When you had your Tankless Water Heater in Phoenix AZ put in, you were all set for hot water on demand, all the time. At the time of the installation tankless water heater systems generally work quite well, but some systems develop problems as time goes by. Let's look at some troubleshooting solutions for some of the most common problems that creep up. Take a look at the electric power circuit that feeds the heater. Also, look at the water and gas lines to the heater. The shut-off valves may be closed, so opening them is an easy fix. Then take a look at the tap going to the heater. Is it open? Are there any blockages in the piping line? If it's winter, are any of the pipes frozen? Next, check out the burner. Does the flame rod bring sparks?
Finally, look on the control panel for an error code. The panel keeps the heater from operating while the problems it has noticed are still in place. Check the thermostat to make sure the water temperature is not set too high. If everyone in the house comes out of the shower looking like a scalded lobster, turn the thermostat lower. If you have blockages in the water filter or somewhere in the plumbing, you'll have less water traveling through the system at a set time, so the heating action makes it hotter. Clean out your heater's plumbing to restore normal flow.
Has sediment built up in your Tankless Water Heater in Phoenix AZ? It's time to flush and descale it. Check the sensor for temperature at the water output point. The sensor might not be working properly. These are the two most common problems that people encounter with their tankless hot water heating systems. If these troubleshooting steps do not work for you, contact a professional plumber to take a look.
