Bock ElectriTHERM Swing Tank Plus Water Heater

Swing Tank Plus

• Designed for use in Commercial Heat Pump Water Heating Systems as a Swing Tank for Single-Pass or Multi-Pass Heat Pump Systems
• PLUS - a means to augment energy input for multi-pass heat pumps when ambient temperature < 40°F or as an emergency backup unit.
• Step modulation between three inputs – Min, Mid, or Max
  • At call-for-heat, the initial input is based on (supplied)outdoor temperature sensor reading(≥40°F = Min; <40°Fand ≥24°F = Mid; <24°F = Max)
  • Attempts to recover tank temperature at lowest electric resistance input
  • Additional input added if sensor continues to drop from setpoint
• Two configurations available
  • 12.1/24/36kW
  • 18/36/49.5kW
