If it takes a long time to get hot water at the fixtures with your Takagi water heater, remember that the delivery time depends on the piping length between the heater and fixtures. The longer the distance, the longer it takes. If you want hot water faster, consider a hot water recirculation system.
What to do if hot water is not available with Takagi Water Heater?
If hot water is not available when a fixture is opened, verify the unit has a 120 VAC, 60 Hz power supply. If you're using a remote or temperature controller, ensure it's powered on. Check that the gas and water supply valves are fully open. Also, see if the filter on the cold water inlet is clean. Ensure the hot water fixture is open enough to draw at least 0.5 GPM through the water heater. Check if the unit is frozen and confirm there is enough gas in the tank/cylinder for propane models.
Why does Takagi Water Heater hot water turn cold?
If the hot water turns cold and stays cold, ensure the flow rate is sufficient to keep the water heater running. If a recirculation system is installed, check that the recirculation line has enough check valves. Verify the gas supply valve is fully open and the filter on the cold water inlet is clean. Make sure the fixtures are free of debris and obstructions. Also, check if the flow rate is too low.
How to fix not hot enough water from Takagi T-H3J-DV?
If the water from your Takagi water heater isn't hot enough, compare the flow and temperature using the charts. Check for cross plumbing between cold and hot water lines. Ensure the gas supply valve is fully open, the gas line is properly sized, and the gas supply pressure is sufficient. Also, verify that the set temperature isn't set too low.
Why is there fluctuation in hot water temperature with Takagi T-H3J-DV?
If you experience fluctuations in hot water temperature, start by checking if the filter on the cold water inlet is clean. Also, verify that the gas line is properly sized and the supply gas pressure is sufficient. Finally, inspect for any cross-connections between the cold and hot water lines.
What to do if Takagi Water Heater water is too hot?
If the water is too hot, check if the set temperature is set too high.
