Cold groundwater means longer run times in Woodbury
Groundwater here runs cold, and from October through May it runs colder still, with winter nights averaging 10°F. Your water heater has to work harder to bring that water up to temperature, and it runs longer to do it. That extra runtime wears on the heating element in an electric unit and on the burner and thermocouple in a gas one.
Woodbury has seen 34 winter storms over the past ten years, and storms like that knock out power. A gas water heater with a standing pilot will keep making hot water through an outage. One with electronic ignition will not, and it will need to be relit once power is back on.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- Most of the time it means the tank itself has rusted through and is failing. Water heaters corrode from the inside over the years, and once the tank wall is breached it will not seal itself back up. It can also be a loose drain valve or a fitting weeping from above and running down the side, which looks the same on the floor. A contractor can tell the difference in a few minutes, but if the tank is the source, it needs to be replaced, not patched.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out it stops sending that signal even with the flame lit, so the valve shuts the gas off. A dirty pilot orifice or a draft blowing the flame out can cause the same thing. A contractor can test the thermocouple on the spot and replace it if that is the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a blocked vent are common causes and none of them mean the unit is done. A contractor can flush the system, test the igniter and sensors, and check the venting to find out which one it is.
