Among model aircraft hobbyists, the ducted fan is popular with builders of high-performance radio controlled model aircraft . Internal-combustion glow engines combined with ducted-fan units were the first achievable means of modeling a scaled-size jet aircraft. Despite the introduction of model-scale turbojet engines, electric-powered ducted fans remain popular on smaller, lower-cost model aircraft. Some electric-powered ducted fan airplanes can reach speeds of more than 320km/h (200mph).
See my other post http:///b/projects/make-the-switch-to-electric-space-heating/ for information on how to determine which method of heating will be least expensive. Good luck.
