Condensing boiler or low temperature boiler - Renovia

Condensing boilers are designed in such a way that the flue gases can largely condense in the heat exchanger, so that that heat is recovered. These gases are lost in a conventional boiler. A low temperature boiler keeps the water on average at 35 to 40 ° C - in contrast to 70 to 85 ° C with a traditional boiler.

Jeff Howell's Tips for Central Heating

They say condensing boilers don't work efficiently on low heat. Condensing boilers only really condense properly (thus extracting the waste heat from the flue gases) at a water return temperature of 54C to 56C. This is usually achieved by having a flow temperature (ie the water flowing out of the boiler) of around 70C.
