Ten months of hot water demand in Williston
Your water heater works September through June here, ten months a year. Winter nights average 4°F, and that cold reaches the tank and the pipes feeding it, not just the furnace.
Power outages happen. Across North Dakota, 7% of households lost power for 24 hours or more in 2024, and the county has seen 23 winter storms and 84 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition needs power to relight. Whatever size and type goes in, federal rules set a minimum efficiency for it, and that minimum is tied to the tank's rated volume, so a larger tank and a smaller one are not held to the same number.

- How do I know it's time to replace my water heater?
- Age is the first thing to check. A tank water heater that's old enough to be near the end of its expected life is a poor candidate for repair, since one fix now just leads to another soon after. Look for rust colored water coming from the hot side, a tank that's damp or weeping at the seams, or a pilot that won't stay lit. Popping or rumbling sounds mean sediment has built up on the bottom of the tank, and that gets worse over time, not better. If you're refilling a bathtub and the hot water runs out partway through, the tank can no longer keep up with the house. Winter nights here average 4 degrees, and a water heater that's already struggling in fall will only fall further behind once the incoming water runs that cold.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your current heater failing. A tankless unit heats water only as it flows through, so you get endless hot water instead of running out partway through a shower. It takes up much less space than a tank, which matters if yours is tucked into a small closet or utility area. What it will not do is deliver hot water faster to a far off fixture, since travel time through the pipe is the same either way. A contractor can look at your gas line, venting, and incoming water temperature and tell you whether your house is a straightforward switch or needs upgrades first.
- 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, every time a tap or shower calls for it. That usually means a larger gas line to the unit, since it draws more fuel for the short time it's firing. Venting is different too, and the unit mounts on a wall rather than sitting on the floor, so the space where your old tank stood opens up. A contractor can size the unit and the gas line for your specific fixtures and usage.
