Signs Your Immersion Heater Needs to be Replaced

One way to lower equipment costs for businesses is to make sure that each piece of equipment functions to its full potential. When it comes to heating elements this can be quite a challenge. Such equipment does indeed have a limited life. However, when an immersion heater fails it is not always due to age. There are other factors that can lead to failure. 

Common Element Failures

Elements that are poorly maintained will eventually create poor heat transfer and inevitably fail after a period of time. However, before replacing, check the heater and the system to make sure it is not simply a buildup of sludge or sediment causing the issue. Sometimes the fix can be as easy as cleaning away debris from the element. Here, we outline some of the most common reasons why this happens and how to know when replacement is necessary.

Missing thermal protector: This could be caused by the protector being removed during installation or prior to servicing. WARNING: Do not operate heaters without thermal protection. 

No power/electrical fusing: This is often caused by the main disconnect being in an off position; open protector(s) or defective circuit breaker on main; loose or disconnected wiring. 

Thermostat not turning heater on (new installations): This will occur when the thermal protector is not connected to terminal blocks in control.

Heater blowing electrical protectors: The protector size must be consistent with the rating information stamped on heater nameplate/installation tag. 

Repair or Replace?

The main consideration businesses must make when deciding whether to repair or replace an immersion heater is the costs and benefits of repair vs. replacement. Depending on the situation you can either repair or replace the heater. If the damage is severe then replacement might be the better option. A second thing to consider is the value. It is not always viable to constantly repair an older unit even if it is possible. A newer immersion heater will simply give you greater value and last longer than your present unit which has probably seen better days. 

In the final analysis, no heating element lasts forever. However, when certain precautions are taken your immersion heater can have a life that is as long as any other vital equipment you own.
