2008 Pool Heater Energy Data        
What is "thermal efficiency"?  
Thermal efficiency (expressed as a percentage) is the measure of efficiency for pool heaters - the higher the percentage, the more efficient the model.  
       
What does "Input (BTU/Hr)" mean?  
Manufacturers size their pool heaters by the heat "input" rating which is measured in British Thermal Units (BTU's) per hour. This is a measurement of the heat value that the pool heater produces per hour.   
   
NOTE:  Data submitted to the Federal Trade Commission in May 2008.
