Recirculation pump
Faster hot water heating is no longer a fantasy, as tankless water heaters are available in the United States and Canada. Rinnai has introduced a built-in recirculation pump into their Ultra Series RUR models. Thermal bypass technology utilizes an integrated pump, internal bypass line, and thermal bypass valve that works together to not wait for hot water.
High definition dual venting
Rinnai Ultra Series Tankless Water Heaters are the only tankless water heaters that offer Concentric Polypropylene or dual-pipe PVC/CPVC venting options in the same model. The dual venting configuration lies on the top so that installers can enjoy maximum convenience. One Concentric vent (with Centrotherm Twin Pipe Adapter) or two PVC/CPVC (3” and 4” configurations) pipes can be used for venting.
Concentric Polypropylene is regarded as the best option based on its superior joint fit, no cure time, quick installation, and reduced penetrations of walls or roofs. Most installations, however, use PVC or CPVC because it is more economical. Rinnai provides both options from the get-go, allowing for faster installation in homes and businesses.
High capacity
The Rinnai RUR98iN 9.8 is the perfect water heater if you are looking for a water heater that can support 4-5 shower heads at a time at medium-low temperature and two shower heads at icy inlet water conditions. This product is designed for high-demand and low-maintenance applications. The RUR98iN gives 5 GPM of hot water in cold-weather states, enough for two fixtures to run simultaneously.
Digital display
It has a digital display, for residential and commercial set up of 98°F – 140°F (37°C – 60°C) heat range is available. It has a remote control that lets you control the temperature despite being far reached from the water heater.

Cons with solution
Expensive installation
This water heater may cost you 1000 to 2000 dollars extra for installation.
Solution– You will have to pay a lot if you choose a professional plumber or electrician for the installation. You are never asked to pay anything extra under the warranty clause, and the unit must be installed by a professional. You can do it yourself by watching the available demos on YouTube. A moderate DYI skill and all the required installation kits will do the trick.
Heavy
Who said tankless units are lighter than conventional heaters? This one weighs 81 pounds.
Solution– Yes, this is true; though RUR98iN is far smaller than traditional tank water heaters, it is not as lightweight as most tankless units. Its weight is due to numerous efficiency features, and safety wraps it comes with.
Frequently Ask Questions
What gas pressure does it require?
A minimum of 15,200 BTU is required, and a maximum of 199,000 BTU can be handled.
What is the minimum PSI and recommended PSI for this heater?
Minimum PSI it requires is 20, Maximum PSI it can work with is 150. However, the manufacturer recommends 60 – 80 PSI working pressure.
In the past, I used a gas water heater and had significant problems with it. Since it wasn’t innocuous for the heater, I had to switch to propane. Again, I had a problem with the wire connections; I could not find the right-sized wire. This time, I wanted to know about these specifications before purchasing the unit.
A sensible move, I would say. Rinnai RUR98iN can do with both propane and natural gas.
Conclusion
Rinnai RUR98iN is a high-capacity condensing water heater with numerous safety features and a built-in recirculation pump. Manufacturers call this series ‘Ultra’ because It has the industry’s most advanced quality venting system and makes you content by providing hot water at a low cost. Although it is a gas-fired heater, you can install it indoors. It works with sensor technology meaning you heat the water only after sensing a flow, which will help your ROI recover fast from the electricity savings. It is a very well-fit choice for you if you want to switch to tankless but are afraid of the wait for hot water in the beginning. Altogether it is a very efficient water heater with a reasonable value.
