Solar Hot Water Collector,Free hot water,Doomsday Preppers This is an update to the video i made the 7 days ago to see if i could make the water get hotter.As you can see in this video just a little change i made a 6 degree difference in temperature.i am sure when summer comes i will have to put some screen wire over the top of the glass to keep it from getting to hot. This free hot water is really nice when the light bill comes in. the december light bill was 66.00 . I will be making some solar panels soon.    • Homemade Solar Hot Water Heater Update   .Solar water heating systems have a good economic payoff, and are manageable systems to install or build as a DIY project. Some of the solar water heating designs are very simple and low cost. You can save as much as by building your own system.This heater uses PVC instead of copper. PVC has a much lower thermal conductivity than PVC does, however there are a few ways to over come this weakness. One way to I increased the efficiency was to use old florescent light bulbs as sleeves over the PVC pipe to act as a double glazing. This helps insulate the PVC and increases the efficiency of the heater. I also insulated the PVC connections to help shield them from the intense heat of sunlight. The other way I increased efficient was increasing the surface area. Since PVC is cheap it did not cost much to run more pipes that would be exposed to the sun.I also installed an automatic electric backup heater for $30. It is a bucket heater that turns on at 80 degrees and off at 110. The collector is made from Coroplast which is a corrugated plastic sheet, commonly used for making signs. It has multiple square channels running lengthwise from end to end. When I first saw this type of sheet I immediately thought, “Wow, this would make an excellent flat panel solar collector if only there was a way to pipe water through all those little channels.” Several weeks later, a method of doing so occurred to me. If a slot of the right width is cut lengthwise in some ABS pipe (so the cross section looks like a “C”) then this pipe can be fit over the end of the corrugated plastic. The seams can be sealed to make everything water tight. The sheet can be painted black and voila… you have a flat panel solar collector.Because the whole collector is made of plastic, it is important that the temperature doesn’t get too high or it will soften and possibly spring a leak. 80 degrees C (176 degrees F) is about the limit. Don’t think it can get that hot? Think again. In practice the maximum temperature is difficult to guarantee. Water may stop circulating, or may drain out completely for a number of reasons and the panel will overheat. Therefore this may not be a practical design for residential installation but it is an inexpensive, easily built experimental system that produces as much or more hot water than commercially available systems. building homemade solar hot water heater collector free hot water homemade solar hot water pool water heater.
