What to do when you're not getting enough hot water from your Regency/Reliance gas water heater
Check the thermostat setting. The typical water heater thermostat temperature setting is 120 degrees. Raise the thermostat setting slightly if it's set below 120 degrees.
Drain and flush tank sediment. Tank sediment interferes with water heating so drain and flush the tank to remove sediment.
Check the gas supply. Make sure that the gas supply cut-off valve is fully open and that you have an adequate gas supply provided to the water heater.
Check water heater tank size to see whether it's adequate for your hot water usage needs. You'll keep running out of hot water if the water heater is too small for your needs.
Check piping insulation. Repair any damaged insulation and install new insulation if needed to keep water hot as it travels through pipes.
Top replacement parts for Regency/Reliance gas water heaters
Gas valve assembly. The gas valve assembly monitors tank water temperature and cycles the burner on and off to maintain set water temperature.
Thermocouple. The thermocouple detects whether your pilot light is on by generating a very small electrical current powered by the heat of the pilot flame. If the gas valve assembly doesn't sense the small electrical current provided by the thermocouple, or the thermocouple cools, it assumes that the pilot light is off and shuts down the gas.
Pilot igniter. The pilot igniter lights the pilot burner when the button is pushed.
Temperature-pressure relief valve. The temperature-pressure (T&P) relief valve is a safety device that automatically opens to discharge hot water in the event of excessive temperature and/or pressure inside the tank. Replace the T&P valve if it leaks or malfunctions.
