Choosing a Water Heater in Illinois
Illinois's cold winters change the math on water heaters. A heat pump (hybrid) unit still works, but it should sit in a heated space — placed in an unheated Illinois basement it loses efficiency. For gas-connected homes, a high-efficiency condensing tankless gas unit (0.90+ UEF) is often the most reliable choice, delivering endless hot water without a standby-loss tank.
