What a Flemington winter asks of a new water heater
Water heaters in Hunterdon County work against cold groundwater eight months of the year, October through May, with winter nights averaging 23°F. The incoming water is colder for longer here, so the tank or unit works harder to bring it up to temperature than it would somewhere with a shorter, milder winter.
Power is part of the picture too. About 11% of New Jersey households lost power for 24 hours or more in 2024, and the county has logged 20 winter storms and 154 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One that relies on electronic ignition does not, until the power is back.
Any new storage water heater installed today has to meet the federal minimum efficiency for its type and tank size. That minimum is set separately for each size and draw pattern, so the exact number depends on the tank you need, not just the brand or fuel type.

- 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 of somewhere around a decade, and once a unit is old, a repair is just delaying a replacement you will pay for anyway. Rust colored water from the hot tap, a tank rusting on the outside, or water pooling underneath are signs the tank itself is failing, and a failing tank cannot be repaired. If it is still running but taking longer to heat, or not keeping up like it used to, a contractor can tell you whether that is the heating element, sediment buildup, or the tank reaching the end of its life.
- 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 you use it instead of storing it, so you do not run out of hot water partway through a shower or a load of dishes. It also takes up less space than a tank, which matters if yours is in a closet or a tight utility area. The tradeoff is that a tankless unit usually needs different gas or electrical service than a tank did, which is why a contractor needs to look at your home's setup before you decide.
- What changes when you install a tankless water heater?
- The biggest change is that the hot water does not run out. A tank holds a fixed amount and once it is used up you wait for it to reheat, but a tankless unit heats water on demand as long as you are running the tap. Because it works differently, it often needs a larger gas line or a dedicated electrical circuit than the old tank used, along with new venting. It also mounts on the wall instead of sitting on the floor, which frees up the space the old tank used to take.
