Eight months of work, then the cold gets in
Your water heater works harder here than the label suggests. October through May, eight months of the year, incoming water runs colder, so the burner or the element has to stay on longer to hit the same temperature. That extra runtime wears on the same parts each time. The thermocouple wears out. The heating element wears out. The gas valve wears out.
Winter nights here average 21°F, so the tank itself sits in a colder space and loses heat faster than it would the rest of the year. Power matters too. Ten percent of Massachusetts households went at least a day without power in 2024, and this county has logged 54 winter storms over the past ten years. An electric water heater with no power makes no hot water at all. A gas one with a standing pilot will keep running through the outage, but if that pilot goes out, nothing comes back on until someone relights it.

A new water heater would cut about $130 a year off hot water for a typical Massachusetts home.

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 from the inside and is starting to fail. Water heaters corrode from the inside out over years of use, and once the tank wall is breached there is no patching it. It could also be a loose drain valve or a fitting at the bottom, which a contractor can check before writing the tank off. If the leak is coming from the tank itself, the unit needs to be replaced, not repaired.
- 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 can't sense the flame properly and shuts the gas off even though the pilot lit a moment ago. A dirty pilot orifice or a draft in the area can also blow the flame out or keep it too small to register. A contractor can test the thermocouple and replace it, which usually solves the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems can be fixed without replacing the whole unit. Common repairs include descaling the heat exchanger, replacing an igniter or flow sensor, or clearing a blocked vent. Because these units run on demand rather than storing water, a fault code on the display usually points a contractor straight to the part that needs attention.
