Guide explaining hot‑water wait problems and detailing selection, installation and operation of Taco domestic recirculation systems.
Waiting for hot water wastes water and energy. Taco’s Domestic Hot Water Recirculation (DHWR) systems eliminate the wait, providing instant hot water while conserving resources. The guide describes the problem, the energy impact, and the benefits of installing a Taco DHWR product.
The guide covers system types—dedicated return line (Plumb N'Plug®, SmartPlus™, TacoGenie®) and non‑return line (Hot‑Link®, Hot‑LinkPlus™, TacoGenie®)—and provides typical piping layouts, pump selection charts, submittal data, and installation instructions for new or retrofit applications.

The Hot‑Link valve uses thermal‑disk technology to send cooled water back to the water heater, creating a recirculation loop without a dedicated return pipe.
