Hi Top 10 HVAC! How to Clean Your Heat Exchangers!

We’re continuing our series this week on cleaning HEAT EXCHANGERS. This second post discusses cleaning HEAT EXCHANGERS, including the tools/products you need to get the job done.

"Here’s more about this week’s topic – cleaning heat exchangers":

Clean heat exchangers equate to tremendous energy savings, according to the U. S. Department of Energy. 

Scale deposits from magnesium, calcium and silica (from the water supply) form a layer on heat exchangers. 

Layers of deposits insulate the exchangers and slow down heat transfer, causing the exchangers to overheat or fail, reducing energy efficiency and causing more wear and tear on the system.

The Northwest Food Processors Association identifies soot as another cause of deposit build-up. 

Fuel oil combustion deposits as well as coal or wood waste can melt onto heat transfer surfaces. 

Once these deposits have melted, they can form a glass-like insulating layer that’s difficult to remove.

The association recommends reducing fuel costs by regularly cleaning heat exchangers to prevent fouling, which is often caused by a dirty, malfunctioning burner. 

Inspect heat exchangers at least once per year and clean them when they look dirty.

Inefficient heat exchange is caused by scale and sediment build up. 

A quality heat exchanger tube cleaner can quickly eliminate the problem. 

The step-by-step “How to Clean Heat Exchangers” check list walks you through the cleaning process. 

Choose HEAT EXCHANGER cleaning tools based on the type of system you have. 

Rotary tube cleaners work best on large HEAT EXCHANGERS. 

Tube cleaning drills clear small diameter tubes.

Use a biodegradable liquid de-scaler to loosen and remove tough DEPOSITS, while keeping the environment safe.

 A portable video scope that’s built for industrial use identifies DEPOSITS, for a thorough inspection.

Using a de scaler system circulates the de scaling fluid through the unit automatically. 

The scale is gone when the pH of the solution rises or the fluid stops foaming.
