Don’t worry if the cold weather is here. There is no need for electricity to warm up water when you have this device ready to go. The DIY Solar Water Heater is a project you can easily do yourself. The homemade `flat panel` copper coil solar water heater can reach temperatures well over 150 degrees Fahrenheit (65 °C). As far as materials go, you will need a 50-foot roll of tubing (which is much cheaper than smaller rolls connected to each other), standard window glass, and flat black paint. You can even store it in the closet when you’re not using it, because the slick design allows for this easily. Watch the entire video provided to learn how to make your own DIY solar water heater right away.

Well, not knowing your expertise with woodworking, suggest maybe putting something small along the sides, such as ‘screen stay’, you nail in place or you can use silicone to lay a bead down over that glass, along that indented edge..Hope you understand where I’m coming from. Good luck.
OK – what do you get? maybe a quart at a time? how long between HEATED tubes full of water?
how effective at say 20 deg or below zero temps with full sun?
will this work in really cold climate? like the UK or Canada?
these looks great how would it work in the winter in North Idaho when it gets below freezing
How can I adapt it to a water heater so it receives this hot water, instead of cold water, so I can save gas?
how can I use this in my barn without the piping freezing?
The only water that’s hot is the water in the coil for a while, which is very little. Don’t expect any water flowing through it to even be warm. Waste of time and money.
Good tutorial. Really clean, guided explanations with good correlating images. I’m not sure how much hot water you could get but it would sure enough be more than you’d get otherwise electricity free. Freeze could be an issue in winter on cloudy days and certainly in the eve’s after sundown. Repeated freezing would probably eventually blow the pipes – so there would be thoughts about that. Worry free use during summer though – quick hot shower, plenty of warm for dishes etc. I wonder if there’s any way to store the heat energy that wouldn’t be used. How about some kind of rooftop system with gravity as the water inflow. Yours is one of the best and clearest tutorials I’ve seen. Really well done. As far as off grid energy goes, I guess we’re all in the process of pondering on things and tryin them out.This is a good idea. Definitely functional with some limitations. Really good tutorial. Thankyou ?
