Ten months of heat means ten months of hot water demand
Thompson Falls needs heat from September through June, ten months of the year, and a water heater is part of that load the whole time. Winter nights average 20°F, which means the water coming into the tank is as cold as it gets for most of the year, not just for a few weeks.
Power is the other piece. Sanders County has recorded 128 winter storms and 60 damaging wind events over the past ten years, and across Montana, 18% of households went at least 24 hours without power in 2024. Most storage water heaters come back on by themselves once power is restored. A gas unit with a standing pilot does not need power to keep the pilot lit, but anything with electronic ignition will need it relit by hand. Federal efficiency minimums for storage water heaters are set by a formula tied to the tank's rated volume and draw pattern, so the number that applies depends on the size and type of unit going in.

- How do I know it's time to replace my water heater?
- The clearest sign is age combined with trouble. Most tank water heaters last about 10 years, and once you're past that, a leak, rusty water, or a pilot or igniter that keeps failing means it's time rather than time for another repair. Water pooling at the base of the tank is the one sign that means stop waiting. That's the tank itself failing, not a part inside it, and it won't get better. Homes here need heat from September through June, so a tank that's already showing its age is one more thing to have working through those months.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. A tankless unit heats water as it flows through rather than storing it, so you get continuous hot water instead of running out partway through a shower. It also takes up much less space than a tank. What it doesn't do is work during a power outage, since it still needs electricity to run even on a gas model. With 18% of Montana households losing power for a day or more in 2024, that's worth weighing against a standing pilot tank, which keeps producing hot water with no power at all.
- What changes when you install a tankless water heater?
- The biggest change is what's on your wall instead of what's on your floor. A tankless unit mounts up, not down, and needs venting sized for it, gas line capacity checked against its higher draw, and often an electrical connection for its ignition and controls. A contractor will look at your home's existing gas and vent lines to size the job correctly, since a tankless unit that outpaces what's already there won't perform the way it's supposed to. None of this is a simple swap in the same spot as the old tank.
