Le Mars asks a lot of a water heater
Winter nights here average 13°F from December through February, and groundwater coming into the tank starts out cold. A water heater in Plymouth County works harder to bring that water up to temperature than one in a milder state, and it does that work eight months of the year, October through May.
Power loss is worth planning for too. In Iowa, 15 percent of households went at least 24 hours without power in 2024, and the county has seen 26 winter storms and 51 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage. One with electronic ignition needs power to fire, same as most electric tanks. When you're choosing a replacement, it's worth asking which kind you're getting and what happens to it when the lights go out.

- How do I know it's time to replace my water heater?
- If your water heater is old and starting to act up, that's your sign to plan for a new one rather than wait for it to fail. Rust colored water from the hot tap, a tank that's damp or rusted at the base, or water that never gets fully hot mean the tank itself is failing, not just a part inside it. A leak at the tank means replacement, since the tank isn't something a contractor can patch. Get it looked at before it fails outright and leaves you without hot water in the middle of winter.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out partway through back to back showers, but it needs enough gas supply or electrical capacity to fire at that rate, and the venting has to be run to match. A contractor can look at your gas line, electrical panel, and where the unit would go and tell you whether your house is a straightforward switch or needs upgrades first.
- 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, so there's no tank sitting full and losing heat while it waits to be used. The unit itself is much smaller and usually mounts on a wall instead of taking up floor space. Venting is different from a tank model, and the gas or electrical service to the unit often needs to be upsized to handle the higher demand at the moment of use. Installing one is a bigger job than swapping a tank for a tank, and it still needs a permit and inspection like any water heater replacement here.
