Tankless Hot Water Heaters

Descaling and Flushing Tankless Water Heaters

On-demand water heaters, or Tankless, can deliver great benefits to the homeowner.  The flexibility, increased efficiency, and compact size are just a few reasons they have become so popular.  However, with new things comes new maintenance to maintain high performance of your Tankless Heater.

One of the ongoing and one of the most important maintenance items is to make sure the Heat Exchanger Elements are free from lime scale or scale as is commonly called.  The buildup is well known throughout the industry.  This is similar to the scale build up in your coffee pot.  Just a light coating of scale buildup can have serious impact on the efficiency of the system, causing water heaters, boilers and more to run longer burner cycles.  This leads to strain on the heat exchanger and a shorter lifespan.

How often is this maintenance recommended or required?  The limescale buildup will differ depending on the quality of the water being used, location, and amount of use, to name a few.  A good rule of thumb is once a year.
