What Clifton winters ask of a water heater
Clifton needs heat from October through April, seven months of the year, with winter nights averaging 29°F from December through February. A water heater here is working through most of the calendar, not just a few cold weeks.
Power isn't always steady. Across Arizona, 7% of households lost power for at least 24 hours in 2024, and Greenlee County has seen 26 winter storms and 15 damaging wind events over the past ten years. A new installation should account for what happens when the power drops on a cold night. Any storage water heater installed today also has to meet the federal minimum efficiency for its size and draw pattern, which is set by formula rather than one fixed number, so the right minimum depends on the tank you choose.

- How do I know it's time to replace my water heater?
- Age and how it is failing tell you most of what you need to know. Once a storage tank starts leaking from the tank itself, that is the tank rusting through from the inside, and it will not stop. Rusty hot water, a puddle at the base, or hot water that runs out fast when it used to last are all signs the tank is on its way out. If the water heater is not that old and is just not heating well, it might only need a new thermostat or heating element, so it is worth having a contractor look before you replace it.
- 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 do not run out of hot water partway through a shower, and it takes up much less space than a tank. It usually means changes to the gas line, the vent, and sometimes the electrical, so a contractor needs to look at your setup before you know if it makes sense for your house.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of standing on the floor, but what changes around it matters more. Tankless units often need a larger gas line to keep up with the burner, a different vent than a tank uses, and sometimes a dedicated electrical circuit. Those changes depend on the house, so a contractor needs to see the existing setup to say what is involved for yours.
