Cold winters put a real load on your water heater
Barnstable County homes need heat eight months a year, October through May, and winter nights average 26°F from December through February. The colder the water coming into the tank, the harder the burner or the heating element has to work to bring it up to temperature. That extra run time wears on the same parts that fail everywhere else, but sooner.
The county has seen 14 winter storms and 249 damaging wind events over the past ten years, and across Massachusetts one household in ten went at least 24 hours without power in 2024. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition or an electric tank will not fire back up on its own once power drops, and you will notice hot water not coming back until it is restored.

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 over years of holding hot water, and once the tank wall gives way, no part or seal can fix it. It can also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done. 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 shuts off gas to the pilot even though the flame is still lit, and the pilot goes out. A dirty pilot tube or a draft in the area can also blow it out. A standing pilot doesn't use any power to stay lit, so a power outage would not cause this.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a clogged inlet filter, a buildup of scale on the heat exchanger, or an error code pointing to a sensor or igniter. A contractor can diagnose which part is failing and replace it rather than the whole unit in most cases.
