Rinnai/Grundfos Pump and Timer Kit, Flange Kit

Use this Grundfos GTK15 Pump Kit to run the recirculation system with Rinnai Tankless Water Heaters with Rinnai Circ-Logic™ including RUR98eN, RUR98eP, RUR98iN and RUR98iP. It allows you to get a instant hot water at distant points of use on a preset schedule. Scheduling the times of use saves money by reducing wasted energy during times when hot water is not needed.

The integrated timer on the GTK15 is not compatible with any of the Rinnai Sensei models (RU130, RU160, RU180, RU199, RUR160, RUR199, CU160, CU199, M120CN, M160CN, M090CN, M060CN, M160SN, M120SN, M090SN, M060SN). If you wish to use the GTK15 with a non-Sensei Rinnai unit, including Ultra/Luxury series models, please refer to this technical bulletin. The Grundfos pump for the SENSEI units is the GTK03. You can purchase the GTK03 in multiple different kits that come with controllers to set timers for the recirculation pump.
