QuickDraw® Semi-Instantaneous
- a SUPERTANK® Water Heater

Available with AquaPLEX Duplex Alloy

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. Electronic operating control with Modbus capability.


  • Eight standard sizes from ~ 8 to ~ 110 gpm 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).

Steam Control

    valve with solenoid actuator.
  • Optional controls include two-position steam valves with
    electric or pneumatic pilots and modulating valves with
    pneumatic pilots.
