Step-By-Step Maintenance Tips to Keep Your Tankless Water Heater in Peak Efficiency

If you have made the wise investment into a tankless water heater, then you will understandably want to take the steps necessary to keep it in top working order and to ensure that it is as efficient as possible. The best way to do that is to work with High Speed Plumbing to set up a maintenance program. However, you can also do some maintenance on your own. Keep reading to get a step-by-step guide on how to do so.

It’s Essential to Remove Lime Scale from Your Tankless Water Heater

The most important aspect of your ongoing maintenance program for your tankless water heater is to ensure that your heat exchange elements do not have lime scale buildup. If you see that you have just a light coating of scale buildup, you may assume that the issue is not serious – but in fact it could be having a huge impact on how efficient your system is. If you do not treat it, this building can result in longer burner cycles – which not only increases utility costs but adds strain to your system. Over time, this can shorten its natural lifespan.

Step-by-Step Instructions to Get You Started

The most important thing to do is to read the manufacturer’s cleaning instructions. If you do not have the owner’s manual, simply look it up online. If they do not give you specific directions on what cleaner to use, you can choose white vinegar for an eco-friendly option.

 

Before you begin cleaning, turn off the power source. Take off the lid from your water heater. This generally just requires removing a few screws. Find the three water valves that supply water to the heater and close them off. Then slowly remove the purge port valve caps on the cold and hot water valves. This gets rid of any pressure that has built in the valves and prevents hot water from shooting out and injuring you.

 

Then attach hosing lines to each of the three valves. These should have come with your tankless water heater. Then open the purge port valves by twisting them to the position of the cold or hot water valves. Use 2 ½ gallons of water vinegar to clean out the heater. Flush it and drain it, following the directions that your manufacturer sets out. Then close the purge ports by twisting the handles.

 

Disconnect the hosing lines form each water valve, put the purge port valve caps back, and make sure everything is tightened. Find the filter, take it off, clean out the housing and inside of the filter by running it under water, then replace it. Follow the instructions of your manufacturer to turn the water heater back on.
