Morris County winters are hard on a water heater
Groundwater coming into the tank is cold for eight months here, October through May, and colder still on nights that average 22°F. The burner or the element has to work harder and longer to bring it up to temperature, and that extra runtime wears on the thermostat and the heating element or gas valve years before they'd otherwise quit.
Morris County has seen 188 damaging wind events and 20 winter storms over the past ten years, and 11% of New Jersey households lost power for a full day or more in 2024. A gas water heater with a standing pilot will keep running through an outage, but most electric units and any with electronic ignition go cold the moment the power does, and come back on their own once it's restored. If yours doesn't, or if the water runs lukewarm after an outage, that's worth a look.

A new water heater would cut about $90 a year off hot water for a typical New Jersey home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself has corroded through from the inside and is failing. Water pools at the base because that is the lowest point it can reach. It can also be the drain valve or a fitting that has loosened, which a contractor can check before assuming the tank is the problem. Once a tank is actually leaking, it needs to be replaced, not patched, because the corrosion will keep spreading.
- Why won't the pilot light on my water heater stay lit?
- This usually means the thermocouple has worn out and can no longer sense that the pilot is lit, so it shuts the gas off. It can also be a draft blowing the flame out, or a clogged pilot orifice restricting gas flow. A thermocouple is a cheap part to replace and is the first thing a contractor will test. If the pilot relights and holds when you bypass the safety switch, that confirms the thermocouple is the issue.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable without replacing the whole unit. Mineral buildup on the heat exchanger is common and is cleared by flushing the system with a descaling solution. Ignition failures, error codes, and sensor problems usually point to a single part that can be replaced. A contractor can read the unit's error code to know exactly what's failing before opening it up.
