What Laconia winters ask of a water heater
Winter nights here average 14°F from December through February, and the water entering your tank is just as cold. Heating that water to temperature takes more work in that cold, and your house needs heat from September through May, nine months a year, so the water heater is rarely the only appliance drawing on your system.
Power loss is part of the picture too. Statewide, 22% of households went at least 24 hours without power in 2024, and the region has logged 44 winter storms and 38 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage. One with electronic ignition, and any electric tank, will not fire until power is back. Whichever type you choose, it has to meet the federal minimum efficiency set for its size, since the standard is written separately for each tank volume rather than as one number across the board.

- How do I know it's time to replace my water heater?
- Watch for water that never quite gets hot, rust colored water from the hot tap, or water pooling at the base of the tank. A tank that's leaking from the tank itself, not a loose fitting, is done. Most tank water heaters last a decade or so, and once one starts needing repairs it tends to need them again soon after. If yours is that age and giving you trouble, a contractor can tell you whether it's worth fixing or worth replacing, especially with 14 degree nights here from December through February putting real demand on it.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your current tank failing. A tankless unit heats water on demand instead of storing it, so you don't run out of hot water partway through a shower with the dishwasher running. It won't sit there losing heat overnight the way a stored tank does. Whether it makes sense for your house depends on your gas line, venting, and water use, so it's worth having a contractor look at the specifics before deciding.
- What changes when you install a tankless water heater?
- The biggest change is that hot water becomes limited by flow rate instead of by how much is stored. A tankless unit can supply hot water as long as you're drawing it, but if several fixtures run at once it may not keep up with all of them at full temperature. Installation often calls for a larger gas line or different venting than a tank used, since the burner has to heat water fast rather than slowly over time. A contractor can look at your gas supply and venting to say what's needed for your house specifically.
