What a Lancaster winter asks of a water heater
Winter nights in Fairfield County average 24°F, and homes here run their heat from October through May, eight months of the year. A water heater doesn't get much of a break in a stretch like that.
Power is part of the picture too. Across Ohio, 18% of households lost power for 24 hours or more in 2024, and Fairfield County has logged 13 winter storms and 81 damaging wind events over the past ten years. A storage tank with a standing pilot keeps making hot water through an outage. One that depends on an electronic igniter does not, until the power comes back. Sizing matters as well. The federal minimum efficiency for a storage water heater is set by its tank volume, checked differently depending on how a household draws hot water through the day. Two heaters of the same type and different size can face different minimums, so the right one for your home comes down to its size and type, not a single number on a label.

- How do I know it's time to replace my water heater?
- The clearest sign is water around the base of the tank, since that usually means the tank itself is failing from the inside and won't stop once it starts. Rusty or metallic-tasting hot water is another sign, along with rumbling or popping noises from sediment built up on the bottom. If your water heater is a storage tank model past 10 years old and needs a repair, replacing it is usually the better call, since the tank is closer to the end of its life than the start. A cold night here means you'll notice a failing water heater fast, so it's worth acting on these signs before you're left without hot water.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether tankless is better in general. A tankless unit heats water only when you call for it, so you won'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. Tankless units also last longer than most storage tanks. What it won't do is deliver hot water instantly at the tap, since the water still has to travel through your pipes. A contractor can look at your home's gas line, venting and water demand and tell you whether tankless makes sense for your house specifically.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand, which means the unit itself is small enough to mount on a wall instead of taking up floor space. Because it heats water as it flows through rather than keeping a tank full and hot around the clock, a tankless unit often needs a larger gas line and its own venting than a tank did, since gas fired models pull more fuel in short bursts. The install usually means new venting run to the outside wall, and sometimes an upgraded gas line to supply it. A contractor will check your home's existing gas line and venting to see what needs to change before swapping in a tankless unit.
