Eight months of heating, and a grid that doesn't always hold
Moundsville needs hot water for showers and heat for the house from October through May. Winter nights average 24°F, so whatever you install has to perform through a long, cold stretch, not just a mild snap here and there.
Marshall County has had 8 winter storms and 36 damaging wind events over the past ten years, and across West Virginia over a third of households lost power for at least a day in 2024. A storage tank holds its heat and recovers on its own once power is back. A tankless unit depends on electricity to fire, so an outage means no hot water until the power returns. Either way, the new unit has to meet a federal minimum efficiency rating, and that minimum is set by your tank's size, so the right number depends on the water heater you're replacing.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tank water heaters last a decade or so, and once you're past that, a repair might buy a little time but not much. Rusty water, a tank rusting on the outside, or water pooling underneath means the tank itself is failing, and that can't be fixed. If it's newer and just not heating well, a contractor can check the heating element or thermostat before you replace anything.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your house being unusual in any way. A tankless unit heats water only when you run a tap, so you don't run out during a long shower, and it takes up much less space than a tank. It costs more upfront than a tank heater, and a contractor needs to check whether your gas line or electrical circuit can support it before you switch. If your current tank is working fine and just aging, that's worth weighing against starting fresh with tankless.
- 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. There's no tank to run out, so hot water keeps coming as long as the tap is open. The unit itself is smaller and usually goes on a wall, which frees up floor space a tank would have used. Venting is different too, since a tankless unit needs its own vent sized for it, which is part of what a contractor sets up during installation.
