Best Under Sink Tankless Water Heater 120v

Tired of running out of hot water in the middle of a shower? An under-sink tankless water heater can be the perfect solution. These compact units can provide an endless supply of hot water on demand, without the need for a bulky storage tank. And with a 120v model, you can easily install it yourself without the need for an electrician.

But with so many different models on the market, it can be hard to know which one is right for you. Here are a few things to consider when choosing an under-sink tankless water heater:

Flow rate: This is measured in gallons per minute (GPM). The higher the GPM, the more hot water the heater can produce. For a single sink, you'll need a heater with a GPM of at least 1.5. For multiple sinks, you'll need a heater with a GPM of at least 2.5.
Temperature range: This is the range of temperatures that the heater can produce. Most heaters have a temperature range of 80-120 degrees Fahrenheit. However, some heaters can produce higher temperatures, up to 140 degrees Fahrenheit.
Energy efficiency: This is measured in Energy Factor (EF). The higher the EF, the more energy efficient the heater is. An EF of 0.95 or higher is considered to be energy efficient.
Size: Under-sink tankless water heaters are typically small and compact, but they can vary in size. Make sure to measure the space under your sink before you purchase a heater.
Price: Under-sink tankless water heaters can range in price from $100 to $500. The price will vary depending on the features and capabilities of the heater.

Once you've considered these factors, you can start shopping for an under-sink tankless water heater. Here are a few of the best models on the market:

Eccotemp FVI-120: This is a great option for a single sink. It has a GPM of 1.5 and a temperature range of 80-120 degrees Fahrenheit. It's also energy efficient, with an EF of 0.95.

No matter which model you choose, an under-sink tankless water heater can be a great way to save money and energy while enjoying an endless supply of hot water.
