Cold winters and outages both take a toll
Hartford winters run cold, averaging 21°F on December through February nights, and that cold water coming in means your water heater runs its burner or element longer just to hold a setpoint. That extra cycling wears on the thermostat and the heating element or gas valve over time.
Power matters too. In Connecticut, 20% of households went at least 24 hours without power in 2024. An electric water heater that loses power for that long can come back needing a reset, or it may not come back at all if the element or thermostat gave out.

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?
- The most common cause is the tank itself failing from the inside, where years of sediment and mineral buildup wear through the steel and let water seep out at the bottom seam. It can also be the drain valve, which loosens or cracks over time, or a fitting where a pipe connects to the tank. A leaking tank cannot be repaired. A loose valve or fitting sometimes can, but a contractor needs to see where the water is actually coming from to tell you which one it is.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep gas flowing. When it fails, the valve shuts the gas off as soon as you let go of the button, even though the flame was lit a second ago. A dirty pilot orifice or a draft blowing the flame around can also cause it, but a worn thermocouple is the usual reason. A contractor can test it and replace it if that's the problem.
- Can a tankless water heater be repaired?
- Yes, in most cases. The heat exchanger, igniter, flow sensor, and venting are all parts a contractor can inspect and replace individually. Mineral scale buildup inside the unit is one of the more common issues, especially in areas with harder water, and that can often be flushed out rather than requiring a new unit. Whether repair makes sense depends on the age of the unit and which part has failed, so a contractor will need to look at it to say for sure.
