What winter here does to your water heater

New Haven County homes run their heat from October through May, and winter nights average 25°F that whole stretch. Cold water coming into the tank in those months means the burner or the heating element has to work harder to bring it up to temperature. That extra work is what wears down a heating element or burner assembly over the years, and it shows up as water that never gets quite hot enough, or runs out faster than it used to.

In Connecticut, 20% of households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps making hot water through an outage like that. One with electric ignition will not restart on its own, so if your water is still cold after the power comes back, that is worth checking before you assume something is broken.

A new water heater would cut about $100 a year off hot water for a typical Connecticut home.

  • A new high-efficiency gas water heater$240 a year
  • A heat pump water heater$300 a year
  • An older gas water heater$340 a year

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 is holding water it can't hold anymore, which means the tank needs to be replaced, not patched. It can also be a loose drain valve, a failed temperature and pressure relief valve, or condensation if the water heater is new and running for the first time. A contractor can tell the difference by looking at where the water is actually coming from. If the tank is rusted through, that's the end of its life, and no repair will fix it.
Why won't the pilot light on my water heater stay lit?
Usually the thermocouple has worn out and can no longer hold the gas valve open once you let go. It can also be a draft blowing the flame out, a dirty pilot orifice, or a gas supply issue. A licensed contractor can test the thermocouple in a few minutes and replace it if that's the cause. Don't keep trying to relight it over and over if it won't hold. That points to a part that needs replacing, not a fluke.
Can a tankless water heater be repaired?
Yes, most problems in a tankless water heater are repairable. Common issues are a clogged inlet filter, a buildup of scale on the heat exchanger, an ignition fault, or a sensor that's failed. A contractor can run the unit's error codes to pinpoint what's wrong before opening anything up. Scale buildup in particular is worth having checked regularly, since it's the main thing that shortens how long these units last.
