COMMON TROUBLESHOOTING COMMENTS ON THE OPERATION OF THE EVERHOT→
TANKLESS WATER HEATER
Comment: I don’t have any hot water when I open the tap!
Make sure the gas and electricity is turned on to the water heater. The remote temperature display should have the green light lit when a hot water tap is open and the water heater is operating. Make sure there are no error codes flashing on the display.
Comment: When I was using the hot water, the water got cold!
If you reduced the hot water flow from the tap, you may have reduced the flow below the minimum flow to operate the water heater. If you mix the hot water with cold water at the tap in an attempt to get a temperature below the temperature being produced by the water heater, the hot water flow through the water heater may drop below the minimum flow required to operate the water heater. To remedy this situation, either increase the total water flow from the tap or using the remote temperature controller, decrease the setpoint temperature of the water heater to the temperature desired at the tap.
Comment: White smoke comes out of the exhaust!
During colder weather when the exhaust temperature is much hotter than the ambient air, the moist exhaust gases condense producing a white vapor cloud.
Comment: When I open a hot water faucet I do not immediately get hot water!
Hot water must travel through the plumbing piping to the faucet. This may take from 10 to 30 seconds depending upon the length of cold plumbing pipe the water must travel through.
Comment: After I turn off the hot water tap, the fan on the water heater continues to run!
The fan is designed to continue to run for 65 seconds after the flow of water stops. This is to ensure constant water temperature during frequent short water draws (such as washing dishes) as well as exhausting residual heat and flue gases from the water heater and venting system.
