Quality HEATING ELEMENTS Essential for Duct Heater Reliability

Electrical duct heaters are among the most commonly used duct heaters in homes. These are very easy to install and are also low in maintenance. Duct heaters are ideal for various applications that include primary heating, secondary heating, reheating, etc. High-quality electrical duct heater's reliability depends upon several factors.

The essential parts of electrical duct heaters are transformers, contractors, etc which should be easily replaceable. However, in the electric duct heater, elements are critical components and can be difficult to replace. Listed below are few factors that the lifespan of the electrical duct heaters depends upon.

 

Heaters Element

 

Nickel alloy is used to make an open coil in electric duct heaters for a heating element which emits energy through the outer surface. These duct heater's skin can heat up easily and reach up to 1700 degrees Fahrenheit. Due to the rise in temperature, the elements begin to oxides and degrade.

Therefore to ensure the longevity of the electrical duct heaters make sure that the surface temperature of the equipment element is at the lower level while also gaining the watt needed for your application.

 

WATT Density

WATT density refers to the watt per sq. In. of the element surface. Usage of longer gauge wire to enlarge the surface area will enable you to lower the watt density. This will cool the temperature on the element surface making sure that it will last longer.

 

Temperature Rating

If the heating element is of high quality they will be designed to function below their highest-rated temperature. There will be no red glow in the heating element when operating at the fullest capacity.

However, if there is a red glow in the heating element it could be the result of low quality or inadequate airflow and therefore will operate adjacent to its maximum temperate rate. This is an indication that the heating element is degrading and needs to be quickly replaced.

 

How To Ensure Reliability In Electrical Duct Heaters To Increase Its Lifespan?

Good quality and well designed electrical duct heater can easily last for more than 20 years. Therefore make sure to enquire and ask the design engineer for a lower watt density heating element during the construction of the heater. Ensure that the engineer uses correct CFM for heaters application along with the usage of high-quality parts in your duct heater. Another important factor to weigh in is the placement of the heater should be such that it provides necessary airflow. Apart from the above-mentioned tips to increase the lifespan of your electrical duct heater make sure that you keep your air filters spotless.
