Introduction to Condensate Recovery | TLV - A Steam
Condensate contains a significant amount of sensible heat that can account for about 10% to 30% of the initial heat energy contained in the steam. Feeding the boiler with high-temperature condensate can maximize boiler output because less heat energy is required to turn water into steam.

What is a Boiler and How Does it Work? | RealPars
Aug 19, 2019 · Boilers are an extremely versatile and important piece of engineering equipment, not only for us on a domestic level but at a commercial and industrial level too. To generate heat, we need a fuel source. The reaction of having a fuel source, heat and an oxidizing agent allows for a reaction to take place. This keeps the heat source going.

Furnaces and Boilers | Department of Energy
Furnaces and Boilers. Image. Most U.S. homes are heated with either furnaces or boilers. Furnaces heat air and distribute the heated air through the house using ducts. Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators

AFUE and Real Boiler Efficiency | Annual Fuel Utilization
AFUE much more closely represents peak efficiency, and the energy wasted when the boiler shuts off really cuts down the annual efficiency. Comparing the 83.5% AFUE tankless coil boiler at right, System 2000 will cut fuel bills by over 43%…although there is only a 4% difference in AFUE ratings. This means the tankless coil boiler will burn 77%
