How the Water Heater Operates

Condensing technology intelligently delivers water heating while 

maximizing efficiency. Outlined below are the features of the system 

and how they operate:

Stainless Steel Heat Exchanger -

 The highly efficient 316L stainless 

steel fire tube heat exchanger with internal aluminum is designed 

to extract all available heat from the combustion process and pass 

it into heat transfer fluid. The stainless steel construction provides 

protection for longer service life. The heat exchanger offers greater 

water content, providing lower system pressure and greater overall 

system efficiency.

10 to 1 Modulating Combustion System -

 The combustion 

system is specially designed to provide very high turn down. This 

combustion system will modulate the burner output to very low 

levels to match the system demand and achieve better overall control 

of the heating system for maximum efficiency and reliability.

Control – 

The integrated control system monitors the system and 

responds to internal and external signals to regulate fan speed and 

control output. This allows the water heater to deliver only the amount 

of hot water required and nothing more.

The control can regulate the output of multiple water heaters through 

its cascade system function by establishing one water heater as the 

master and the other connected water heaters as followers. The 

master water heater requires a sensor to provide feedback on set point 

temperature in order to adjust heating output from the connected 

water heaters. Multiple water heater cascaded systems offer greater 

system turndown and redundancy.
