(This is the opposite of the technique employed for non-condensing boilers, where the efficiency will decrease as the load reduces.) However, the use of a single boiler will increase the risk of total system failure (as there is no redundancy), limit the opportunity for planned maintenance, and also restrict the minimum possible turndown to that of a single boiler module.

The simplest confi guration is to completely replace all the boilers in the plant with condensing ones and reduce the system hot water supply temperature to meet the load. Under this confi guration, with the use of high-mass boilers it is possible to operate a variable-fl ow-primary system with a single set of primary pumps to distribute water to the entire building. This option will yield the highest effi ciency as the entire boiler plant would be condensing and the system would experience only the pumping energy required to meet the load. However, this option has the highest fi rst cost as condensing boilers are more expensive than similar-sized non-condensing boilers. …

A condensing boiler; also known as a condensing hot water heater although referred to as a boiler in this article, is a type of boiler that is much more efficient than the traditional type appliance. Extra efficiency is achieved by extracting more energy out of the flue gas as compared to that of a conventional boiler and using this energy to pre-heat the return water flowing into the boiler.

Condensing boilers in practice : Dr Paul Bannister

By contrast – as is visible in the non-condensing section of the performance – non-condensing boilers have a fairly constant combustion efficiency across all gas input levels. Standing Losses The standing losses for a hot water system are proportional to the temperature difference between the hot water and the air surrounding the pipes.
