Ten months of hot water demand, and winters that hit the tank hard
Libby needs heat from September through June, which means the water heater is working nearly all year too, not just in summer months when demand drops elsewhere. Winter nights averaging 19°F put real strain on a tank, especially if it sits in a garage or basement that gets cold.
Montana households lost power for 24 hours or more at a rate of 18% in 2024, and Lincoln County has seen 31 winter storms and 23 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on electronic ignition will not, until power comes back. New units also have to meet the federal efficiency minimum, which is set by tank size and how the household draws hot water, so the right minimum for a small tank is not the same as for a large one.

- How do I know it's time to replace my water heater?
- The clearest sign is water that won't stay hot, or runs out faster than it used to. Rust-colored water, a tank that's rusting or bulging on the outside, or water pooling underneath are all reasons to stop repairing it and replace it. Once a tank starts failing like this, another repair usually just buys a little time before the next one. If yours is old and giving you trouble, replacing it makes more sense than patching it again.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank has failed. A tankless unit heats water as it flows through, so you don't run out of hot water partway through a shower, and it doesn't sit there heating a tank of water all day when nobody's using it. It costs more to install than a tank does, and it needs a different setup, gas line, venting, sometimes electrical, so a contractor needs to look at your house before you decide either way.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start making it on demand, only when a faucet or appliance calls for it. That usually means new venting made for a tankless unit, and often a bigger gas line since it draws more gas in the moment than a tank does. The unit itself mounts on a wall instead of taking up floor space, which matters if you're tight on room. A contractor will need to check your gas line and venting against what the new unit requires before installing it.
