What Marion asks of a water heater
Winter nights here average 27°F from December through February, and cold water coming into the tank means it has to work harder to bring it up to temperature. That happens through 7 months of heating season, October through April.
Power doesn't always stay on. Across Illinois, 16% of households lost power for 24 hours or more in 2024, and the county has logged 88 damaging wind events and 14 winter storms over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on an electronic igniter won't, until the power is back. Whatever goes in has to meet the federal minimum efficiency set for its size, and that minimum is different for every tank volume, so the number that applies to yours depends on how many gallons it holds.

A heat pump water heater would save about $250 a year to run in Illinois compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age, since most tanks wear out from the inside over years of use and a leak can start any day without warning once they're old. Water pooling at the base, rust-colored water, or a tank that's gotten noisy as it heats are all signs the inside is breaking down. If you're calling a plumber for the same problem more than once a year, replacing it is usually the better move over repairing it again.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says you should. A tankless unit gives you hot water on demand instead of storing a tankful, so you don't run out partway through a shower with a full house. It also takes up far less space than a tank. Against that, installing one usually means changes to the gas line, venting, or electrical supply, so the upfront work is more involved than a straight tank swap. A contractor can look at your home and tell you what that install would actually require.
- What changes when you install a tankless water heater?
- The unit itself is much smaller, so it usually goes on a wall instead of taking up floor space. Because it heats water as it flows through rather than storing it, it often needs a larger gas line or a dedicated electrical circuit to supply enough power for that instant heating. Venting is different too, since tankless units typically vent through a wall rather than up through the roof like a tank. Any of these can mean extra work beyond just swapping out the unit, so it's worth having a contractor walk through your specific setup before you decide.
