I like the adjustable power settings and how quickly it heats water. My only issue was I needed a professional to install it, which added to the cost. Other than that, it works perfectly!
The energy efficiency is amazing, and I�ve noticed significant savings on my electricity bill. Plus, it delivers hot water on demand, easy installation, and it lets you adjust the output kilowatts. The sleek design is a bonus too.
