Tankless Water Heaters
Reliable Hot Water Without the Storage Tank
Tankless water heaters can deliver efficient, on-demand hot water while taking up less space than a traditional tank system.
At The Water Heater Specialists, we diagnose, repair, replace, and install residential tankless water heaters throughout the Inland Empire.
Whether your system is displaying an error code, producing inconsistent temperatures, making unusual noises, leaking, or has stopped producing hot water entirely, we help identify the problem and explain your options clearly.
Expert service for industry-leading brands:
Having Problems With Your Tankless Water Heater?
No Hot Water? Error Code? Temperature Problems?
Tankless water heaters rely on several systems working together, including water flow, gas or electrical supply, ignition, venting, sensors, controls, and internal heat-exchanger components.
When one part of the system is not operating correctly, you may experience:
- No hot water
Water that suddenly turns cold - Inconsistent water temperature
- Reduced hot-water flow
- Error codes
Ignition or flame failures - Unusual noises
- Leaking components
- Frequent system shutdowns
- Hot water taking longer than normal to arrive
- A unit that repeatedly needs to be reset
The Water Heater Specialists can diagnose the problem and help determine whether repair, maintenance, or replacement makes the most sense.
Tankless Water Heater Repair
Not every tankless problem means the entire system needs to be replaced.
We diagnose common tankless water heater problems, including:
- Ignition failures
- Flame-sensing problems
- Error codes
- Temperature fluctuations
- Flow-related problems
- Failed sensors
- Control-board issues
- Leaking valves or fittings
- Scale and mineral buildup
- Venting-related problems
- Condensate drainage issues
- Reduced heating performance
- Complete loss of hot water
After diagnosing the system, we explain what we found, what can be repaired, and the cost before approved work begins.
Tankless Water Heater Replacement
Tankless water heaters eventually reach a point where continued repairs may no longer make financial sense.
Replacement may be appropriate when:
- The system has repeated failures
- Major components have failed
- Repair costs are becoming excessive
- Parts are difficult or impossible to obtain
- The existing unit is improperly sized
- The system no longer meets household demand
- The current installation has serious venting, gas, drainage, or safety issues
- You want to upgrade to newer equipment

Why Choose
The Water Heater Specialists?
Water heaters involve much more than connecting two water lines.
A safe and reliable installation may require proper venting, gas connections, electrical work, drainage, earthquake protection, pressure control, equipment sizing, and code compliance.
At The Water Heater Specialists, we focus on the complete installation rather than simply replacing the tank and ignoring the surrounding conditions.

Antonio M.
Had Ed install a heater and remote control panel. Really quick response and price was comparable to other quotes. Cleaned his job site and made sure everything worked properly. He also made sure I was familiar with new equipment and controls.
Michael L.
If I could give six stars, I would!!! I used this business to replace my heater and from the communication to the coordination to the installation, the whole process was perfectly managed, along with my expectations which were exceeded by a mile. Price was very reasonable given the unit costs and the work was top notch– replaced the old heater with a new one and the heat circulation and improvement are extremely noticeable. Do NOT hesitate to use them! Thank you so so much! A+++++
Brenda D.
He ordered the parts before knowing what was wrong with our heater. He then scheduled a time to come to our house brought his parts and just like a true professional he fixed the problem (display board). He even checked to make sure the heater was properly functioning before leaving. Ed has reasonable fees and when our heater dies he will be the one to do the job.
This one is the best. Thank you Ed.
Debra Santibanez
