Modulating Condensing Fuel-Fired Water Heaters
and Hydronic Boilers
Steven G. Liescheidt, P.E., CSI-CCS, CCPR.
Overview
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 unrecovered 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.
In this course the student will learn about the
benefits of using modulating condensing boilers and water heaters along with the
installation and maintenance considerations. In addition, the student will
learn about certifications, emissions, life-cycle costs and case studies using
this technology.
The student is expected to read and review the material contained
in Modulating/Condensing Fuel-Fired Water Heater and Hydronic Boiler,
DOE/EE-0171.
The
student must take a multiple-choice quiz consisting of ten (10) questions at the end of
this course to obtain PDH credits.
