So the difference in cost between natural gas and ElectricAir is ~ 400/yr. And it costs $14,000 to install the ElectricAir system. It will take a very long time to break even. It will be very difficult to convince people with current working natural gas system to switch over.

Sure but his target market is North America, where I don't think there is too much danger of dropping fossil fuel heating anytime soon.
