One of the bigger benefits is that most people can install this tankless water heater themselves. The Rinnai RUR98iN comes with its own installation manual, which ensures you can install it yourself efficiently.

Water Heating Recirculation Technology

One of the major benefits of the Rinnai RUR98iN is its water heating recirculation technology; this means you do not need a special return line to keep the warm water flowing. It also means that no additional energy and time is required to get warm water.

The Rinnai RUR98iN is equipped with TermaCirc360, which includes unique bypass technology, an internal pump, timer, and bypass valve. By using a combination of these components, the Rinnai RUR98iN can deliver hot water faster while remaining eco-friendly.

Save More Energy With Additional Control Options

The Rinnai RUR98iN is a device that comes with many control options. For example, it comes with a digital controller and a special programming option; this means you can ensure your home does not use any energy that is not needed at the time. Evidently, this will save you money on your utility bills too.

Good Capacity While Remaining Eco-Friendly?

As we have stated a number of times previously, the Rinnai RUR98iN is also an eco-friendly device; this not only through the presence of the recirculation technology, but also the design of the tankless water heater.

The Rinnai RUR98iN actually contains an ultra-low NOx gas burner, which are friendlier for the environment overall. However, this feature also provides plenty of control. The burner can provide you with 9.8 GPM of hot water. So, even if you have more than two baths in your home, this tankless water heater can certainly handle it.

Interestingly, consumers can adjust the capacity of their Rinnai RUR98iN as required. The Rinnai RUR98iN contains a gas valve, which can be used to reduce the waterflow rate. For example, if you only use the tankless water heater for a quick handwash or a shave, then you can reduce it to 0.26 GPM.

Improvements Made Compared To Previous Rinnai RUR98iN Models

The manufacturers at Rinnai have made some improvements to the Rinnai RUR98iN. One of the biggest changes is the direct vent unit, which contains a concentric vent and twin pipe system on the indoor unit. However, the outdoor unit does not contain this vent, as it uses the fresh air from the outside.

Numerous Safety Features

Customers who purchase the Rinnai RUR98iN can also count on a bunch of safety features. This device includes boiling protection, an RPM check for the internal fans, thermal fuse, frost protection, over-current protection and so much more. So, if the safety of your tankless is paramount, then the Rinnai RUR98iN will not disappoint.

Are There Any Downsides To The Rinnai RUR98iN?

The downsides to the Rinnai RUR98iN are very few and far in between. However, for this to be an accurate and all-encompassing review, we must mention them here.

As we mentioned in our overview of benefits, the Rinnai RUR98iN can be installed by the customer. However, some people may not be that familiar with an installation of such a device, despite the assistance provided by the customer support team or the installation manual. If this is the case for you, you may have to acquire someone to help you with the installation.

The price of the Rinnai RUR98iN is also slightly higher than most tankless water heaters out there. However, when you look at the overall construction and the benefits it provides, the price is still value for money.

During the installation, you must execute a venting process too. However, the Rinnai RUR98iN installation kit does not contain the equipment needed for this. Therefore, venting equipment may have to be acquired separately.

Another fact consumer must take into consideration is that their warranty may become void if not installed and checked by a technician. If you want to benefit from the lengthy warranty period that this tankless water heater provides, then it is best to have it installed by a recognized technician.
