Rheem RTG-64DVLN Tankless Natural Gas Water Heater Features

  • Venting

Gas-powered tankless water heaters need a venting system. They need a fresh supply of air and proper gas line which will supply the gas to it. With this, these heaters won’t function to their full capacity. The advantage of Rheem is that this model can easily be vented indoors. It won’t cost you much and it can be easily done without any excess issues.

  • Flow rate

Imagine waiting underneath the shower for the hot water to come streaming out so that you can relax under its spray. There’s a high chance that there’s someone in the family who is using another shower to freshen up or someone else is using another outlet to get hot water. In such a case this heater won’t be able to provide much. It has a flow rate of 4 GPM which means that at most it can support two showers, but even then one will be getting pretty cold water. So you must be careful while using it and check if anyone in your family is already using the shower. Also, it heats water on a per-minute basis, so you might experience temperature fluctuations while you are in the shower.

If you are under the shower and enjoying the hot water, you might feel like the water temperature isn’t right and that you need a hotter temperature. In that case, you won’t don’t need to worry. Rheem offers a 35-degree temperature rise option so that you can set it to your preference.

  • Thermostat wire

A great feature of this unit is that it comes with around ten feet of full thermostat wire. Thermostat wires transport electricity to the unit, helps heat the water, keeps the unit running, and more. Having such a long length to work with gives you a lot of freedom when it comes to choosing the area you are going to install the machine in. This gives you a lot of freedom because now you don’t necessarily have to choose a place which is near the power source. Often, places where the power source is already occupied by other machines like TVs, ACs, and such. As such a ten feet long wire will allow you to figure out comfortably where you are going to position the best water tankless heater.

  • Nox

A big concern when installing gas-powered tankless water heaters is the Nox emission. Lack of proper venting system and fresh air can make the situation deadly. This is why making the entire venting system can be made safer and your family will be healthier if there are low Nox emissions. That’s what this unit helps it. It has a low Nox emission and has ones that are eco friendly as well. This makes it easier to manage and maintain. Your family will be safe from the fumes due to the good venting system as well.

  • Installation

If your house has gas piping and other such systems in place, then you will find that it is easy to install this unit. But if not, then you will find it difficult and costly to do so even with the ten feet thermostat wire and direct venting options. You will have to call in a plumber to sort the gas piping out and then get it installed that in itself will be costly. Moreover, you will have to pay for the regular maintenance and plumbing of the pipes as well.

  • Energy efficiency

The unit has a stainless less constructed condense heating exchanger. This means that it can save you up to 82% when it comes to water heating bills. You will save a lot more than what other kinds of standard heaters offer. It can do so because it uses just half of the natural gas that is used by regular tankless gas-powered water heaters. But even with that, it can fully maintain a continuous supply of hot water without wasting any form of energy. This will certainly save you a lot of money and effort in the long run.

  • Digital display 

Gone are the days of knobs that were used to control the temperature. Now there is a digital display that will show you the water temperature. This will make it very easy for you to change the temperature settings and also keep control over the maintenance codes.

Pros

  • Digital display for temperature
  • 82% energy efficiency
  • Low Nox emissions
  • Ten feet thermostat wire
  • Direct venting

Cons

  • Just 4 GPM water flow
  • Not easy to install due to various parts

Verdict

Rheem RTG-64DVLN is a very affordable and reliable solution to your water heating problems no matter the weather. This unique unit will give you a continuous supply of hot water. The best part is that it is very energy efficient as well. You won’t need a lot of space to store it too. This unit is great for both large and small families. You will be able to control two units using the EZ cable and control it as one using the UMC-117 remote.

As such, it comes with a lot of features and benefits for sure, but there is one problem which users tend to face and that is in regards to mission parts. Oftentimes, users have complained of missing parts. This, in turn, affects the accessibility and usability of the product. So, overall it comes with advanced electronic controls which optimizes its user-friendliness and reliability, but the lack of parts and low water flow can put a damper on use.
