What a Muscatine County winter asks of your water heater
Homes here need heat from October through May, eight months a year, and winter nights average 17°F. Cold weather like that means a water heater is working most of the year, not just a few months.
Storms are part of the picture too. The ten years from 2015 to 2024 brought 25 winter storms and 59 damaging wind events to this area, and in 2024, 15% of Iowa households lost power for 24 hours or more at some point. If your water heater runs on electricity, an outage means no hot water until the power is back, and it comes back on its own once it is. A gas unit with a standing pilot keeps working through the outage.
When you install a new tank, it has to clear a federal efficiency minimum. That minimum is not one number. It is a formula based on the tank's rated volume, applied separately across four draw patterns, so a larger tank and a smaller one of the same type answer to different minimums. A licensed installer sizes the new unit to your household and confirms it clears the minimum that applies to that size.

- How do I know it's time to replace my water heater?
- Age is the first thing to check, along with how the tank is holding up. Rust-colored water, a tank that's damp or rusting on the outside, or water pooling underneath all point to the tank itself failing rather than a part that can be fixed. Popping or rumbling sounds during heating usually mean sediment has built up in the bottom of the tank, which makes the unit work harder and can shorten what's left of its life. If the water isn't getting as hot as it used to, or runs out faster than it did a year ago, a contractor can tell you whether that's a fixable problem or a sign the tank is done.
- Should I switch to a tankless water heater?
- It depends on what you're trying to fix. 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, and it doesn't sit there keeping a tank of water hot all day. If your current tank is failing and you're deciding what to replace it with, a tankless unit is worth asking a contractor about, since going tankless can mean changes to the gas line, venting, or electrical that a storage tank didn't need. If your water heater works fine, replacing it early for a tankless model isn't something to do just because it's newer technology.
- What changes when you install a tankless water heater?
- The biggest change is what feeds it. A tankless unit needs enough gas flow or electrical capacity to heat water on demand, which is more than a storage tank pulls at any one moment. The gas line or electrical circuit sometimes needs to be upsized to handle that. Venting is different too, since tankless units often use a different vent type than a standard tank. Mounting changes as well. Tankless units hang on a wall instead of sitting on the floor, which changes where it can go in the house. A contractor can look at what's already in place and say what needs to change for your home specifically.
