A new water heater here works through a long, cold winter
Winter nights in Anaconda-Deer Lodge County average 13°F from December through February, and homes here need heat all year round. A water heater does its own version of that work, pulling in cold groundwater and bringing it up to temperature every day, all year, with no break in summer.
The county has seen 49 winter storms and 15 damaging wind events over the past ten years, and across Montana 18% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep working through an outage. One that relies on an electronic igniter will not light until the power is back. Whatever model goes in, it also has to meet the federal minimum efficiency for its size, since the standard is set separately for each tank volume rather than as one number for every unit.

A heat pump water heater would save about $400 a year to run in Montana compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Age is the first thing to check, since tank water heaters have a limited service life and start failing more often as they near the end of it. If yours is older and you're seeing rust-colored water, a tank that's damp or rusting around the base, or water that doesn't get as hot as it used to, those point to the tank itself wearing out rather than a part that can be swapped. A tank that's actually leaking from the body, not a fitting, needs replacing, not repair. If you're already calling someone out for repeated repairs on an older unit, ask them to look at the whole picture rather than fix the same issue again.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on age or a repair you're facing. A tankless unit heats water as it flows through rather than storing it, so you don't run out of hot water partway through a shower the way you can with a tank. It also takes up less space and doesn't sit there losing heat from a tank of standing water when nothing is running. Against that, a tankless system usually means changes to the gas line, venting, or electrical supply to handle the higher demand, so it's not a straight swap. A contractor can look at your current setup and tell you what switching would actually involve in your house.
- What changes when you install a tankless water heater?
- The water heater itself gets smaller, but what feeds it usually has to get bigger. A tankless unit needs more gas flow or more electrical capacity in the moment it's heating water, since it's not drawing on a stored reserve, so the gas line or breaker may need to be upsized. Venting is different too, since tankless units typically vent through a different type of pipe than a standard tank. None of this means installation is harder, just that it involves more than setting a new unit where the old one stood, which is why a contractor needs to see the existing setup before saying what's needed.
