Power VT® Plus - Condensing Water Heaters

Available with AquaPLEX Duplex Alloy

95% to 96% thermal efficiency at full firing rate. With modulation, efficiency can increase to 99% during partial load demand.

Power VT Plus is a fire tube, condensing storage water heater featuring a 3-pass heat exchanger and a fourth pass economizer for maximum energy savings. Modulating burner with up to 4-to-1 turndown is available. MODBUS connectable operating control.


  • 96% thermal efficiency at full firing rate per ANSI Z21.10.3 testing (399 to 900 MBtu) Modulation increases efficiency to 99%.
  • 95% thermal efficiency at full firing rate per ANSI Z21.10.3 testing (1000 to 2000 MBtu) Modulation increases efficiency to 99%.
  • Heaters qualify for LEED certification and may contribute to additional LEED points.
