What Buffalo winters ask of a new water heater
Winter nights here average 19°F from December through February, and the water coming into the tank is just as cold. A new water heater has to bring that cold water up to temperature for eight months of the year, October through May, which is most of it.
Power doesn't always stay on through that stretch. Erie County has logged 45 winter storms and 241 damaging wind events over the last ten years, and across New York, 11% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps working through an outage, since it needs no power to stay lit. Whichever type goes in, the federal minimum efficiency it has to meet is set by the tank's rated volume, so the number that applies depends on the size you choose.

A heat pump water heater would save about $620 a year to run in New York 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. Most tank water heaters last about a decade, and once you're near that mark, a repair is just a delay on a replacement you'll need anyway. Rust-colored water, a tank that's damp or rusting at the seams, or water pooling underneath means the tank itself is failing, and that's not something a part swap fixes. If it's still making hot water but not enough of it, or it's making popping and rumbling sounds, sediment has built up on the bottom of the tank and the unit is working harder than it should. A contractor can tell you whether what you're seeing is a fixable problem or the tank telling you it's done.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. A tankless unit heats water as it flows through rather than storing and reheating it, so it doesn't run out partway through back-to-back showers the way a tank can. It also takes up much less space, since there's no tank to fit somewhere. What it won't do is make hot water appear instantly at the faucet. The wait for hot water depends on the distance from the unit to that faucet, same as with a tank. If your house loses power for stretches, know that most tankless units need electricity to run even on gas models, so a power outage means no hot water either way unless the unit has battery backup.
- What changes when you install a tankless water heater?
- The biggest change is that hot water becomes a matter of demand, not supply. There's no tank to run down, so a shower ending isn't about the reserve emptying anymore. Installation itself is more involved than swapping one tank for another. A gas tankless unit usually needs a larger gas line to supply enough fuel for the burner to heat water on the fly, and venting requirements are different from a standard tank. Electric tankless units often call for more electrical capacity than the house already has run to that spot. A contractor will look at your gas line, venting, and electrical setup to size the unit correctly and tell you what needs to change to support it.
