What Rochester winters ask of a water heater
Rochester needs heat from October through May, eight months of the year, and winter nights average 20°F from December through February. A water heater works alongside the furnace through that whole stretch, not just in the coldest months.
Power is worth planning around too. Across New York, 11% of households were without power for 24 hours or more in 2024, and the county has logged 18 winter storms and 154 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition, or an electric tank, will sit idle until power comes back, then start up on its own.
Federal efficiency minimums for storage water heaters are not one number. They are 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 when they are the same type. Sizing the new one for your household is part of meeting that standard, not separate from it.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tank water heaters have a working life span, and once a tank passes it, a repair is often just a delay before the next one. Rust colored water from the hot tap, water pooling around the base, or a tank making rumbling or popping sounds all point to the tank itself failing, not a part inside it. A leak at the tank means replacement, since the tank itself can't be repaired. If the unit is old and struggling to keep up with how much hot water the house uses, that's another sign it's reaching the end.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out during a long shower or back to back loads of laundry. It also takes up much less space than a tank. Switching usually means changes to the gas line, venting, or electrical supply, since tankless units draw more power at the moment they fire up. A contractor can look at your home's setup and tell you what that switch would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets made the moment you turn on a tap, instead of pulled from a tank that's been sitting full and heated all day. That means no more running out of hot water, but the unit needs enough gas supply or electrical capacity to heat water fast, which sometimes means upgrading the gas line or adding a dedicated circuit. Venting is different too, since tankless units use a different venting setup than a standard tank. The unit itself mounts on a wall and takes up a fraction of the floor space a tank does.
