EER ignores "units" to come up wth a marketing number that looks good (13), But that is 13 times more BTU's than WATTS in. So to understand true energy, you have to convert them to the same units (divide by 3.42 BTU/W) and so the actual conversion is 13/3.42 or about 3.8. Still much better than direct (resistance) conversion, but not 13 to 1. Bob, WB4APR -------------- next part -------------- An HTML attachment was scrubbed...
