Fairmont homes run their water heater hard, eight months a year
Heat is on in Fairmont homes from October through May, and the water heater works right alongside it, warming water that starts out colder because the ground and the pipes feeding it are colder for most of the year. Winter nights averaging 24°F mean the incoming water is about as cold as it gets, and the tank has to make up that difference every time someone runs a shower or starts the dishwasher.
Power is part of the picture too. More than a third of West Virginia households lost power for a day or longer in 2024, and Marion County has seen 57 damaging wind events and 5 winter storms over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that relies on electric ignition will not light until the power is back. Whatever is installed, it has to meet the federal minimum efficiency for its size and type, which is set separately for each tank volume and draw pattern rather than as one flat number.

A heat pump water heater would save about $330 a year to run in West Virginia compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Water pooling around the base is the clearest sign, since it usually means the tank itself has started to leak from the inside out. Rusty or metallic-tasting hot water is another, especially if it happens right after the tank refills. If the unit is making rumbling or popping sounds, sediment has built up on the bottom and is starting to affect the heat exchanger. A water heater that runs out of hot water faster than it used to, or takes longer to reheat, is losing capacity and won't get better on its own. Once a tank starts showing two or more of these signs, a contractor can tell you whether it's worth repairing or time to plan a replacement.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and how your house is set up, not on one right answer for everyone. A tankless unit heats water on demand instead of storing it, so you don't run out during back to back showers, and it keeps running when you're not using much water instead of cycling a full tank. It needs proper gas line sizing or an adequate electrical circuit, and venting has to be done to the manufacturer's spec, which can mean more work than swapping in another tank. If your house loses power for stretches, worth knowing that an electric tankless unit stops working the moment the power does, while a gas storage tank with a standing pilot keeps heating water through an outage. A contractor can walk your house and tell you what changes tankless would actually require.
- What changes when you install a tankless water heater?
- The unit itself is much smaller and mounts on a wall instead of taking up floor space, so where it goes in the house usually changes. It needs venting sized and routed to the manufacturer's spec, which is often different from what a tank used. Gas units may need a larger gas line to deliver enough fuel for the burner to heat water on demand, and electric units may need a dedicated circuit sized for the load. Because it heats water as it flows rather than storing a tankful, there's no reservoir to run out, but flow rate and temperature rise both affect how much hot water it can deliver at once. A contractor can check your gas line, venting, and electrical setup before install to confirm what needs to change.
