Eight months of cold ground water to heat
Michigan City homes need heat from October through May, eight months a year. That same stretch, the water coming into the tank starts out cold, colder still on winter nights that average 20°F from December through February.
LaPorte County has recorded 60 damaging wind events over the past ten years, and across Indiana, 17% of households went at least 24 hours without power in 2024. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition does not, until the power is back. Whichever type goes in, it has to meet the federal minimum efficiency set for its tank size, a number that changes with the volume rather than one flat figure for every heater.

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?
- If your water heater is old enough that you're wondering, that's usually a sign to start planning for a replacement before it fails outright. Look for rust colored water, a tank that's damp or wet at the base, or water that won't get as hot as it used to. A popping or rumbling sound during heating means sediment has built up in the bottom of the tank, and that shortens what's left of its life. If a contractor tells you the tank itself is leaking rather than a fitting, that's not something to repair. Once a tank starts to go, it tends to go fast, and this area sees enough winter storms and wind events that you don't want to be choosing a water heater in the middle of an outage.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just the water heater itself. A tankless unit heats water on demand instead of storing it, so you don't run out partway through a shower with a full house, and it keeps working without holding a tank of hot water all day. The tradeoff is the install itself. Tankless units often need different venting and gas line sizing than a storage tank, so switching is more involved than a straight swap. If your current tank still has good years left, there's no rush. If you're replacing anyway, it's worth asking a contractor to look at your gas line, venting, and how much hot water your household actually uses at once, since that's what decides whether tankless makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is that there's no tank storing hot water, so the unit fires up only when you turn on a hot tap and heats the water as it passes through. That means the venting is different from a standard tank, often a different size or routed differently, and the gas line supplying it may need to be upsized since a tankless unit draws more gas while it's running. Some installs also call for an upgraded electrical connection for the unit's controls. None of this makes the swap impossible, but it's more than pulling one unit and setting in another, so a contractor will need to check your home's gas line, venting path, and electrical setup before pricing the job.
