Cold winters put a strain on your water heater
Winter nights in Claremont average 13°F from December through February, and the ground and pipes feeding your water heater run cold for months at a time. That means your water heater works harder to bring water up to temperature, and it runs that hard from September through May, nine months of the year.
Power loss adds to the problem. Nearly a quarter of New Hampshire households went at least a day without power in 2024, and Sullivan County has seen 37 winter storms and 58 damaging wind events over the past ten years. A gas water heater with an electronic ignition will not light without power, and when the power comes back on, some units need to be relit by hand. If your water heater is electric, an outage stops it cold until service returns.

- Why is my water heater leaking from the bottom?
- Most of the time this means the tank itself has rusted through, and once that happens the tank needs to be replaced, not repaired. But leaks at the bottom can also come from a loose drain valve or a fitting that has failed, and those can often be fixed without replacing the tank. A contractor can check the valve and fittings first before deciding the tank is the problem.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn out thermocouple, the part that senses the pilot flame and keeps gas flowing to it. A draft near the unit or a problem with the gas supply reaching the pilot can also cause it to go out. A contractor can test the thermocouple and check for drafts or gas flow issues to find which one it is.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired, including a failed igniter, a bad flow sensor, or mineral buildup on the heat exchanger. A contractor can flush the unit or replace the failed part depending on what's found.
