Polson winters set the bar for a new water heater
Homes here need heat from September through June, ten months a year. On winter nights that average 20°F, a water heater is working through a long cold season, not just a few weeks of it.
Power is part of the picture too. Lake County has logged 125 winter storms and 57 damaging wind events over the past ten years, and 18% of Montana households went at least 24 hours without power in 2024. A gas water heater with a standing pilot keeps making hot water through an outage. An electric one won't, and will need to be restarted once power is back. Whatever gets installed has to meet the federal minimum efficiency for its size and type, a number that changes with the tank's rated volume rather than one figure for every unit.

A heat pump water heater would save about $270 a year to run in Montana compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Look at what the tank is telling you, not just its age. Rust-colored water from the hot tap, a tank that's damp or weeping at the base, or water that never gets fully hot anymore are all signs the tank itself is failing rather than one part inside it. A leaking tank won't be patched, it needs to be replaced, so if you see water pooling underneath, that's your answer right there. A contractor can look at the tank and tell you whether a repair still makes sense or whether you're past that point.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on your current unit's condition. A tankless heater gives you hot water on demand instead of storing a set amount, so you won't run out partway through back-to-back showers the way you can with a tank. It also takes up much less space than a storage tank. Switching means changing the gas line, venting, or electrical supply to match what the tankless unit needs, so a contractor will need to look at your setup to say what that involves in your home.
- What changes when you install a tankless water heater?
- The unit itself is smaller and usually goes on a wall instead of taking up floor space. It needs its own venting, sized for the tankless heater rather than whatever vented the old tank, and gas units often need a larger gas line to supply enough fuel on demand. Electric tankless units draw a lot of power for a short burst, which can mean upgrading the circuit. None of this is guesswork on the contractor's part, it comes down to what your home already has in place and what the new unit requires.
