Danville asks a lot of a water heater
Winter nights here average 21°F from December through February, and homes need heat eight months a year, October through May. A water heater in an unheated basement or garage works against that cold every day it sits there, not just on the coldest nights.
Power doesn't always stay on to help it. Illinois saw 16% of households lose power for 24 hours or more in 2024, and Vermilion County has logged 7 winter storms and 163 damaging wind events over the past ten years. Most water heaters come back on by themselves once power returns, and a standing pilot model doesn't need power at all. Either way, the new one should be sized and installed to match the volume you draw, since the federal efficiency minimum for storage water heaters is set by tank size and use pattern, not one number for every unit.

- How do I know it's time to replace my water heater?
- The clearest sign is water that isn't hot anymore, or runs out fast. Rust colored water, a tank that's rusting on the outside, or a puddle forming underneath all point to a tank that's failing rather than something you can repair. Most storage water heaters last a limited number of years, and once one starts leaking from the tank itself, that's the end, not something a contractor can patch. If yours is old and starting to act up, it's worth having a contractor look at it before you're without hot water on a cold night.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is failing. A tankless unit heats water as it flows through rather than storing it, so you don't run out partway through a shower, no matter how many showers happen back to back. It's not automatically the right call for every house, since gas line size, venting, and where the unit will go all matter and a contractor needs to check them first. If your tank still works fine, this is a choice, not something you need to rush into.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, so where it sits in the house usually changes. It needs its own venting, and if it runs on gas, the gas line supplying it may need to be a larger size than what fed the old tank, since it draws more at once when it's heating water. There's also no standing reserve of hot water waiting in a tank, so it heats on demand every time a tap opens. A contractor will look at your gas line, venting, and electrical before installing one to confirm the house can support it.
