DHE tankless electric water heaters must be correctly sized and you should consult the sizing guide listed as “Product Information: Use and Care Guide” on the “Info & Guides” tab to determine the correct size AquaPower DHE for you
This is a DHE Pro model with Advanced Flow Control™ that automatically reduces the output flow rate to maintain the set temperature in cases when demand temporarily exceeds capacity
DHE 12 models require a minimum of 100 amp total service to the residence, with 1 separate 60 amp breaker and 6 gauge copper wiring for the DHE 12
DHE 12 models require 240 or 208 volt electric service, and have a maximum output of 12,000 watts at 240 volts or 9,000 watts at 208 volts
AquaPower DHE tankless water heaters supply endless hot water at a constant and steady temperature from 86 to 140 F (30-60 C) that can be set on the front panel
The flow rate you achieve from a DHE 12 or any tankless water heater depends on how powerful the unit is and the temperature difference between the incoming cold water and the hot water being delivered
AquaPower DHE tankless electric water heaters are 99% efficient and typically result in savings of 15-20% in comparison with electric tank water heaters
A DHE must be installed vertically, water fittings pointing down, with detachable connections such as braided flex connectors to allow periodic filter cleaning and flushing for scale, and an anti-scale filter is recommended if hard water is present
Professional installation recommended
