Our Rinnai Water Heater Services
Installation & Replacement
Rinnai units offer flexible venting options that make them ideal for both new construction and tank-to-tankless conversions.
We provide professional water heater sizing and installation for all Rinnai models throughout the Las Vegas valley.
- SENSEI™ RX Efficiency: We install high-efficiency condensing units featuring stainless steel heat exchangers that resist corrosive pitting from hard water better than standard copper.
- Smart-Circ™ Technology: For large homes in Summerlin and Henderson, we program the intelligent recirculation pump to learn your usage patterns, eliminating “cold water sandwiches” and reducing water waste under SNWA guidelines.
- Precision Venting & Gas Load: We verify your gas load (up to 199,000 BTUs) and install concentric or dual-pipe Schedule 40 PVC/CPVC venting. We never reuse unsafe aluminum or galvanized pipe.
- Service Valves: Every installation includes service valves on the unit, allowing for mandatory annual vinegar flushes to remove Las Vegas scale without shutting off your main water supply.
Repair & Maintenance
If you are dealing with error codes or inconsistent hot water issues with your Rinnai water heater unit, Water Heaters Today works hard in order to diagnose the situation and get your water heater repaired the same-day. We are always stocked with OEM Rinnai water heater parts.
With our decades of Rinnai water heater expertise, we will identify the root cause of why your water heater is malfunctioning.
- Error Code Diagnostics: We resolve common issues like Code 11 (Ignition Failure), Code 12 (Flame Failure), and Code LC (Scale Build-up) quickly.
- Professional Descaling: We circulate a safe descaling solution through your unit for 45-60 minutes to dissolve calcium buildup that insulates the heat exchanger and causes overheating.
- Component Cleaning & Replacement: We clean inlet water filters, flame rods, and igniters with emery cloth to restore strong electrical signals and proper combustion.
- Flow Sensor Calibration: We adjust internal bypass valves and flow sensors to guarantee discharge temperature remains within ±2°F of the setpoint, even during high-wind desert conditions.
Why Homeowners Choose Water Heaters Today LLC for Rinnai Systems

It does require a licensed water heater professional like us at Water Heaters Today LLC to perform the combustion analysis and verify that the gas valve is clocked correctly for your property.

- No “Swap Box” Service: We don’t just hang a new unit. We make sure your hot water system is perfectly set-up before we leave your property. This includes everything from verifying gas supply, upgrading venting to PVC where applicable, and programming Smart-Circ™ features for maximum efficiency.

Have Any Questions?
With the 16+ grains of hardness in our water, a Rinnai unit lasts 15–20 years only if it is flushed annually. Without descaling, scale buildup will insulate the heat exchanger, causing it to overheat and crack.
Code 11 is a common ignition failure code. It usually indicates that the unit is not receiving gas or the igniter is dirty. Our technicians can quickly diagnose the root cause. Whether it’s a gas valve issue or a simple cleaning requirement – We can restore your hot water.
Rinnai’s warranty specifies that water hardness should be below 12 grains per gallon (gpg). Since Las Vegas water is significantly harder, we strongly recommend a water softener or a scale-prevention system to protect your stainless steel heat exchanger.
Yes. By installing the Control-R™ Wi-Fi Module, you can monitor system health, receive error code alerts on your phone, and integrate with smart home systems like Alexa or Google Home.
Condensing (SENSEI™ RX): Higher efficiency (0.96 UEF), uses cool-to-the-touch PVC venting, and captures more heat.
Non-Condensing (RE Series): Lower upfront cost, requires expensive stainless steel (Category III) venting, and has a UEF of approximately 0.81.
Yes. Most Las Vegas homes can be converted in a single day. We remove your bulky old tank and mount the compact Rinnai unit to the wall.
Our team handles the necessary updates to your gas lines and venting to ensure everything meets local codes. You’ll gain extra floor space and enjoy endless hot water immediately.
