What Jersey City asks of a new water heater
Winter nights here average 28°F from December through February, and homes need heat from October through April, seven months of the year. Cold groundwater during those months means an incoming water heater has to work harder to reach the same set temperature than it would in summer.
Power outages happen here. Statewide, 11% of households went at least 24 hours without power in 2024, and Hudson County has logged 16 winter storms and 35 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on electric ignition does not, until the power is back.
Whatever size and type you choose, it has to meet the federal minimum efficiency set for that tank. That minimum is not one number for all water heaters. It is set separately by size and by draw pattern, so a small tank and a large tank of the same type can face different requirements.

A heat pump water heater would save about $580 a year to run in New Jersey 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, and a contractor can tell you what your unit's rated life is. Beyond that, look for rust-colored water, a tank that's damp or sweating around the base, or water that never gets as hot as it used to. If the tank itself is leaking rather than a fitting or valve, that's not a repair, that's a replacement, because a leaking tank only gets worse. Once you see rust or moisture at the base, it's worth having a contractor look before it fails outright and water reaches the floor around it.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on where you live. A tankless unit heats water as it flows through rather than storing it, so you don't run out of hot water partway through a shower with someone else running the dishwasher. It also takes up much less space than a tank. What it won't do is turn on during a power outage any more than a standard electric or powered-vent tank would, since it still needs electricity to run its controls and ignition. A contractor can walk through your gas line, venting, and water use with you to say whether it's the right move for your house.
- What changes when you install a tankless water heater?
- The biggest change is what's on the wall instead of what's on the floor. A tankless unit mounts to the wall and takes up a fraction of the space a tank does, which matters if it's coming out of a closet or a tight utility room. It usually needs its own venting run to the outside, sized differently than a tank's, and often needs a gas line rated for a higher flow rate to heat water fast enough on demand. Some homes also need an upgraded electrical circuit for the unit's controls. A contractor will check your existing gas line, venting path, and electrical setup before install to see what needs to change.
