— Longevity — Low Maintenance — High Tur ndown — Advanced Controls In 1949, AERCO’s founder, Henry Angelery, had an idea for a water heater that offered accurate temperature control without storage tanks. From this idea, he designed and manufactured the world’s first compact, tankless water heater–paving the way for the thousands of semi-instantaneous and instantaneous heating units that are available today. Although a wide variety of various products and technologies have emerged over the ensuing 50+ years, none rival the performance, ease of ownership and durability of the WaterWizard™ heater....

Efficiency — Subcooling — Self-Descaling — Precise Temperature Control — Reliability — Longevity — Low Maintenance Efficiency — Subcooling — Self-Descaling — Precise Temperature Control — Reliability THEORY OF OPERATION The WaterWizard heat exchanger consists of a vertical stack of individual free-floating, helically-shaped coils–each of which is attached to both a steam riser and condensate return. Water flows from the bottom to the top of the unit and is heated as it passes over the coils in a counterflow design. As the steam enters each coil, it circles within three channels to its center...

— Longevity — Low Maintenance — High Tur ndown — Advanced Controls Because accurate temperature control depends upon carefully modulating steam input, even the best control systems will be of little value if coupled with an unresponsive control valve. So rather than rely on an off-the-shelf, generic valve that may fail to close tightly due to premature seat wear, the WaterWizard heater incorporates a proprietary valve designed by AERCO and performance-proven since 1982. A pilot assembly in the valve body ensures that a small inner seat is the only component that must be actuated to regulate the...

Key features of this innovative design deliver distinct advantages versus conventional U-tube and plate-and-frame-style heat exchangers. • Extensive surface...

— Longevity — Low Maintenance — High Tur ndown — Advanced Controls Individually replaceable and fabricated from .049" (1.25 mm) wall copper tube, the free-flowing manifolded design of the heat exchanger coils increases steam-flow capacity and improves heat transfer significantly. ASME-rated to no less than 250 psi (17 BAR) working pressure at 400°F (204°C) and condensate risers made from schedule 80 red brass pipe are strong, corrosion resistant and long-lasting bronze heads are considered the most durable, corrosion-resistant and reliable material available for potable water applications eliminates...

ACCURATE TEMPERATURE CONTROL Precise temperature control delivers more than just comfort and peace of mind–it helps reduce operating and maintenance costs across the overall system. By tightly controlling outlet temperature, the set point can be lowered to the absolute acceptable minimum with no extra cushioning to compensate for swings. A lower set point will reduce the amount of steam required as well as reduce piping-system radiation losses that would have had to be removed (at extra cost) by the air conditioning system. • Integrated load-monitoring system and patented steam valve deliver...

— Longevity — Low Maintenance — High Tur ndown — Advanced Controls More than simply an add-on actuator and PID controller, the fully integrated design of the electronic controls package incorporates a combination flow meter/inlet temperature sensor, inlet-steam vacuum/pressure gauge at the heat exchanger, feedback sensor, outlet temperature indicator and safety system. Together, these components work in concert to maximize the superior performance and control of AERCO’s patented valve. • Easy, one-touch start-up–just “set and go” • Dial-in operating set point and digitally tune system parameters...
