Shortlist smarter with these quick checkpoints.
We benchmark specs, energy use (where relevant), and long-term ownership reviews from Indian shoppers. Only products with consistent performance over six months make the Top 5.
No. Amazon links help keep TechKath Reviews free, but we never accept paid placements. Picks may change when better products launch.
We monitor price drops and availability weekly, then run a full qualitative refresh once per month or when a new flagship releases.
Editorial depth
water heaters buyers in India typically compare five or more models before hitting “add to cart,” so each TechKath Reviews guide exceeds 900 words, includes photos, and links to supporting explainers. That level of detail helps Google rank us for “best water heaters in India” or “top 5 water heaters 2025” without keyword stuffing.
We triangulate data from BIS certificates, service-center SLAs, and Amazon verified-purchase feedback. If a product gets a firmware update or a new batch with downgraded parts, the list is re-run before the next AdSense review cycle.
To stay compliant with AdSense and Amazon Associates, affiliate CTAs are labeled clearly, ads never overlap with buttons, and every section links back to our Privacy Policy and Affiliate Disclosure. That makes monetization obvious to readers and policy reviewers alike.
