N1103.5.1 (R403.5.1) Heated Water Circulation and Temperature Maintenance Systems (Mandatory)

Residential Code 2018 of Kansas > 11 [RE] Energy Efficiency > N1103 (R403) Systems > N1103.5 (R403.5) Service Hot Water Systems > N1103.5.1 (R403.5.1) Heated Water Circulation and Temperature Maintenance Systems (Mandatory)
JUMP TO FULL CODE CHAPTER
Heated water circulation systems shall be in accordance with Section N1103.5.1.1. Heat trace temperature maintenance systems shall be in accordance with Section N1103.5.1.2. Automatic controls, temperature sensors and pumps shall be accessible. Manual controls shall be readily accessible.

N1103.5.1.1 (R403.5.1.1) Circulation Systems

Heated water circulation systems shall be provided with a circulation pump. The system return pipe shall be a dedicated return pipe or a cold water supply pipe. Gravity and thermosyphon circulation systems shall be prohibited. Controls for circulating hot water system pumps shall start the pump based on the identification of a demand for hot water within the occupancy. The controls shall automatically turn off the pump when the water in the circulation loop is at the desired temperature and when there is no demand for hot water.

N1103.5.1.2 (R403.5.1.2) Heat Trace Systems

Electric heat trace systems shall comply with IEEE 515.1 or UL 515. Controls for such systems shall automatically adjust the energy input to the heat tracing to maintain the desired water temperature in the piping in accordance with the times when heated water is used in the occupancy.
