Tankless water heaters are the space-saving superheroes of home hot water. But even these mighty minis need a little TLC now and then. Especially in areas with hard water, mineral buildup can creep in and reduce their efficiency. The good news? Flushing your AO Smith tankless water heater is a relatively simple process that can extend its lifespan and keep your hot water flowing freely.
Why Flush Your AO Smith Tankless Water Heater? It’s All About Performance
Think of your tankless water heater like a hardworking athlete. Mineral buildup, also known as scaling, acts like tiny weights, hindering its performance. Here’s how:
- Reduced Heat Transfer: Scale acts like an insulator, making it harder for the heater to transfer heat efficiently to the water.
- Decreased Water Flow: Buildup can narrow water passages, leading to a weaker flow at your faucets.
- Lifespan Matters: Regular flushing helps prevent malfunctions and keeps your tankless water heater running strong for years to come.
- Warranty Considerations: Some AO Smith warranties might require proof of periodic flushing, so be sure to check yours!
Preparing for the Flush: Gear Up for a Smooth Process
Before we unleash the descaling solution, let’s gather the essentials for a successful flush:
Flushing Essentials:
| Descaling Solution: Choose a product specifically formulated for tankless water heaters. Always follow the manufacturer’s instructions for dilution! |
| Circulation Pump: A small pump helps efficiently circulate the descaling solution through the system. |
| Buckets: To hold the descaling solution and collect wastewater. |
| Hoses: The right size and length to connect the pump to your water heater’s designated flushing points. |
| Safety Gear: Eye protection (goggles) and gloves are recommended, depending on the descaling solution. |
AO Smith Tankless Water Heater Flushing Kits: Convenience vs. Cost
