QuickDraw® Steam Semi-instantaneous
QuickDraw semi-instantaneous heaters combine a relatively large single or double-wall copper u-tube bundle with a small vertical tank to provide moderate to large amounts of domestic water while occupying less floor space.
Now available with electronic operating control that is Modbus connectable to BAS.
Available with AquaPLEX®, a fully passivated, high-chromium duplex material that requires no lining. Naturally impervious to water corrosion and provides superior resistance to chloride stress corrosion cracking compared to 316L stainless steel. ASME approved material.

Eight standard sizes from ~ 8 to ~ 110 gph of water at a 100 degree rise with 15 psi steam entering the valve.
Custom sizes available with the only limitation being the available sizes of u-tube exchangers and steam valves.
Vertical orientation: Approximately 50 to 100 gallons depending upon model. (with a semi-instantaneous water heater, storage is a minor consideration compared to recovery capacity).
Standard control is a self-contained, two-position (on-off), pilot-driven steam valve with solenoid actuator.
Optional controls include on-off steam valves with electric or pneumatic pilots and modulating valves with pneumatic pilots.
ETL listed as a packaged water heater.
ASME, section IV, part HLW stamped and National Board Registered.
Control panel is ETL panel shop approved.
