Since electricity produces X amount of heat, when resisted Y, it never is more or less efficient. It's pure math.
The main attraction for me, in considering ceramic, in the future, would be safety, I think. I also am concerned about the future availability of bulbs generally. The red infrared bulbs also have a reasonably short life-span. It seems logical to assume that a ceramic emitter, while a bit pricey up front, would provide many seasons of heat? Those are my thoughts. That it produces no light is also a good thing, in my universe. We shall see
Fred, I am with your line of thinking. Every day I am thinking to myself...how much longer will all our luxuries (even the mill-bought chicken feed) be available for us.
The thought of these kinds of things has had my anxiety level up lately. Although we have acreage we are so very far from being self-suffincient.
As for the heat lamp, I like the red bulb because the babies do, but I wish I could get one around here less than 250 watts. It gets too hot sometimes, even jacked high up.
This is the first flock of my own and I am hoping to just let the broodies do the work of providing heat from here on in. (I have BO's and leghorns)
