What Lisbon winters ask of a water heater
Groundwater coming into your house here starts cold, and in the winter months it starts colder still, with nights averaging 5°F from December through February. A new water heater has to bring that water up to temperature every time you run a tap, and the colder it comes in, the harder the unit works to do it. With heat needed in the house nine months of the year, September through May, the water heater is rarely working from a warm start.
Power is part of the picture too. Across North Dakota, 7% of households lost power for 24 hours or more in 2024, and Ransom County has logged 54 winter storms and 46 damaging wind events over the past ten years. If you go with a standard tank, it will not run without power, and a gas unit with a standing pilot is the one that keeps working through an outage. Whatever size and type you choose, it has to meet the federal minimum efficiency for its tank volume, which is set separately for each size rather than as one number across the board.

A heat pump water heater would save about $260 a year to run in North Dakota compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Look at the age first. If your water heater is old enough that you're not sure it'll make it through another winter, that's already a sign to start planning, since a failure here means no hot water in the middle of a cold stretch. Rust colored water, a tank that's rusting on the outside, or water pooling underneath means the tank itself is failing, and that can't be fixed. If it's making a rumbling or popping noise, sediment has built up on the bottom, and that speeds up the wear on the tank.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not just whether it saves space. A tankless unit heats water only when you run a tap, so it doesn't hold a reserve that can run out during a long shower, and it doesn't sit there losing heat when no one's using hot water. It also needs a different gas line size or electrical circuit than a tank in many homes, so the swap isn't a straight one for one. A contractor can look at your gas line, your vent, and your water use and tell you whether it makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is the gas line. Tankless units need more gas flow than a tank heater to heat water fast, so the existing line often has to be resized. Venting changes too, since a tankless unit vents differently than a tank and usually needs its own dedicated vent run. Some homes also need an electrical circuit added for the unit's controls. None of this is unusual, but it means the installation involves more than swapping one box for another, and a contractor needs to see the house to say what's needed.
