What a Kankakee County winter asks of a water heater
Water heater installation in Kankakee County has to plan for eight months of heating season, October through May, with winter nights averaging 20°F. Cold groundwater coming into the tank means the heater works harder to bring it up to temperature, for most of the year.
Power is part of the picture too. Illinois saw 16% of households lose power for 24 hours or more in 2024, and the county has logged 9 winter storms and 99 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep running through an outage. One with electronic ignition will not light until power is back. Whichever type goes in, it has to meet the federal minimum efficiency for its size, since the rule is set separately for each tank volume and draw pattern rather than as one number for every heater.

A heat pump water heater would save about $360 a year to run in Illinois compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tanks are built to last about a decade, and past that point a failure gets more likely every winter you keep it. Rust-colored water, a tank that's rusting on the outside, or water pooling underneath are signs the tank itself is failing, not something you can fix with a part. If it's still working but struggling, like taking longer to heat or running out faster than it used to, that's the heating element or sediment buildup catching up with it. With winter nights here averaging 20°F, a water heater on its way out tends to show its worst side in the cold months, so it's worth replacing before it fails rather than after.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank still works. A tankless unit heats water on demand, so you don't run out during a long shower or back-to-back loads of laundry, and it takes up a lot less space than a tank. A contractor will need to check whether your gas line or electrical service can support it before you commit, since that changes what the install involves. Worth knowing too that a tankless unit needs power to run, same as a tank with an electric ignition, so neither keeps you in hot water when the power's out, and homes in Illinois saw outages of a day or more often enough in 2024 that it's worth planning for.
- What changes when you install a tankless water heater?
- The biggest change is that hot water shows up on demand instead of waiting in a tank for you to use it. That means no more running out partway through a shower, but the unit also has to work harder in the moment to bring water up to temperature, which is why gas line size and venting often get checked or upgraded during install. The unit itself mounts on a wall instead of taking up floor space, so where it goes in your house usually changes too. If you're on electric ignition rather than a standing pilot, it still needs power to fire up, so an outage takes out your hot water same as it would with a tank.
