Cons

  • In some units few of the primary parts that are essential for operating the unit are absent
  • Although installation is easy and quick but the heater needs several parts and pieces that are to be purchased separately from a hardware store and thus, increases the unit’s overall cost
  • One of the most common defect that is found in almost all tankless heaters is present in this model as well, which is that it heats water on a per minute basis and this means water temperature fluctuations can occur giving the users “cold sandwich effect”

Installation and Specifications

The heater can be installed manually because it comes with a thorough step-by-step guide for users. You need to install this heater with 7.6-cm/12.7-cm or 3-in./5-in. diameter Rheem-approved concentric venting pipe or a UL-approved Category III Coaxial Stainless Steel appliance venting pipe. The unit needs 3x5inch concentric B-vent and vent cap that is fixed on the outer portion. The unit comes with water valves which helps the heater maintain hot and cold water release.

Common Problems

Missing parts is certainly one of the main problems that users can face and it also substantially affects the unit’s usability and affordability. However, since the drain is absent and the function is performed via vent therefore, the unit is very compact, advanced, and innovative and serves as an ideal heating solution for indoor usage.

Conclusion

There are several problems with this product, and the missing parts certainly put a damper on its usability, but that is not to say that the absence of these parts render the product unusable. The absence of the drain is made up for by the vent, and so this RTG model can still run fairly efficiently and can serve as an adequate water heating solution for your home, and certainly beats its tanked water heater competition, whilst being mostly on par with other tankless water heaters.
