What a Richmond winter asks of a new water heater
Richmond needs heat from October through April, seven months of the year, and winter nights average 30°F from December through February. A water heater runs through all of it without a break, since hot water is a daily need in every season.
Power doesn't always stay on to provide it. Virginia saw 22% of households lose power for 24 hours or more in 2024, and the region has logged 10 winter storms and 15 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. An electric one won't heat water until power is back, though it needs no help to restart once it is.
Federal rules set a minimum efficiency for storage water heaters, but the number isn't fixed. It's set by a formula tied to the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes can face different minimums even though they're the same type of heater.

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?
- Age is the first thing to check, along with how the tank looks and acts day to day. If it's old and you're starting to see rust colored water from the hot side, a damp or rusted spot around the base of the tank, or a pilot that won't stay lit, those are signs the tank itself is failing, not something a repair fixes for good. Replacing it before it fails outright means you choose the timing instead of dealing with a flooded closet or a cold shower with no warning.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your current heater being broken. A tankless unit heats water on demand instead of storing it, so you don't run out partway through back to back showers, and it takes up far less space than a tank. The tradeoff is that switching usually means changes to the gas line, venting, or electrical, so a contractor needs to look at your setup before you know what's involved.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of sitting on the floor, which frees up the space a tank used to take. Because it heats water as it flows through rather than storing a tankful, it often needs a larger gas line or a dedicated electrical circuit to deliver enough energy fast enough. Venting is different too, since tankless units typically vent through a wall rather than up through the roof. A contractor can tell you whether your gas line, electrical panel, and venting can support the switch or need work first.
