A Rolesville homeowner experienced their water heater intermittently stopping and not producing hot water.
Chris and Alex determined that the issue was related to the water heater's PCB board.
Chris contacted Rinnai, the manufacturer, to request a replacement PCB board. The part was sent to the shop and was expected to arrive by Thursday morning.
The homeowner was informed that the replacement part would be installed promptly upon arrival, ensuring a return to consistent hot water.
If your tankless water heater stops producing hot water intermittently, it might be a faulty PCB board. Keep the manufacturer's contact handy for quick troubleshooting and part replacements.

Answered by our licensed technicians serving Rolesville.
The U.S. Department of Energy reports 24% to 34% energy savings for homes that use less than 41 gallons of hot water daily, and 8% to 14% for higher-usage homes. For a typical Apex household, that translates to roughly $100 to $200 per year in gas savings.
Yes, when properly sized. A correctly selected tankless unit for a 3-bathroom home can deliver 8 to 10 gallons per minute — enough for two showers, a dishwasher, and a sink running simultaneously. Sizing is critical, which is why we perform a detailed demand calculation.
In the Triangle area with our moderately hard water, we recommend annual descaling to flush mineral buildup from the heat exchanger. This 45-minute service maintains efficiency, prevents error codes, and keeps your manufacturer warranty valid.
If your current tank water heater is approaching 10 to 12 years old, a tankless replacement makes excellent financial sense. You'll gain endless hot water, cut energy costs, reclaim floor space, and install a system that lasts 20+ years. The higher upfront cost pays back through energy savings and longevity.
