Monitor Water Heater’s Performance:

You cannot expect an endless supply of hot water all the year round just installing a Rinnai Tankless Water Heater unit in your home. You need to take a good care of your water heater if you wish for a flawless supply. But, how would you know that your water heater unit requires maintenance? Confused, what to do now?

Drain The Boiler:

With the passage of time, the minerals as well as other elements in the water cause sediment build-up inside the tank. Thus, the efficiency of your water heater decreases with time and delay to pass hot water. In order to get rid of this, you need to drain the tank as soon as you notice the water heater unit requires maintenance. Even if you do not find much difference in the performance for the first few months or years after installation, don’t forget to check and drain the boiler tank at least once in every six to seven months.

Flush The Boiler Tank:

Flushing the tank is the best way to prevent sediment build-up and increase the efficiency and the lifespan of your water heater. Therefore, to keep your Rinnai water heater unit working perfectly, remember to flush the boiler tank at least once in a year. Always keep in mind that regular maintenance keeps the water heater efficient for an extended period and prevent corrosion. So, you are more likely to get hot water supply for years if you effort to take proper care and do required maintenance over time.

Use Vinegar While De-Scaling:

If your home is located in hard water region, and the water contains lots of mineral elements, use food-grade white vinegar while descaling the boiler. It can be an effective way to boost the performance as well. It also helps to reduce sediment build-up inside the boiler tank and prevent corrosion.

Call In a Professional:

Though you can take care of the things mentioned earlier by yourself going through the instructions provided with the unit, do not dare to repair or replace an equipment (if you ever need to) inside the unit. Remember, safety comes first! So, call in a professional if need be. Don’t invite dangers to visit your home just to save some bucks!
