What a Vineland water heater has to handle
Homes here run their heat from October through April, seven months of the year, with winter nights averaging 28°F from December through February. A new water heater goes into a house built for a long, cold season.
Cumberland County has seen 87 damaging wind events and 10 winter storms over the past ten years, and across New Jersey 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. One with electronic ignition will not light until power is back, but it comes back on by itself once it is.
Whatever size and type you install, federal rules set a minimum efficiency for it. That minimum is not one number. It is set by a formula tied to the tank's rated volume, applied separately across four different draw patterns, so two tanks of the same type can face different minimums depending on size.

- How do I know it's time to replace my water heater?
- Age is the first thing to check against what a contractor tells you is typical for your unit's type, since a repair on an old tank is usually just a delay. Rust-colored water from the hot side, rust on the tank itself, or water pooling underneath are signs the tank is failing, and a tank cannot be repaired, only replaced. If it still makes hot water but you run out fast or hear popping and rumbling from the tank, sediment has built up on the bottom, and that only gets worse.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not on whether one is better than the other. A tankless unit heats water only when you open a hot tap, so you don't pay to keep a tank hot all day, and you won't run out of hot water partway through back-to-back showers. It also needs a different gas line and venting than a tank, so switching is a bigger job than a straight swap. A contractor can look at your home's gas supply and venting and tell you what's involved for your house.
- What changes when you install a tankless water heater?
- The unit itself moves from a floor-standing tank to a wall-mounted box, usually much smaller. Gas-fired tankless units draw more gas in the moment they're heating water, so they often need a larger gas line than a tank heater uses. Venting changes too, since tankless units vent differently than a standard tank. None of this is a problem, but it means installation involves more than disconnecting the old tank and connecting the new one, so a contractor needs to see the house to say what's needed.
