About Kings Peak
Professional grade tankless water heating, engineered for the modern American home.
Kings Peak designs, certifies, and supports high-efficiency tankless water heaters for residential and light commercial use. Our products are built around the realities of installation, service, and long-term ownership.
Our mission
Deliver tankless water heaters that homeowners can rely on for decades and that contractors can install, service, and stand behind.
Engineering focus
A copper heat exchanger in the non-condensing KNG199INW and a 304 stainless steel heat exchanger in the condensing KNG199ICW.
Product development
Every model is developed against real installation conditions across the American market (high water hardness, cold inlet temperatures and long developed gas lines), not just lab conditions.
Certifications
Certification details for each model are listed in its installation, use & care manual.
Support philosophy
Real technical support, by people who know the product. We answer the phone for contractors standing in front of a unit and we publish the diagnostic information they need.
Warranty commitment
Warranty terms are described in each model's manual. Proper installation and routine maintenance matter for coverage.
