In this video I’m walking through why I chose the Rheem IKONIC tankless water heater and what it’s actually like once it’s installed. The big headline is simple: tankless means an endless supply of hot water. With five people in my house, I was tired of “timing showers” and worrying about someone running the dishwasher or washing machine right when another person needed hot water. I also put the performance to the test. This unit is rated for 11.2 gallons per minute, and in my real-world testing I ran all five showers at the same time at my normal shower temps—and it kept up. That’s been consistent so far, and it’s honestly a little better than what the specs made me expect. What makes the Rheem IKONIC a smart home win is the Wi‑Fi + EcoNet app, and the fact that I can pull it into Home Assistant. That means I can use its data for automations, and I’m not just upgrading comfort—I’m adding something my smart home can actually “see” and react to. If you’re still on a dumb tank heater, I think this is one of those upgrades that’s genuinely worth it.
