Berlin winters put a real load on a water heater
Winter nights here average 8°F from December through February, and homes in this county need heat for ten months of the year, September through June. A water heater doesn't get a break when the furnace is running that long. It's drawing cold water into the tank and holding it at temperature through the same months the rest of the house is fighting the cold.
Power loss is part of the picture too. Nearly a quarter of New Hampshire households went at least 24 hours without power in 2024, and the county has seen 93 winter storms and 62 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps running through an outage. One with an electric igniter will not light until the power is back on. Whatever you install, it also has to meet the federal minimum efficiency for its size and type, since the rule is set by the tank's rated volume rather than one number for every unit.

- How do I know it's time to replace my water heater?
- Water pooling at the base of the tank means it's leaking, and that means replacement, not repair. Rusty water from the hot tap, a tank that's making popping or rumbling noises, or water that won't get hot anymore are all signs the tank is failing. Age matters too, so if yours has been in the house a long time and is starting to act up, it's worth having a contractor look at it before it fails on its own and floods the area around it.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water on demand instead of storing it, so you don't run out of hot water partway through back to back showers. It also tends to last longer than a tank. Against that, a tankless unit usually needs a larger gas line or an electrical upgrade to run, since it has to heat water fast rather than slowly over time. A contractor can look at your gas line, venting, and electrical panel and tell you what switching would actually involve in your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water no longer runs out. A tank holds a fixed amount and once it's used up you wait for it to reheat. A tankless unit heats water as it passes through, so a long shower doesn't run the house out of hot water. The install itself often changes more than the water heater does. Gas-fired tankless units need enough gas flow to fire the burner, and that can mean a larger gas line than the tank version used. Venting is different too, since tankless units vent differently than most tank units. A contractor can tell you what your house needs to make the switch.
