With our next Today’s Boiler scheduled for May, I don’t want to wait that long to keep you apprised on the latest in the ongoing saga of finalizing and implementing new boiler regulations. Even last month’s ABMA meeting is not the latest, but ABMA president Randy Rawson has sent his members (including ES) a good summary of the present situation. So with thanks to him, I am providing an excerpt of his update below. If you have trouble keeping up, don’t feel bad.
The company has released two condensing gas boilers, Models 550 and 750. Features include 93.9% thermal efficiency, 94% combustion efficiency, low NOx certification, PVC venting for direct vent and direct exhaust, and 20% to 100% modulation.
