Introduction

Just like how we need our coffee to be descaled for optimum performance, our tankless water heater needs it too! 

Descaling is necessary to remove the mineral build-up that can clog the system and affect its efficiency over time. So, if you want your water heater to last long and give you hot water whenever you want, descaling is the way to go. 

In the next sections, let’s talk about the signs, materials, and steps to descale your tankless water heater.

Signs That Your Tankless Water Heater Needs Descaling

If you’re experiencing any of these three things, it’s probably time to descale your tankless water heater. Does your shower turn from hot to lukewarm without warning? 

Is there knocking in the walls that sounds like a woodpecker? Are you stuck taking chilly showers every day? If you’re nodding yes, your unit is likely suffering from a build-up of minerals that are causing blockages in the system. 

Don’t wait until your water heater goes completely haywire. It’s better to descale it now and save yourself the hassle later.

Materials Needed for Descaling

When it comes to descaling your tankless water heater, you’ll need a few materials to get started. First up is a bucket to catch the water and vinegar solution. Then, you’ll need white vinegar, which is a natural and affordable descaling solution. 

A submersible pump kit will help you circulate the solution through your water heater, and a garden hose will be handy for draining the solution after descaling is complete. Remember, purchasing the right materials will make descaling a breeze, and you’ll have hot water in no time.
