What a new water heater here needs to handle
Hampton winters aren't extreme, but homes here still run heat six months a year, November through April, with nighttime lows averaging 34°F from December through February. A water heater in that stretch works through cooler incoming water than it sees the rest of the year.
Power is the other piece to plan for. Nearly a quarter of Virginia households went at least 24 hours without power in 2024, and the area has logged 26 damaging wind events and 5 winter storms over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One with electric ignition won't light until power is back. Whatever type goes in, it has to meet the federal minimum efficiency set for its tank size, and that minimum is figured separately for each size and draw pattern, so the number that applies depends on the unit being installed.

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?
- The clearest sign is water pooling around the base of the tank. Once the tank itself is leaking, it's rusting through from the inside, and that damage doesn't stop. Rust-colored water from the hot tap, a tank that's making rumbling or popping noises, or a unit that's gotten old are all reasons to have it looked at before it fails on its own. A tank that fails outright usually does it without warning, and going without hot water for even a day matters more when winter nights here average 34 degrees.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just what you have now. A tankless unit heats water on demand instead of storing it, so you get a steady supply as long as you run it. It won't work with your existing setup as is. Tankless units typically need a gas line sized for their higher input or a dedicated electrical circuit, plus venting built for their exhaust, so switching means more than swapping one box for another. A contractor can tell you what your house would need to make the switch.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, which is the first thing most people notice. Behind that wall, the connections change too. Gas-fired tankless units draw more gas at once than a tank does, so the gas line often needs to be resized, and the venting is different from what a tank uses. Electric tankless units instead need a circuit built for their draw. None of this is a swap you'd do on your own. A contractor can walk the house and say exactly what needs to change for your setup.
