Cold nights put the load on your water heater
From December through February, nights in Tuckahoe average 30°F. That cold soaks into the ground and into the water line coming into your house, so your water heater starts every cycle with colder water than it does in summer. A gas water heater answers that by running the burner longer. An electric one keeps the element on longer. That extra run time is what wears on a heating element or a gas control valve over the years.
Power matters too. In Virginia, 22% of households went at least 24 hours without power in 2024, and this county has seen 17 winter storms and 91 damaging wind events over the past ten years. When the power drops, an electric water heater stops heating until it's back, and most units pick up again on their own once it is. If yours doesn't, or the water isn't as hot as it used to be, that's worth having looked at.

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 failing. Water heaters have an inner tank that corrodes over years, and once it starts leaking there, the leak only gets worse. It can also be a loose drain valve or a failed temperature and pressure relief valve, both of which a contractor can check before deciding the tank needs replacing. If the leak is coming from the tank body, the water heater 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 correctly and shuts the gas off even though the pilot lit fine a moment ago. A dirty pilot tube or a draft blowing out the flame can also be the cause. A standing pilot doesn't run on electricity, so a power outage isn't the reason it went out.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, or an error code from a blocked vent are all things a contractor can diagnose and fix. Tankless units also last longer than tank models, so repair is usually worth it unless the heat exchanger itself has failed. A contractor can tell you which one you're dealing with once they've looked at the error code and the unit's history.
