An explanation of why I use an electric duct heater with my solar system

This one is an answer to a comment criticizing my use of an electric duct heater to replace my nat gas furnace to use the kilowatt credits I get when I produce more power than I use. The original video is linked at the end of this video. This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome. If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.
