What a Manhattan winter 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. A new water heater has to hold up through that whole stretch. It also has to meet the federal minimum efficiency for its size, since that minimum is set separately for each tank volume rather than as one number for every unit.
Power loss is worth planning for too. Across New York, 11% of households went at least 24 hours without power in 2024, and this county has seen 14 winter storms and 32 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water straight through an outage. One with an electric igniter will not light until the power is back, though most units start back up on their own once it is.

A heat pump water heater would save about $620 a year to run in New York compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age, along with how the unit is acting. Water pooling around the base of the tank, water that takes longer to heat or runs out fast, or a rumbling sound as it heats all point to a tank that's failing or has sediment built up inside. Once a tank starts showing these signs, a breakdown can happen without warning, so it's worth having a contractor look at it rather than waiting.
- Should I switch to a tankless water heater?
- It depends on what you're trying to fix. A tankless unit heats water as it flows through, so you're not paying to keep a tank of water hot all day, and it won't run out of hot water partway through a shower. The tradeoff is that a tankless unit usually needs a larger gas line or an electrical upgrade to supply the burst of energy it needs on demand, and a contractor will need to look at your current setup to say what that involves.
- What changes when you install a tankless water heater?
- The unit itself mounts on a wall instead of sitting on the floor. Venting changes too, since tankless units often vent through a wall rather than up through a roof, which gives more flexibility in where the unit goes. Gas-fired tankless units draw more gas at once than a tank does, so the gas line sizing gets checked as part of the install, and electric models may need a dedicated circuit. None of this is guesswork a contractor can do from a distance, it comes down to what's already run to that spot in your home.
