Why does a condensing boiler create a plume

2016-8-7 · Water vapour cooling is via extraction of "sensible" heat and involves a temperature change. Since it is the returning CH water that does the cooling to extract latent and sensible heat then the coolest to be expected in the exhaust is probably around 70 degrees based on a CH return of 55 degrees.
