Whether you’re considering an upgrade to a tankless water heater or are already enjoying the benefits of a tankless system, understanding how to care for it is crucial. Keeping your tankless unit in prime condition is key to ensuring you always have access to hot water when you need it.

Below, Hometown Plumbing explains the importance of flushing your tankless water heater and the steps involved.

Why a Tankless Water Heater Needs to be Flushed

If you’re the proud owner of a tankless water heater, you’re likely enjoying the reliability of on-demand hot water and more space in your utility room. But did you know that even this sleek system needs routine cleaning?

Over time, minerals from your water can build up inside the heater’s components, reducing efficiency and potentially increasing the costs of your energy bills. Flushing out these mineral deposits helps maintain the heater’s performance, ensuring you get instant hot water when you need it most while keeping your energy bills lower. 

Be sure to have your water heater flushed annually, and add this task to your yearly home maintenance to-do list.

Steps for Flushing a Tankless Water Heater

Flushing your tankless water heater might sound like a chore, but the process will be hassle-free with help from a pro. The plumbers at Hometown Plumbing will perform the following steps when flushing your tankless water heater:

  1. Turn off the system: We’ll turn off the power to your water heater. We’ll also turn off the gas valve if you have a gas-fueled system.
  2. Prepare the equipment: Our plumbers will grab a bucket, hoses, a submersible pump, and a non-toxic descaler.
  3. Connect everything: We’ll connect the hoses to the water valves (usually marked as hot and cold on your heater). Then, we’ll place the other ends in the bucket to catch the flushing solution.
  4. Circulate the solution: With the pump in the bucket, we’ll circulate the descaler through the system. This will break down and flush out any buildup.
  5. Flush and fill: After circulating the solution, we’ll disconnect everything and turn on the cold-water valve to flush the system thoroughly. Once clear, we’ll reconnect your heater to the power source or gas line.
  6. Reconnect everything: Your tankless water heater is officially flushed. Our team will put every part back in place, including plugging the service port caps and turning on the water and gas valves.

When It’s Time to Call the Professionals

Basic maintenance, such as keeping the area around the system clear, is easy. However, sometimes it’s best to call a professional to tune-up your system. If you’re unsure about the process, notice any leaks, or if your system hasn’t been maintained in a while, a professional plumber can ensure everything is done safely and effectively.

Remember, tackling more complex maintenance or repairs on your own can lead to bigger issues in the future. It’s always best to rely on skilled technicians for tankless water heater maintenance and repairs.
