What Chesapeake winters mean for a new water heater
Winter nights here average 33°F from December through February, and homes run their heat from November through April. A water heater has to work harder those six months, since the water coming into the tank is colder for longer.
Power is part of the picture too. Statewide, 22% of households in Virginia went at least 24 hours without power in 2024, and Chesapeake has seen 8 winter storms and 58 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electric ignition does not, until the power comes back. Either way, the unit installed should match what the house can count on.

A heat pump water heater would save about $320 a year to run in Virginia compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Water that no longer gets hot, or runs out fast, is the clearest sign. Rust colored water, a tank that's rusting or sweating around the base, or a popping sound when it heats are others. Most tank water heaters last around 8 to 10 years, so age matters too, even if it's still working. If you're not sure whether yours is failing or just aging, a contractor can check the tank and the anode rod and tell you which one it is.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current one is failing. A tankless unit heats water as it flows through, so you don't run out partway through a shower with several people in the house. It takes up less space than a tank and doesn't lose heat sitting full of hot water all day. The trade-off is that a tankless unit needs its own venting and gas or electric supply sized for it, which is why a contractor has to look at your specific setup before you can decide.
- What changes when you install a tankless water heater?
- The biggest change is that you get hot water on demand instead of drawing from a tank that has to reheat between uses. That means no more running out of hot water, but the unit has to be sized to your home's peak flow rate, how many fixtures might run hot water at once. The venting is different too, tankless units typically vent through a small pipe rather than a standard flue, and gas units need a properly sized gas line. A contractor will check your home's gas or electric capacity and venting path before installing one, since those requirements are specific to the unit and the house.
