Tankless Water Heater Reviews: The Top Three

The technology of tankless water heaters has offered many solutions to the problems of conventional tanked water heating systems. With better energy efficiency and an endless hot water supply, people find it hard to pass on this investment. But before you jump on the bandwagon and buy one, you should first browse through the various models from different brands. By comparing them to each other, it will be easier to choose which one will be the best option for you.

 Here are the three best tankless water heater reviews:

1. EcoSmart ECO 18

One of the best budget units is the EcoSmart ECO 18. It can supply around 1.8 to 4.3 gallons of water per minute, which should be enough for one shower and one faucet simultaneously. It even comes with a digital remote-control system and over-heating controller technology for easier operation.

Despite its low price of only $368, this model has up to 99% energy efficiency. Thanks to its self-modulating technology, you can save up to 60% on water heating costs. The unit itself is stylish, compact, and incredibly lightweight. Compared with other affordable tankless water heaters, this one is the best option for small houses.

2. Rinnai V65EN

If you like the idea of an outdoor unit for your tankless water heater, then the Rinnai V65EN is worth considering. Not only is it safer for residentials, but this model also has certifications to install on mobile homes.

Depending on the groundwater temperature, the hot water supply can go up to 6.5 gallons per minute. It is enough for 1-3 fixtures at the same time.

Compared to other units with similar specifications from different brands, this one offers the best value on the price-to-benefit comparison. Its energy efficiency is 84%, which is impressive because most middle-tier units are only 70% efficient.

Powered by natural gas, the unit is also low on NOx emissions. Even the price tag itself is still comparably inexpensive, around $680. Being an excellent brand in water heaters, Rinnai also offers similar units for indoor usage, propane-powered, or higher capacity.

3. Rheem RTGH-95DVLN

To reap the ultimate benefits of a tankless water heater, there are no other options that could exceed the Rheem RTGH-95DVLN. The supply of 9.5 gallons of hot water per minute can accommodate up to 4-5 fixtures, making it suitable for large houses. This Energy Star certified unit can also help you significantly conserve energy with its 95% efficiency rate.

This unit also has a built-in recirculation pump for convenience and efficiency. Other advanced features are:

  • A self-diagnosis system.
  • An overheating protection system.
  • A built-in blower.
  • Freeze protection that can work from as low as -30 degrees.

Besides this natural gas-powered unit, the Rheem also has a similar model powered with propane.

The tankless water heater is the modern solution to the hot water supply. However, with so many models available in the market, you need to be specific about your needs. You will get the optimal benefits if you buy the right one and get it installed properly!
