A good boiler may last between 30 and 50 years, provided it is properly maintained and has quality controls. Autoflame and our global Tech Centre Network have worked on tens of thousands of commercial and industrial boilers over the past 40 years. Based on our experience, we’ve assembled data to help engineers, purchasers and managers better understand what options are available to them in our industry. Also, keep in mind that many boiler problems can be resolved by just replacing the burner and control.

Selecting the Correct Burner

Although most boiler manufacturers have partnerships with one or two burner manufacturers, in most instances you can choose whichever burner you would like. It is often to your advantage to specify your own burner, because the boiler manufacturer will often default to the cheapest, least energy efficient burner it has access to in order to keep their costs down. While this may reduce your purchasing price, it will cost you quite a bit more in the long run in fuel usage, excess emissions, service and parts. Click here to compare burners. 


Boiler Controls: The Most Important Step

The boiler and burner are the most expensive parts of a boiler system, but the last major component, boiler control, is perhaps the most critical. This is because how a boiler is commissioned and then managed will likely have more impact on fuel usage, emissions, servicing and total cost of ownership than any other factor.  Because boiler controls aren’t as expensive as the other parts, they are often mistakenly overlooked by the buyer. Boiler and burner companies view them as a necessary expense that they have to include in a quote, so they often tend to minimize their importance and go with the cheapest, least efficient, less reliable option. Save money and headaches by learning more about the difference quality controls can make. Click here to learn more about controls.
