But anyone with a brain isn't interested in the heat that's wasted. We're interested in how much cooling we get compared to how much electricity is used. With the old system Stormin was talking about, we might get 40,000BTUs/hr using $1 of electricity. Replace it with a newer, higher efficiency system, and we get 40,000BTU/hr using only $.70 The new system is more efficient at producing cooling. Capiche?
(As it is in an absorption system too)
Coefficient of Performance is one measure of efficiency. In fact the word "coefficient" is derived from the root "efficient. Have you Googled SEER, as requested? What is the third word? EFFICIENCY
