If you’re reading this, it’s likely you’re wondering how to flush a tankless water heater. Regular maintenance of your water heater is crucial for its longevity and efficiency, and flushing is a key part of that routine. But what’s the best way to flush a water heater? Let’s dive into it.
What Is a Tankless Water Heater?
A tankless water heater, also known as an on-demand or instant water heater, provides hot water only when needed, unlike traditional storage water heaters that heat and store water in a tank. This makes them more energy-efficient and reduces the risk of running out of hot water. However, they can accumulate minerals from hard water over time that need to be flushed out.
Why Flushing Is Crucial
Flushing your tankless water heater helps remove any sediment buildup from the bottom of the tank. This buildup can impact the heater’s performance, reduce its lifespan, and lead to higher energy bills. So, knowing how to flush a tankless water heater and doing it on a regular basis is essential.
How to Flush a Tankless Water Heater
Here is a step-by-step guide on how to flush your tankless water heater.
Step 1: Turn Off the Power
Safety first! Before you begin the flushing process, make sure you have turned off the water heater. If you have an electric water heater, turn off the power at the breaker box. For a gas water heater, you’ll need to shut off the gas.
Step 2: Connect the Hoses
Next, connect two water hoses to the hot and cold water service valves. The other end of the hose should be connected to a sump pump in a bucket. Another garden hose should be connected from the pump to a drain or outside.
Step 3: Open the Drain Valve
Now, it’s time to open the drain valve. This will allow the water to flow out of the tankless water heater and through the hoses.
Step 4: Flush With Vinegar
Many homeowners will say that the best way to flush a water heater that is tankless is to use white vinegar. Fill the bucket with two and a half gallons of white vinegar. Turn on the pump and let the vinegar circulate through the water heater for about 45 minutes. Vinegar is a safe and natural way to dissolve the mineral deposits.
Step 5: Rinse and Restart
After flushing, disconnect the hoses and reconnect the cold water supply. Turn on the cold water valve to rinse the unit for a few minutes. Then, restore power or gas to your water heater, and it’s back to business!
