Cold groundwater and winter outages both put strain on your water heater
Water heaters in Troy work harder from October through May, pulling in groundwater that's already cold and heating it further on nights that average 17°F. That extra work falls on the heating element or the burner, and over years it's often the first part to fail.
Rensselaer County has logged 38 winter storms and 301 damaging wind events over the past ten years, and across New York, 11% of households lost power for a full day or more in 2024. A gas water heater with a standing pilot will keep running through an outage, but if yours has an electronic igniter or you have an electric unit, the power has to come back before it will. Most reset on their own once it does. If yours doesn't, or the water never gets hot again, that points to a problem worth having looked at.

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 often the tank itself has rusted through, and once that happens the tank has to be replaced, not repaired. Water at the bottom can also come from the drain valve if it is not fully closed, or from the T&P valve above discharging down the side of the tank. A loose drain valve or fitting is worth checking first since that part can be tightened or replaced. If the tank itself is wet all the way around the bottom, a contractor can confirm whether it is the tank or a fitting causing it.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a thermocouple that has worn out and no longer holds the gas valve open once you let go. A draft blowing across the pilot can also blow it out, and a dirty pilot orifice can starve the flame enough that it will not stay lit. If it lights and holds while you hold the button but goes out as soon as you release it, that points straight at the thermocouple. A contractor can test it and replace it if that is the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairable without replacing the whole unit. Mineral buildup on the heat exchanger is common and is cleared with a descaling flush. Ignition failures, sensor faults, and venting blockages are also things a contractor can diagnose and fix on the unit you have. Replacement usually only comes up when the heat exchanger itself has failed.
