers should clearly indicate this). See similar questions...
