Clark County asks a lot of a water heater
Winter nights here average 23°F, and the water going into the tank starts out cold. Homes run their heat from October through May, eight months of the year, and the water heater is working the whole time to make up that difference.
Power matters too. In Ohio, 18% of households went at least 24 hours without power in 2024, and Clark County has logged 7 winter storms and 88 damaging wind events over the past ten years. A new water heater should come back on by itself once power is back, without anyone having to relight it. Sizing matters as well. The federal efficiency minimum for storage water heaters is not one number. It is a formula based on the tank's rated volume, so the right minimum depends on the size of the tank going in, not just the type of water heater.

A heat pump water heater would save about $350 a year to run in Ohio compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Age is the first thing to check on your water heater, since most tank units are working on borrowed time once they get old. Look for rust colored water, a tank that sweats or drips down the side, or a pilot and burner that will not stay lit right. If the tank itself is leaking rather than a fitting or valve, that heater is done, since a leaking tank cannot be patched. Popping or rumbling noises during heating mean sediment has built up on the bottom, and while that alone does not mean replacement, it does mean the heater is working harder than it should.
- 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 heats water only as you use it instead of keeping a full tank hot around the clock, and it can keep up with steady demand as long as it is sized right. It needs a gas line sized for it or a dedicated electrical circuit, and venting suited to that specific unit, which is not always what a storage tank left behind. A contractor can look at your gas line, electrical panel and venting and tell you what switching would actually take in your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water comes on demand instead of out of storage, so there is no tank sitting full and heated all day. That means new venting sized for the unit, since tankless heaters vent differently than a storage tank does. Gas fired models often need a larger gas line than the old tank used, and electric models need a circuit sized for the unit's draw. The unit itself mounts on a wall rather than standing on the floor, which frees up the space the old tank used to take.
