Cold winters put your water heater to work
From October through May your water heater is heating groundwater that started out closer to 28°F outside. It runs longer to make up that difference, and the burner or heating element cycles more to hold a set temperature. That extra cycling is what wears out an igniter or an element years before it should.
Hempstead also loses power sometimes. New York saw 11% of households go at least 24 hours without it in 2024, and the county has logged 37 winter storms and 143 damaging wind events over the last ten years. Most water heaters come back on by themselves once power returns, but a unit that was already struggling can fail right at that moment, and you find out when the water runs cold or never gets hot at all.

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 bottom leaks come from the tank itself rusting through from the inside, and once that happens the tank has to be replaced, not patched. The other common cause is a fitting or drain valve that has loosened or corroded, which can sometimes be repaired. A pool of water under the tank can also come from condensation or from the temperature and pressure relief valve doing its job, so the actual source needs to be traced before you know which one you have. A contractor can tell within a few minutes whether it's the tank or something around it.
- Why won't the pilot light on my water heater stay lit?
- This usually means the thermocouple has worn out and can no longer sense that the pilot is lit, so it shuts the gas off as a safety measure. It can also mean the pilot orifice is clogged or there's a draft in the area reaching the flame. A thermocouple is a low-cost part to replace and is one of the most common water heater repairs there is. If the pilot won't stay lit even after a fresh thermocouple, the gas control valve itself may need to be replaced.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairs, not replacements. A failing igniter, a blocked flow sensor, a scaled heat exchanger, or an error code tied to a specific sensor can all be diagnosed and fixed without replacing the unit. Tankless units also depend on clean intake and exhaust venting, so a blockage there can cause the same symptoms as a part failure. A contractor can pull the error code and confirm which part is at fault before recommending a repair.
