What a water heater in Suffolk County has to handle
Winter nights here average 23°F from December through February, and homes need heat running October through May, eight months of the year. A new water heater has to hold up through all of it, keeping hot water flowing whether it's feeding a shower or backing up the heating system.
Power doesn't always stay on through a storm. The state saw 10% of households lose power for 24 hours or more in 2024, and the county has logged 22 winter storms and 140 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One with electric ignition won't light until the power is back, though most start up on their own once it does. Whatever you install, it has to meet the federal minimum efficiency set for its size, since the standard is applied separately by tank volume rather than as one number for every heater.

- How do I know it's time to replace my water heater?
- If your water heater is old and giving you trouble, that's usually reason enough to think about replacing it rather than repairing it again. Rusty water from the hot tap, a tank that's rusting on the outside, or water pooling underneath are signs the tank itself is failing, and a leaking tank cannot be repaired. Popping or rumbling sounds mean sediment has built up on the bottom, which makes the unit work harder and can shorten what's left of its life. If you're rebuilding the same part more than once, or the water isn't getting as hot as it used to, a contractor can tell you whether it's worth fixing or time to replace it.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on the fact that your current one is old. A tankless unit heats water only when you open a hot tap, so it doesn't run a tank of water hot all day, and it won't run out partway through back to back showers. What it doesn't do is deliver more gallons per minute than it's rated for, so a house that regularly runs two showers and a washing machine at once needs a unit sized for that. A contractor can look at your fixtures and your gas or electric supply and tell you whether tankless makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand, so there's no tank sitting full and hot all day. Tankless units also need more gas flow or electrical capacity than a tank heater in the same spot, so the gas line or the electrical circuit sometimes has to be upsized. Venting is different too, since a gas tankless unit typically vents through the sidewall rather than up through the roof. Because of that, installation is more involved than a straight tank swap, and a contractor will need to look at the gas line, electrical panel, and venting path in your house before pricing the job.
