Pasco water heaters work most of the year
Winter nights here average 28°F from December through February, and homes need heat from October through May. That's eight months where the water coming into the house is cold and a water heater has to work harder to bring it up to temperature.
Power outages happen here too. Nearly a quarter of Washington households went at least a day without power in 2024, and the county has seen 14 winter storms and 25 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps running through an outage. One with electronic ignition won't light until the power is back.
Federal rules set a minimum efficiency for new storage water heaters, but the number isn't the same for every unit. It's a formula based on the tank's rated volume, applied differently depending on how the heater is used, so two tanks of different sizes can face different minimums even though they're the same type.

A heat pump water heater would save about $280 a year to run in Washington compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water around the base of the tank. Once a tank starts leaking, it will not seal itself back up, and it means the tank has rusted through from the inside. Water that comes out rusty or smells off is another sign, and so is a tank that cannot keep up with hot water anymore. If yours is showing any of these problems, replacement makes more sense than another repair.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support. A tankless unit heats water only as you use it, so you do not run out partway through a shower, but the flow rate matters more since it can only heat so much water at once. Switching usually means changes to the gas line, the venting, or the electrical circuit, since tankless units have different requirements than a tank. 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 venting changes first. Tankless units vent differently than tank models, often through a smaller pipe designed for their exhaust, so the existing vent usually cannot be reused as is. The gas line may need to be resized too, since tankless units can call for more gas flow at once than a tank does. Some installations also need a dedicated electrical circuit for the unit's controls. All of this is worth asking a contractor to walk through before deciding, since it affects the installation itself and not just the unit hanging on the wall.
