The Eccotemp Smart Home Indoor is a natural gas tankless water heater rated at 4.0 GPM, built for small to medium households. It connects over Wi-Fi and works with Amazon Alexa and Google Home, so you can set schedules, change temperature, watch usage statistics and get maintenance alerts from a phone. Like any tankless unit it heats water on demand, which avoids the standby loss of a tank. Its 4.0 GPM ceiling is modest: it handles one shower plus a sink comfortably but not two showers at once, and it is for indoor vented installation only.
