Vaughn is a Massachusetts-based premium stainless water heater manufacturer with a specific specialty: stainless steel tanks for solar thermal storage, indirect heating, and premium electric applications. Vaughn doesn\'t compete in volume residential — their products are spec-grade for solar installations, custom indirect setups, and premium owner builds.
The Vaughn water heater lineup
When Vaughn is the right brand
- Solar thermal storage — pairing with Heliodyne, SunEarth, or other collector brand
- Custom indirect setup — where Triangle Tube Smart or Lochinvar SQUIRE doesn\'t fit specifications
- Premium electric tank in aggressive water — alternative to Marathon composite or Westinghouse stainless
- Made-in-USA preference with custom-spec capability
Solar storage applications
Solar thermal systems need storage tanks that can withstand:
- Higher peak temperatures than standard tanks (sometimes 180°F+)
- Glycol-side fluid in the heat exchanger coil
- Thermal cycling as solar input varies daily
Vaughn solar storage tanks use stainless construction and single-coil heat exchanger specifically engineered for these conditions. 15-year tank warranty on solar storage applications.
