Rinnai is the number-one selling brand of tankless gas water heaters in North America. They are an engineering-driven company with decades of experience developing the on-demand water heating technology that has made waiting for hot water an outdated experience for millions of homeowners across Salt Lake City, UT and beyond. As part of their commitment to delivering hot water faster, more efficiently, and with less waste, Rinnai has built a comprehensive recirculation ecosystem directly into their residential tankless lineup. This is a system that eliminates the frustration of waiting at the faucet for hot water to arrive while simultaneously reducing the water and energy waste that conventional wait-and-run hot water delivery produces in homes every day.
Rinnai’s recirculation ecosystem is designed to work across different home configurations including homes without a dedicated hot water return line, which have traditionally been incompatible with recirculation systems. Optional accessories including the RWM200 Wi-Fi Wireless Module, RPB200 Push Button, and Rinnai Central™ mobile app extend recirculation control to smartphone scheduling and on-demand activation for homeowners who want additional flexibility beyond the Smart-Circ™ learning schedule.
Hot water that arrives at the faucet within seconds – not after 30, 60, or 90 seconds of running the tap. This is one of the most practical comfort upgrades available to homeowners across Salt Lake City, UT, and Black Diamond Experts is your trusted licensed plumbing contractor for Rinnai recirculation system installation, service, and optimization. Our plumbers are trained on the full Rinnai recirculation ecosystem.

Rinnai’s integrated recirculation solution — tankless water heaters with built-in pumps and Smart-Circ™ Intelligent Recirculation™ that learns your household’s hot water schedule.
Rinnai’s built-in pump tankless water heater models are the most integrated recirculation solution available, combining a high-efficiency tankless water heater and a recirculation pump in a single unit, eliminating the need for a separate external pump installation. The RXP Series extends built-in pump recirculation to Rinnai’s premium condensing tier, delivering hot water to up to six locations around your home. The RE Series also features a built-in pump with Smart-Circ™. This feature observes hot water usage over a rolling seven-day period and builds an automated recirculation schedule accordingly. All built-in pump models are compatible with optional accessories for Wi-Fi control and on-demand operation.
Hot water recirculation without a dedicated return line — Rinnai’s thermal bypass valve technology for homes that weren’t originally plumbed for recirculation.
The conventional assumption about hot water recirculation is that it requires a dedicated hot water return line running from the farthest fixture back to the water heater. This has historically excluded the majority of homes from recirculation upgrades, since most residential construction does not include a dedicated return line. Rinnai’s thermal bypass valve approach directly addresses this limitation. This approach makes recirculation available in virtually any Salt Lake City, UT area home, regardless of original plumbing design.
Expand and customize your Rinnai recirculation system — Wi-Fi connectivity, push-button on-demand activation, and the Rinnai Central™ app for complete remote control.
Rinnai’s recirculation accessory lineup extends the capability of Smart-Circ™ beyond its built-in seven-day learning schedule. This feature adds on-demand activation, Wi-Fi remote control, and smartphone scheduling for homeowners who want complete flexibility over when and how their recirculation system operates. Together, these accessories give homeowners multiple levels of control over their Rinnai recirculation system depending on how much automation and connectivity they want from their hot water delivery.
