Winters here are hard on a water heater
December through February nights in Baraboo average 13°F. Groundwater coming into the tank is cold, and the heater has to work harder to bring it up to temperature. With a heating season that runs October through May, that tank is rarely getting a break.
Power isn't guaranteed either. Wisconsin saw 18% of households lose power for 24 hours or more in 2024, and Sauk County has logged 12 winter storms and 61 damaging wind events over the past ten years. A new install should account for what happens to hot water when the power goes out, not just how it performs when it's on. Whatever size tank goes in, it has to meet the federal minimum efficiency set for that size, since the standard scales with tank volume rather than applying one number to every heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water that comes out lukewarm or runs cold faster than it used to. Rust colored water from the hot tap, rust around the tank itself, or a puddle forming at the base are all signs the tank is failing rather than just aging. A tank that's making rumbling or popping noises has sediment built up on the bottom, which makes it work harder and wears it out sooner. If your water heater is more than 10 to 12 years old and showing any of these signs, replacing it before it fails outright means you get to choose the timing instead of dealing with a flooded closet.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your house can support. A tankless unit heats water on demand instead of storing it, so you won't run out during a long shower or back to back loads of laundry, but it needs enough gas supply or electrical capacity to fire up at that rate, and that sometimes means upgrading a gas line or adding circuits. A storage tank is simpler to install and usually costs less upfront, but it has a limited supply and keeps water hot around the clock whether you're using it or not. A contractor can look at your gas line, venting, and electrical setup to tell you which one your house is actually ready for.
- What changes when you install a tankless water heater?
- The biggest change is venting. Tankless units burn hotter and more efficiently than a tank, so they need different venting material and often a different path through the wall or roof than what's already there. Gas fired tankless units also draw more gas at peak than a tank does, so the gas line sometimes needs to be resized to keep up. Because there's no tank storing water, the unit also needs a minimum flow rate to turn on, which is why a single low flow fixture like a bathroom faucet sometimes won't trigger it on its own. None of this makes tankless a bad choice, it just means the installation involves more than swapping one unit for another.
