DIY Solar Water Heater is an independent website about DIY solar water heating. We publish guides for hands-on homeowners and hobbyists exploring DIY solar water heating, with a focus on explaining how DIY solar water heaters work, what materials and components must withstand, and the limits and risks of DIY systems.
Who we are
DIY Solar Water Heater was founded in 2026 and is run by a small, independent editorial team. We are an online-only publication. We are not owned by, and do not work on behalf of, any manufacturer, installer, brand or retailer, and no company reviews or approves our guides before they are published.
What we cover
Our guides are organized into these sections: DIY Solar Water Heater Basics, DIY System Components, DIY Project Planning, DIY Designs, DIY Maintenance and Troubleshooting and DIY Solar Water Heater Safety. Each guide explains what matters for a given situation, which trade-offs to expect and where its advice stops.
How we research
Our content is written by the DIY Solar Water Heater editorial team. We base our guides on the U.S. Department of Energy, manufacturer specifications for components, published plumbing and safety guidance, and official public health resources on scald and water safety, and we link to the source when a guide states a figure or a safety point.
We are clear about the limits of our work. Unless an article explicitly describes our own use of a product, our guides are research-based and are not hands-on product tests. We do not invent test results, ratings or statistics. Read our Editorial Policy for details.
Safety and scope
Hot water can scald, heated water can build dangerous pressure, and stored lukewarm water can grow harmful bacteria. Our guides explain concepts, limits and safeguards; they are not a substitute for local plumbing codes, permits or a licensed plumber. Never remove or block a temperature and pressure relief device, and use only materials rated for drinking water where water may be consumed.
