Greetings, homeowners and DIY enthusiasts! Tankless water heaters are becoming increasingly popular due to their energy-saving benefits and convenience. However, just like traditional water heaters, they need regular maintenance to function at their best. In this article, we will guide you through the steps of cleaning your tankless water heater, as well as discuss its advantages and disadvantages. So, let’s get started!
Introduction
Before we dive into the cleaning process, let’s talk about tankless water heaters. These innovative appliances heat water on demand, providing hot water only when needed, unlike traditional water heaters that store hot water in a tank. Tankless water heaters are more energy-efficient and cost-effective in the long run since they don’t constantly heat and reheat water. However, like all appliances, tankless water heaters require maintenance to prevent damage and ensure optimal performance.
If your tankless water heater starts to malfunction or experiences a decrease in performance, it may be due to mineral buildup. Hard water contains minerals such as calcium and magnesium that can accumulate in the heater’s interior, reducing its efficiency and lifespan. Cleaning your tankless water heater regularly can prevent mineral buildup and keep it running smoothly.
Now, let’s get into the nitty-gritty of cleaning your tankless water heater.
How to Clean a Tankless Water Heater
Step 1: Turn off the Power and Water
The first step in cleaning your tankless water heater is to turn off the power and water supply. This will prevent any accidents or injuries from occurring. Locate the circuit breaker or power switch that controls your water heater and turn it off. Then, turn off the water supply valve that connects to the heater.
Step 2: Remove the Access Panel
Next, locate the access panel on your tankless water heater and remove it. This will give you access to the interior components, including the heat exchanger and valves. Be careful when removing the panel, as it may be attached with screws or other fasteners.
Step 3: Clean the Filter and Inlet Screen
Inside the access panel, you will find a filter and an inlet screen. These components prevent dirt, debris, and minerals from entering the water heater and causing damage. Remove the filter and inlet screen and clean them with a soft-bristled brush and water. Take note of any significant damage or wear and replace them if necessary.
Step 4: Flush the System
After cleaning the filter and inlet screen, it’s time to flush the system. Connect a garden hose to the hot and cold water valves and place the other end in a bucket or sink. Open the valves and let the water flow through the system for 20-30 minutes. This will flush out any mineral buildup or sediment that has accumulated in the system.
Step 5: Descale the Heat Exchanger
Once the system has been flushed, it’s time to descale the heat exchanger. Mineral buildup can reduce the heat exchanger’s efficiency, leading to decreased performance and higher energy bills. To descale the heat exchanger, you will need a descaling solution specifically designed for tankless water heaters. Follow the manufacturer’s instructions on how to use the solution properly.
Step 6: Reassemble and Test
After descaling the heat exchanger, it’s time to reassemble all the components and test the water heater. Replace the filter and inlet screen, and securely reattach the access panel. Turn on the water and power supply and let the water heater run for 10-15 minutes. Check for any leaks or malfunctions and make sure the water is flowing smoothly.
Step 7: Repeat the Process
To keep your tankless water heater in top condition, we recommend cleaning it every six months or as often as your manufacturer suggests. Regular cleaning will prevent mineral buildup and extend the life of your appliance.
