A water heater here works eight months of winter and more
Water in Carmel comes into the tank cold, and December through February it comes in near freezing. Your water heater has to work harder to bring it up to temperature, and it does that work from October through May, eight months a year.
The county has seen 11 winter storms and 69 damaging wind events over the past ten years, and in Indiana about 17% of households lost power for a full day or more in 2024. A gas water heater with a standing pilot stays lit through an outage. One with electronic ignition will not fire until power is back. Either way, when you're picking a replacement, it's worth asking which one you're getting. Federal efficiency minimums for storage tank water heaters are set by size and draw pattern, so the right minimum depends on the tank you need, not a single number that applies to all of them.

- How do I know it's time to replace my water heater?
- Water pooling at the base of the tank means it's already failing and needs to be replaced, not repaired. Rusty hot water, a pilot light that won't stay lit, or a tank that's old for its type are other signs worth taking seriously. A popping or rumbling sound during heating means sediment has built up on the bottom of the tank, and once that starts the tank's years are numbered. Homes here need hot water every month, October through May and beyond, so a tank on its way out tends to fail at the worst time.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. A tankless unit heats water on demand instead of storing it, so you don't run out partway through back to back showers. It won't suit every home the same way, since gas line size and venting both matter for a tankless install, and a contractor needs to check both before you commit. If your current tank still works, there's no reason tied to its age alone to switch.
- What changes when you install a tankless water heater?
- The unit mounts on a wall instead of taking up floor space, and it needs its own venting run to the outside. Gas fired tankless units often need a larger gas line than a storage tank used, because they draw more fuel in the moment to heat water fast. Electrical and water connections get rerouted to the new location too. A contractor will look at your home's gas line, venting path, and electrical setup before pricing the change, since what's already there decides how much has to be added.
