Eight months of cold water demand in Plainfield
From October through May your water heater is working, not sitting idle. Winter nights averaging 22°F mean the incoming water is cold, and the tank has to make up that difference before it ever reaches your tap.
Plainfield has seen its share of winter storms and damaging wind, and in Indiana about 17% of households lost power for a full day or more in 2024 alone. A tank with a standing pilot will relight itself when the power comes back. One with electronic ignition needs that ignition system working right, since it won't restart on its own. Either way, a new installation should be sized and rated for the demand your household actually puts on it. The federal minimum efficiency for a storage water heater is set by a formula tied to the tank's rated volume, and it's applied differently across four draw patterns, so the right minimum for your home depends on the size and type of heater going in.

- How do I know it's time to replace my water heater?
- The clearest sign is age, since older tanks fail from the inside before they fail all at once. Rust-colored water, a tank that's noisy or rumbling, or water pooling underneath it all point to the tank itself failing, not just a part. If the unit is still fairly young and the problem is something like a heating element or thermostat, a repair usually makes more sense than replacing the whole thing. A contractor can look at the tank and tell you which situation you're in.
- 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. Tankless units heat water on demand instead of storing it, so you don't run out partway through a shower, and they take up much less wall space than a tank does. They also cost more upfront and often need changes to gas lines or venting to install. A contractor can look at your house and tell you what the switch would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is where the unit goes and what feeds it. Tankless units mount on a wall instead of standing on the floor, which frees up the space a tank used to take. Because they heat water instantly rather than storing it, they often need a larger gas line or a dedicated electrical circuit than what already runs to your old tank, plus venting rated for their higher heat output. A contractor can tell you whether your home needs those lines upgraded.
