Other Recirculation
SOLUTIONS
Rinnai recirculation solutions build on the already endless supply of hot water Rinnai
Tankless Water Heaters provide—adding the convenience of faster hot water.
Rinnai Circ-Logic technology comes standard on all Luxury models, and can be
used in combination with the following accessories to allow homeowners to set
recirculation patterns that coincide with their hot water usage patterns. Hot water is
available when needed, without the expense of circulating it during times of inactivity.
SOLUTION 1: GTK15 PUMP AND TIMER KIT
Allows homeowners to schedule multiple recirculation events throughout the day to align with usage
patterns, such as getting ready in the morning.
SOLUTION 2: MC-195T 24-HOUR DIGITAL CONTROLLER AND PUMP
A stylish, wall-mountable digital control panel works seamlessly with Rinnai Circ-Logic technology and
any properly sized pump. Multiple unique recirculation events can be programmed as well as an override
function for homeowners to start recirculation outside of scheduled events.
SOLUTION 3: RINNAI CIRC-LOGIC AND PUMP
For recirculation without scheduled events, simply pair a Circ-Logic equipped tankless model with a properly
sized pump. Recirculation intervals can be set to Comfort mode (shorter time intervals) or Economy mode
(longer time intervals). Recirculation deactivates once the water has reached set temperature.
