In order for condensing boilers to realize their potential for increased efficiency, they’ve got to be allowed to condense. You do that by lowering the hot water supply temperature set point which, in turn, lowers the return temperature as well. Many boiler manufacturers offer more than one pre-set curve while others allow manipulation of the set points themselves. In either case, with a little planning and some understanding of how the boiler controls actually work, you can increase the seasonal efficiency of your boiler with little or no added first cost. - See more at: http://buildingenergy.cx-associates.com/2012/04/getting-the-most-out-of-your-condensing-boiler/#sthash.Q0Vqyq9F.dpuf

For condensing boilers to realize their potential for increased efficiency, they’ve got to be allowed to condense. You do that by lowering the hot water supply temperature set point which, in turn, lowers the return temperature as well. With a clear understanding of how condensing boiler controls actually work, and careful planning, you can significantly increase the seasonal efficiency of your condensing boiler with little or no added first cost.
