Claremont winters set the terms for your new water heater

Nights here average 13°F from December through February, and the house calls for heat nine months of the year, September through May. A water heater in that kind of house works harder for longer, since the pipes feeding it and the space around it stay cold most of the year.

Power matters too. Close to a quarter of New Hampshire households went at least a full day without power in 2024, and the county has seen 37 winter storms and 58 damaging wind events over the past ten years. That is worth knowing before you pick a fuel type and a recovery method. Whatever you install, it will need to meet the federal efficiency minimum for its size and type, since the standard is set separately for each tank volume rather than as one number for every water heater.

How do I know it's time to replace my water heater?
Look at the age first. Once a tank water heater gets old, the tank itself becomes more likely to fail than any part inside it. Rust colored water from the hot tap, a tank that ticks or rumbles as it heats, or water pooling at its base are all signs the tank is going, not something that gets fixed. If you are weighing your options, a tank water heater with a standing pilot needs no power to run, so it will keep giving you hot water through a winter outage, and outages are not rare here.
Should I switch to a tankless water heater?
It depends on what you want from it, not just what it costs to run. A tankless unit heats water as you use it instead of storing a tankful, so you do not run out during a long shower and it takes up far less space than a tank. It also needs power to fire, so during an outage it will not produce hot water unless the house has a backup power source, and close to a quarter of households in New Hampshire went at least a full day without power last year. A contractor can look at the house and say whether the gas line and venting can support one.
What changes when you install a tankless water heater?
The biggest change is that hot water gets made on demand instead of stored ahead of time. That means no standby heat loss from a tank sitting full of hot water all day, and a nearly endless supply since it is not limited by tank size. It also means the unit depends on power and, for gas models, often a larger gas line and different venting than the old tank used. A contractor will need to check the existing gas and electric supply to the house before sizing the new unit.
