Delaware County asks a lot of a water heater
Winter nights here average 23°F, and homes run their heat from October through May, eight months of the year. That is eight months where the water coming into the tank is colder than it is the rest of the year, so the heater works harder to bring it up to temperature.
The power goes out here too. Across Ohio, 18% of households lost power for 24 hours or more in 2024, and Delaware County has logged 94 damaging wind events and 5 winter storms over the past ten years. A new installation is worth planning around that, since a storage tank holds hot water through an outage in a way that other setups do not.

- How do I know it's time to replace my water heater?
- Age is the biggest clue, so check the tag on the tank for its install date. Once a tank water heater gets old, a repair often just delays the next breakdown instead of fixing the real problem. Watch for water that takes longer to heat, rust-colored water from the hot tap, or rumbling and popping from the tank, which means sediment has built up on the bottom. A leak at the tank itself, rather than at a fitting or valve, means the tank has failed and needs replacing, not repairing.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. A tankless unit heats water on demand instead of storing it, so you get a steady supply of hot water as long as you're running it, without waiting for a tank to refill and reheat. It won't run out the way a tank can when several people shower back to back. Whether it's worth switching comes down to your home's gas line, venting, and hot water use, which is something a contractor needs to look at in person.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space. Because it heats water on demand rather than storing it, it needs a large enough gas supply line and its own dedicated venting, which the old tank setup may not have had. Installing one often means running new gas piping and vent work rather than swapping one unit for another in the same spot. A contractor can tell you what your home's existing lines and venting can support before you decide.
