Titan Scr-3 Tankless Water Heater Troubleshooting

Louis Gutierrez

The SCR3 N-160 Titan is an on-demand tankless water heater. It heats up the water when you turn on a hot water faucet in the house; unlike a regular tank water heater, it does not have a storage tank where it constantly heats the water. The SCR-3 can have a few problems during installation; learn to troubleshoot and diagnose these problems correctly to get the heater to work correctly and safely.

Tankless water heaters use less energy than tank water heaters.
  1. Check for leaks on the your Titan SCR-3's fittings. If it has begun to leak via the fittings, remove the plumbing from the fittings using a wrench and remove any tape or paste from the fitting. Reinstall the plumbing into the fittings, and tighten the fitting with the wrench.

  2. Touch your water heater's electrical wires to test for overheating. If they feel excessively hot, turn off the circuit breaker to the water heater. Contact a licensed electrician to inspect the wiring; in this case, the installer most likely used the wrong wire gauge. Discontinue use of the water heater with the wrong wire size, as it can lead to a fire. Do not attempt to replace the wire yourself; only a licensed electrician can obtain the required permits to fix this problem.

  3. Inspect the water temperature coming out via the water faucets in the house. If the temperature is not adequate, increase the temperature setting on the Titan SCR-3. If the temperature does not change when you change it on the Titan SCR-3, you may need to replace it with a larger model. Read the water heater's packaging to determine the capacity it can handle.
