Modulating Condensing Fuel-Fired Boilers

COURSE NO: M02-008
Modulating Condensing Fuel-Fired Boilers
Course Highlights

This online engineering PDH course describes the benefits of using modular condensing boilers and water heaters along with the installation and maintenance considerations. In addition, the course explains about certifications, emissions, life-cycle costs and case studies using this technology.


A modulating/condensing fuel fired water heater or hydronic boiler can avoid losses associated, in conventional units, with cycling at less than full load and with un-recovered latent heat of water produced in the combustion process.  A system which incorporates features that minimize cycling by modulating fuel and air flow to the combustor and that recover additional heat from condensing moisture in the flue gas stream can achieve reductions in fuel consumption, operating costs, and emissions.


This 2 PDH online course is applicable to mechanical engineers who work with systems involving fuel fired water heaters and boilers.

Course Quiz
Once you complete your course review, you need to take a multiple-choice quiz consisting of ten (10) questions to earn 2 PDH credits. The quiz will be based on this DOE/EE publication.
The minimum passing score is 70%. There is no time limit on the quiz, and you can take it multiple times until you pass at no additional cost.
Certificate of Completion

Upon successful completion of the quiz, print your Certificate of Completion instantly. (Note: if you are paying by check or money order, you will be able to print it after we receive your payment.) For your convenience, we will also email it to you. Please note that you can log in to your account at any time to access and print your Certificate of Completion.
