Water heaters have come a very long way over the past few decades. Before, people could only depend on their big bulky tanks, and if the water tank was not large enough, or the warm water ran for too long, there was always worry about not having hot water. Either worry about running out or one would have to wait in between showers, laundry, and running the dishwasher. There is nothing more frustrating than trying to take a nice warm shower, do laundry, and/or dishes and run out of hot water. Conventional water heaters are not nearly as efficient as the latest technology on offer… the tankless water heater. One of the brands that stands out is Rinnai. Read our Rinnai tankless water heater reviews below to find out what are the best models from the brand.

Rinnai Tankless Water Heater Problems and Troubleshooting
There are some common problems associated with the tankless water heaters, no matter what brand or manufacturer is purchased. Even though they offer all of these great benefits, they are not perfect – as nothing is on this planet. The good thing is though; troubleshooting is simple when it comes to the various Rinnai tankless water heaters. An error code will pop up on both the actual heating unit and digital remote that comes with the system. Depending on the code, will help people narrow down what exactly needs to be fixed and what caused the problem. Some of the most common issues are listed below:
- Hard Water
- Water Flow/Pressure
- Water temperature too high for unit
- Fan/Cooling Problems
- No Ignition/Flame Failure
These issues listed above are typical and are simple fixes in the assumption that everything has been properly hooked up, there are no leaks with hoses, and the electronics parts of the unit are not malfunctioning. No matter what issues people may run into eventually with the Rinnai tankless water heaters, there are many preventative measures that people can take after purchase. It is important to carefully go over the instruction guide, to ensure that the unit remains functioning as it should and to maximize its lifespan.
If for example one is experiencing issues with the ignition, the first thing to check is if the hot water tap is actually open. The burner absolutely will not ignite if this is the case – which is more from people not realizing this fact. The next thing that one should check is the pressure levels of the gas coming into the unit. If there are any fluctuations in water and/or gas pressure, the water-heating unit itself could stop working. It is more for protection reasons than anything else, a fail proof system to avoid leakage.
Conclusion
Overall, people in the Rinnai tankless water heater reviews have been very pleased with its line of tankless water heaters. They are properly priced for what they offer and they offer a great deal of benefits while taking up minimal space. The warranty provided by the company is simply amazing and offers much comfort to those who choose to take this route.
