AFUE must go?

ASHRAE wants $350 for article....

Hi Everyone,

Remember the article about boiler efficiency that started all of this? I asked ASHRAE if I could post it here on the wall. They said they want $350 to post on an internet site.

You can get the article yourself. Go to www.ashraejournal.com. Under "search for articles" type "Durkin" which is the authors name. Click on the article "Boiler system Efficiency". They want $8.00 to download the pdf. If you are an ASHRAE member it is free.

And the truth is:

What you say is not the mumbo-jumbo gobbly-gook that it appears on the surface. The older I get the more I despair over what's happened to marketing. How are we (the soldiers in the trenches, as it were) to look the customers in the eye and explain that the bait they are mouthing has hooks in it? Why would they believe the soldiers when they can see for themselves the slick-page claims promising comfort and giant savings all at once? And what happened to Truth In Advertising? And I am taking cooking classes. It either tastes good or it doesn't; and sometimes it is a matter of opinion.

AFUE is a huge problem...

Christian,

AFUE is very bad. It doesn't work at all. The testing methods are outdated. The science behind it has been proven wrong on a number of fronts. It doesn't reflect at all how the boiler or furnace works in your house. Some boilers with high AFUE are proving to be less efficient then boilers with lower AFUE. That is why I am making these statements here.

Condensing boilers are proving to be at least three times more efficient as conventional boilers. We need to fix AFUE and get something more accurate.
