B. HOW THE HEATER OPERATES
Modulation Condensing Technology is an intelligent system that delivers
highly efficient water heating, while maximizing efficiency by measuring the
data parameters of your water heating system. Some of its features are:
Stainless Steel Water Storage Tank
The stainless steel water storage tank has a combustion chamber
submerged into the tank water. When the water heater is fired, combustion
gases heat the combustion chamber walls, transferring heat directly into the surrounding water. These hot gases are blown into
secondary heat exchanger coils, where more heat is transferred into the water, removing even more heat from the gases.
