Winters here put a real load on a water heater
Bartholomew County sees winter nights averaging 24°F from December through February, and homes here run their heat from October through April, seven months of the year. That's seven months where the water coming into the tank starts out cold, and the heater works harder to bring it up to temperature.
Power doesn't always stay on to do that work. The county has logged 10 winter storms and 40 damaging wind events over the past ten years, and across Indiana 17% of households lost power for 24 hours or more in 2024. A new installation should account for that, along with the federal efficiency minimum, which for storage water heaters is set by a formula based on tank size rather than one number for every unit.

A heat pump water heater would save about $330 a year to run in Indiana compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Age is the first sign. Once a tank water heater gets old, a failure can happen without warning, so it's worth knowing roughly how old yours is. Look for rust colored water from the hot tap, a tank that's damp or rusted around the base, or water pooling underneath it. Popping or rumbling sounds mean sediment has built up on the bottom of the tank, and that shortens what's left of its life. If your water heater is showing any of these signs, have a contractor look at it before it fails and leaves you without hot water or with a wet floor.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on your old tank failing. A tankless unit heats water on demand instead of holding a tankful hot around the clock, so it doesn't run out of hot water the way a tank can during heavy use. It also takes different venting and gas or electric supply than a tank does, so switching is more than a swap. A contractor can look at your home and tell you what changing over would actually involve.
- What changes when you install a tankless water heater?
- The unit itself is much smaller than a tank, since it's not storing any water, so it usually mounts to a wall instead of sitting on the floor. It needs venting sized and routed for its own exhaust, and often a gas line or electrical circuit sized differently than what fed the old tank. Because it heats water as it flows through rather than storing it, it also needs enough gas or electrical capacity to do that on demand. A contractor can check what your home already has and what would need to change to make the switch.
