The efficiency of a fossil-fuel furnace or boiler is a measure of the amount of useful heat produced per unit of input energy (fuel). Combustion efficiency is the simplest measure; it is just the system’s efficiency while it is running.
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 or radiant floor systems, or can heat air via a coil.
A system boiler is a closed system that only requires a boiler and a cylinder, whilst a regular boiler requires header tanks in the loft to feed the hot water cylinder and to maintain the water level in the radiators.
12-03-2020· System boilers take water directly from the mains and heat it in a single storage cylinder. This water is then distributed to radiators, taps and showers. As a result, you get hot water on demand almost instantaneously. The only drawback is that hot water cylinders can only hold a certain amount of hot water at any one time.
Boiler Systems Operation In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
OverviewA boiler is an enclosed vessel that provides a means for combustion and transfers heat to water until it becomes hot water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. Water is useful and cheap medium for transferring heat to a process.
