Mizudo 3.5kW Under Sink Electric Tankless Water Heater

Stop Waiting for the Water to Get Warm.

We all know the drill: you turn on the kitchen or bathroom tap, wash your hands in freezing water, and right as you're grabbing the towel, it finally gets hot. It's annoying, and it wastes a ton of water.

We built the Mizudo 3.5kW Point-of-Use Electric Tankless Water Heater to fix this exact everyday problem. It's a straightforward, reliable little unit that goes right under your sink. When you turn the handle, you get hot water instantly. Simple as that.

What Makes This Little Heater Different?

• 🤏
  Actually Fits Under Your Sink: At just 1.68 lbs and roughly the size of a hardback book (6.9" × 8.1" × 2.5"), it tucks away easily. You won't have to sacrifice all your cabinet space just to wash your dishes comfortably.
• 🌡️
  No Guesswork on Temp: There’s a clean LED screen right on the front. Just tap to set your water anywhere from 80°F to 113°F, and it stays there. No sudden drops in temperature while you're using it.
• 🔥
  Solid Cast Aluminum Inside: A lot of small heaters use cheap plastic internals that crack or clog. We use a solid cast aluminum heating element. It heats up faster and naturally fights off the hard water scale that usually kills these machines.
• 🛡️
  Safe & Isolated: Water and electricity don't mix. That's why the heating system inside is completely isolated. With built-in overheat and leak detection, you can install it and forget about it.
• ⚡
  Only Runs When You Need It: Operating on a standard 120V line, it only pulls its 3500 watts when water is actively running. Turn the tap off, and it completely shuts down. You're never paying to keep a tank of water hot overnight.
