After using one for several months, I want to share my experience and tips to help you decide if it’s the right choice for you. Here’s what I learned during my research and purchase journey.
Why I Chose a Tankless Water Heater
Before diving into Mizudo specifically, I want to explain why I opted for a tankless model. Unlike traditional water heaters with large tanks, tankless units heat water on demand. This means I don’t have to wait for a tank to refill or worry about running out of hot water. Plus, they’re more energy-efficient, which helped me save on my utility bills.

- Energy Savings: My electricity bills noticeably decreased after installation. Mizudo’s energy-efficient technology really delivers on its promise.
- Easy Installation: I was able to install the unit myself following the clear instructions, although professional help is always recommended if you’re not comfortable with electrical work.
- Safety Features: The built-in temperature controls and automatic shut-off gave me peace of mind.
Key Factors I Considered Before Buying
If you’re thinking about getting a Mizudo tankless water heater, here are the main factors I focused on:
- Flow Rate (GPM): I calculated my household’s peak hot water demand. Mizudo offers various models with different flow rates, so it’s important to choose one that meets your needs. I went with a unit rated for 3.5 gallons per minute, which suits my family of four.
- Power Source: Mizudo units come in electric versions. Make sure your home’s electrical system can handle the load. I upgraded my circuit breaker to accommodate the heater’s requirements.
- Temperature Settings: Being able to set the water temperature precisely was a big plus for me. Mizudo’s digital controls made this easy.
- Warranty and Customer Support: Mizudo offers a solid warranty, and I found their customer service responsive when I had a few questions before purchasing.
