Denny, I know my heater isn't perfect, but it's a darn sight better than no heater at all. Some folks might want perfection (like you seem to from your description), but some folks just want a working heater. As you can see from this lengthy thread, they're not that easy to come by. But your argument has always been that there should be enough demand to make manufacturing them profitable. If that were true, my flawed heater should have sold quite easily. So, I think the likelihood is high that the demand isn't nearly as great as you think it is.
