Water heaters in Fremont County work through a long, cold season
Winter nights here average 10°F from December through February, and homes need heat from September through June, ten months a year. A water heater has to hold a full tank at temperature through all of that, night after night, in cold that goes on for months.
Power is part of the picture too. Wyoming saw 8% of households go at least 24 hours without power in 2024, and Fremont County has logged 364 winter storms and 342 damaging wind events over the past ten years. A tank-style heater with a standing pilot keeps working through an outage, while one with electronic ignition will not. Whatever goes in has to meet the federal minimum efficiency for its size and type, a standard set separately for each tank volume and draw pattern rather than as one number for all.

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 water that no longer gets consistently hot, or a tank that's leaking from the bottom. Rust colored water from the hot tap, a popping or rumbling sound as it heats, or water pooling around the base all point to the tank itself failing, and that's not something a repair fixes. If the heater is older and starting to act up, a repair may just delay a replacement that's already coming. A contractor can check the tank and give you a straight answer either way.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water, not on your current heater being broken. A tankless unit heats water on demand instead of storing it, so you don't run out during back to back showers or a full tub. What it won't do is make hot water arrive faster at the tap, since that's about the length of your pipes, not the heater. A contractor can look at your gas line and venting, since tankless units often need different setups than a tank did.
- What changes when you install a tankless water heater?
- The biggest change is where the unit goes and what feeds it. A tankless heater mounts on a wall instead of taking up floor space, and it needs its own venting sized for the unit, which is different from a tank's vent. Gas fired tankless units draw more gas at once than a tank heater does, so the gas line often needs to be checked to see if it can keep up. Electric tankless units draw enough power that the electrical panel needs the same kind of check. None of this means your home can't take one, it just means a contractor needs to look at the gas line, venting and panel before install, not just swap the heater itself.
