DRE/DVE MODEL DIFFERENCES

This Instruction Manual covers two models of commercial electric water heaters; DRE models and DVE models. These two models are equipped from the factory with different controls.

DRE models are factory equipped with surface mounted thermostat/ECO combination controls. DVE models are factory equipped with an electronic control system.

In this Instruction Manual “DRE” models are referred to as: “Surface Mount Control” models.

In this Instruction Manual “DVE” models are referred to as: “Electronic Control” models.

*Figured at 1 KW (3413 Btu) = 4.1 gallons at 100°F temperature rise.

To determine recovery rate per minute, divide recovery rate per hour by 60.
