Ten months of heating in Hot Springs County
Winter nights here average 12°F from December through February, and homes need heat from September through June. A new water heater installed here has to hold up through most of the year, not just a few winter weeks.
Storms are part of the picture too. This county has logged 66 winter storms and 68 damaging wind events over the past ten years, and 8% of Wyoming households went at least 24 hours without power in 2024. That is worth weighing when you choose between a tank that needs power to fire and a standing pilot that does not. Federal efficiency minimums for storage water heaters are not a single number either. They scale with the tank's rated volume, so the minimum that applies depends on the size you install.

A heat pump water heater would save about $300 a year to run in Wyoming compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age. Most tank water heaters last between eight and twelve years, and once you're past that, a single failure isn't worth fixing. Look for rust colored water, a tank that's rusting on the outside, water pooling underneath it, or a unit that can't keep up with hot water like it used to. If you're already calling someone out for repairs more than once a year, replacement usually costs less over time than keeps patching it. A tank that fails outright, rather than just aging, will often show a slow leak at the base first, so check there when you're near it.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not just whether it's newer technology. Tankless units heat water on demand instead of storing it, so you get a steady supply as long as the unit can keep up with your fixtures running at once. They also tend to last longer than tank models and take up less space. The tradeoff is that they cost more upfront to buy and install, especially if your home's gas line or electrical service needs upgrading to run one. A contractor can look at your home's setup and tell you whether the switch makes sense for your fixtures and your budget.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as it flows through the unit. That means no more running out of hot water partway through a shower, but it also means the unit has a maximum flow rate, so two showers and a dishwasher running together can still stretch it thin. Installation often requires larger gas lines or dedicated electrical circuits than a tank model used, plus new venting since tankless units vent differently. The unit itself mounts on a wall instead of sitting on the floor, which frees up space but means it has to go somewhere with access to those gas, electric, and venting connections. A contractor evaluating your home can tell you what's already in place and what would need to change.
