Boilers | Modulating Condensing Boilers

Modulating condensing boilers (mod-con boilers) can increase combustion efficiency to about 96%, up from the 80% efficiency of non-condensing boilers. They provide a range of firing rates to match the variable heating load of the building. However, mod-con boiler efficiency depends on the temperature of the water returning to the boiler.

2013/6/28 · So, I'm looking at heat only non-condensing gas boilers. I've only found one manufacturer of a modulating non-condensing gas boiler so far. Space heat loss is 70k BTU/h and already have a 41 gal. indirect tank heater and my shower useage at only 2GPM (hot only) would indicate DHW load of at least 100k-120k output needed.

Consulting - Specifying Engineer | Retrofitting with condensing boilers

2010/4/1 · Condensing boilers are more efficient than noncondensing boilers only when they operate in the condensing mode. In that mode the thermal efficiency increases from the typical noncondensing efficiency (80% and 87%) to a condensing efficiency that ranges between 86% and 99% or more, depending on the operating parameters and the boiler technology.

(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.
