Kanawha County asks a lot of a water heater
Winter nights here average 27°F from December through February, and homes need heat seven months a year, October through April. A water heater is running through most of that stretch, not just a few cold weeks.
Power is not something to count on either. Across West Virginia, 35% of households lost power for at least 24 hours in 2024, and the county has logged 16 winter storms and 259 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One that depends on power for ignition does not.
Whatever you install has to meet the federal minimum efficiency for its size. That minimum is not one number. It is set by a formula tied to the tank's rated volume, applied differently across draw patterns, so a larger tank and a smaller one face different minimums even if they are the same type of heater.

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?
- Watch for water pooling at the base or rust in the water itself. Either one means the tank is failing from the inside, and that does not get better. If the heater is struggling to keep up, taking much longer to heat a tank, or making popping and rumbling noises, sediment has likely built up on the bottom and the tank is working harder than it should. Age matters too. Most storage water heaters last a limited number of years, and once you are past that point, a repair on an old tank often just delays a bigger problem.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit only heats water as you use it, so you are not paying to keep a tank of water hot all day, and you will not run out of hot water partway through a long shower. But switching usually means changes to the gas line, venting, or electrical circuit feeding the unit, since tankless heaters draw more power in the moment than a tank does. A contractor can look at your home and tell you what that switch would actually involve.
- What changes when you install a tankless water heater?
- The unit itself is much smaller than a tank, so it usually goes on a wall instead of taking up floor space in a closet or utility room. Because it heats water on demand rather than storing it, the gas line or electrical circuit supplying it often needs to be sized up to handle that peak demand. Venting changes too, since a tankless heater vents differently than a tank does. None of this is a straight swap, so a contractor needs to check what your home already has before installation.
