This page explains how DIY Solar Water Heater researches, writes, checks and corrects its content.
Our purpose
We publish guides about DIY solar water heating for hands-on homeowners and hobbyists exploring DIY solar water heating. Our guides focus on explaining how DIY solar water heaters work, what materials and components must withstand, and the limits and risks of DIY systems.
How we research
- 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.
- We separate facts, estimates and opinion. Facts and figures link to their source; estimates state their assumptions; opinions are labeled as our view.
- Where a guide covers safety, we link to the official source rather than restating it as our own advice, and we place warnings where readers will see them.
What we do not do
- We do not claim to have tested or used a product unless the article explicitly describes that use.
- We do not invent test results, scores, star ratings, statistics, testimonials or reviews.
- We do not promise savings, output, payback periods or performance that a source does not support.
- We do not publish hand-typed prices or “deal” claims, because they go out of date quickly.
- We do not accept payment, free products in exchange for coverage, or sponsored placements in our guides.
Safety-sensitive topics
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.
Affiliate links
We earn commissions from some links, as explained in our Affiliate Disclosure. Commissions never decide which products we include or how we describe them, and articles with affiliate links say so before the first link.
Updates and corrections
We review guides when products, specifications, rules or official guidance change, and we show the date a guide was last updated. If you find an error, please contact us with the page URL and details. We review every correction request, fix confirmed errors and note significant corrections at the end of the article.
