ecobee + a 24V relay to replace the Ebwh1164kr’s switching logic. Part 6: Common Misconceptions About "Ebwh1164kr Better" Myth 1: "The OEM part is always better." False. OEMs design to a price point, not maximum lifespan. Aftermarket upgrades often use better internal components (e.g., silver-cadmium oxide contacts vs. plain copper). Myth 2: "Higher wattage means better." Dangerous. Do not install a 3kW unit where a 2kW Ebwh1164kr was used unless you verify wire gauge and breaker size. "Better" means matching load, not exceeding it. Myth 3: "All replacements need an electrician." Half-true. If you are matching voltage, amperage, and terminal types (spade to spade), this is a DIY-able 20-minute swap. However, if modifying circuits, hire a pro.
