Salem County asks a lot of a water heater
Winter nights here average 28°F from December through February, and homes run their heat from October through April, seven months of the year. A new water heater has to work through that whole stretch, pulling in cold water and bringing it up to temperature night after night.
Power doesn't always stay on through it. Across New Jersey, 11% of households lost power for 24 hours or more in 2024, and this county has logged 12 winter storms and 73 damaging wind events over the past ten years. That's worth thinking about when you're choosing a new unit, since some recover on their own once power is back and some don't. And with storage tanks, the federal efficiency minimum isn't one number. It's set by a formula tied to the tank's size, so the minimum for your replacement depends on the gallons it holds.

- How do I know it's time to replace my water heater?
- Look at the age of the tank first. Most tank water heaters have a working life span, and once a unit is well past it, a repair is just delaying the next one. Rust colored water from the hot side, rust on the tank itself, or water pooling underneath all point to the tank failing, and a leaking tank can't be repaired. If it still makes hot water but runs out fast or pops and rumbles, sediment has built up in the bottom, and that gets worse over time, not better. A contractor can tell you whether what you're seeing is normal wear or the tank giving out.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. Tankless units heat water on demand instead of storing it, so you don't run out during a long shower or back to back loads of laundry, and they don't sit there keeping a tank of water hot all day. They also take up much less space, which matters in a tight utility closet or basement. Switching usually means changes to the gas line, venting, or electrical to match what the new unit needs, so it's worth having a contractor look at your setup before deciding. Winters here bring cold groundwater along with cold air, and that affects what size tankless unit the house actually needs.
- What changes when you install a tankless water heater?
- The water heater itself is the smaller part of the job. Tankless units often need a larger gas line than the old tank did, because they fire at a higher rate to heat water instantly rather than gradually. Venting is different too, since most tankless models use sealed venting through PVC or stainless steel rather than the metal flue a tank used. Some installations also call for an upgraded electrical connection for the unit's controls. A contractor will check the gas line, vent path, and electrical before quoting the job, since what's already in place determines how much has to change.
