  12. In article (Doug Bliss) writes:
  13. >I have heard that oil-fired domestic hot water heaters are very ineffecient (
  14. >20-30% efficiency) compared to electric hot water heaters.  
  15.  
  16. But remember that electricty is often generated from oil/natural gas/coal
  17. at less than 40% effeciency.  If you want to compare efficiency you must
  18. take this fuel-power conversion efficiency into account.
