Quote: On the solar, I'd love it if it could work! Just that everything I've read and everything I've been told was that it wouldn't run the heat all night long. Where @armorfirelady and I live, there are weeks on end when the temperatures don't come above 25 degrees. That means that the waterers need to be running heat 24 hours. And her work schedule is such that she isn't home for longer periods of time so the waterers have to be reliable.
I wish it was just weeks.............more like months & months of temps below freezing here
In addition, she feeds wet feed during the winter that is in another heated bowl.
Are you saying that we could run TWO- THREE 25 (or 50) watt appliances 24 hours all winter long on one battery?
Eta:
Since the temps are that low, the thermocube won't shut them off until the temperatures are well above freezing. And a thermocube isn't needed with the heated bowls as they have their own thermometer that shuts off like the thermocube.
I would think that I could easily do it with one battery. My automatic pop door while it doesn't take a lot of energy it is always *on* because it has to close and open. I don't shut it off. And it is ran on a small battery maybe 4 inches by 2 inches. (It fits in a plastic container that the Mr Clean white sponges come in)
And yes my heated dog bowls shut themselves off when the temps are above freezing. I would think that the sump pump would take more power.
And I agree the initial costs are the worse but in the long run it will save me $$ & when the power goes out I do not have to worry about flooding or frozen feed bowls
