What a Vigo County winter asks of a water heater
Your water heater works into cold groundwater from October through April, seven months of the year. On nights that average 23°F, the tank has to make up more ground before the water at the tap feels hot. That is true every year here, not just in a bad stretch.
Power is part of the picture too. Across Indiana, 17% of households lost power for at least 24 hours in 2024, and Vigo County has recorded 49 damaging wind events and 5 winter storms 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, gas or electric, will not come back on until the power does, though most will resume on their own once it is restored. New storage water heaters also have to meet a federal minimum efficiency, and that minimum is not one number. It is set by a formula tied to the tank's size and to how the home draws hot water, so two tanks of different sizes are held to different standards even if they are the same type.

A heat pump water heater would save about $350 a year to run in Indiana compared with an electric water heater.

- How do I know it's time to replace my water heater?
- If it's old and struggling to keep up, replacing it beats repairing it. Watch for water that never quite gets hot, rust-colored water, or rumbling and popping from the tank as sediment builds up on the bottom. Water pooling around the base is another sign, since that usually means the tank itself is failing and no repair fixes that. A furnace can limp along with a patched part, but a leaking tank only gets worse.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is old. Tankless units heat water on demand, so you don't run out partway through a shower with a full house, and they take up a fraction of the space a tank does. They also need more from your gas line or electrical panel to deliver that heat fast enough, which is a bigger part of the switch than the unit itself. A contractor can look at what's already feeding your current water heater and tell you what changes for your house.
- What changes when you install a tankless water heater?
- The biggest change is what feeds it. A tankless unit needs a larger gas line or a dedicated electrical circuit to heat water fast enough the moment you turn on a tap, so that line or circuit often needs upgrading during install. Venting changes too, since tankless units vent differently than a tank ever did. You also get an endless supply of hot water instead of a tank that runs out, but the space it frees up and the venting work involved are what a contractor has to plan around first.
