Question

Is it the intent of 607.1.1 and 607.1.2 to require
temp. limiting device at the water heater (ASSE
1070) in residential occupancies such as
apartments four stories or more?

Answer Published 11/14/2016 at 9:07 AM

No. There is no requirement for ASSE 1070 devices
specifically on water heaters.

Commentary

This code section specifies that when tempered water is to be delivered to a tempered water system or to one or more fixtures it must be controlled by a device that complies with ASSE 1070. This would apply to non-residential occupancies for bathing or washing. Residential occupancies require that these fixtures be supplied with hot water. Hot water temperature limits are handled elsewhere in the code such as at Sections 613 and 424.3.
