Function
The Caleffi TankMixer ™ 520_AX series kit combines a three-way
thermostatic mixing valve with a cold water tee and flexible pipe for
easy installation directly on a typical gas-fired water heater and other
water heaters that now comply with the National Appliance Energy
Conservation Act (NAECA). The TankMixer ™ maintains the desired
output temperature of the mixed water supplied at a constant set
value compensating for both temperature and pressure fluctuations
of the incoming hot and cold water. The mixing valve also features a
thermal shut-off function that operates in the event of a cold water
supply failure at the inlet. Also available as body only, for a wide
variety of separately-sourced end connections, the angle style body
design offers improved fluid dynamics for better performance and
reduces installation labor and materials, eliminating a piping elbow
in typical installations.
