    Ideas for heat using car battery and timer to go on at night

    Boat trailer lights may be sealed when there made but there not by the time they make it to the water. I have never seen one that didn't pour water out of the lights when it came out of the water. Mine has never busted when I backed down in to the water an my housings are busted. Those bulbs...

    Ideas for heat using car battery and timer to go on at night

    Low voltage direct current like what comes out of a battery is safe. Every time you back a boat trailer in the water you sink the tail lights under water. Filling the light socket with silicone or a edible grease might help keep corrosion down. High voltage alternating current (house power) is...

    Ideas for heat using car battery and timer to go on at night

    I didn't say ya need all that insulation. If ya had perfect insulation then one watt would eventually boil the water. But if ya had at least good insulation (plastic coated foam waterier with just an open drinking hole) then it would only take about 1.75 watts for every cubic foot at -20* to...

    Ideas for heat using car battery and timer to go on at night

    I know for a fact (by testing it) that a 5 watt bulb will raise the temp of a one foot cube of liquid medium by well over 50*F. At -20*F that would bring it up to 30*F+. Never tested it past 50* of heat but I would guess it would get to around 70* of added heat. So if I had to guess it would...

    Ideas for heat using car battery and timer to go on at night

    Over not in.... A bulb turns electricity in to 3 things. About 90% (conduction)heat energy that floats up away from your waterier by convection, about 5% light energy that does nothing for you an about 5% (if that) radiant heat energy. Assuming you can get all of that radiant heat to hit the...

    Ideas for heat using car battery and timer to go on at night

    i agree that heat is not needed but some people want to. To me (if you chose to add heat) adding heat under the bird where it rises up threw the bird makes more sense. Fact is no matter how insulated your coop is if you have enough ventilation then your heat floats away. If you add the heat...

    Ideas for heat using car battery and timer to go on at night

    Why heat the whole coop. Use a flashlight bulb dropped on the waterier to keep it from freezing up. They run on 12V an pull less than a watt. Then make your roosts out of metal pipe an circulate heated air threw them. Ya only need a PC fan, a house thermostat, a 1157 taillight bulb an a box to...
