Most boilers combust some type of hydrocarbon fuel such as natural gas, heating oil, heavy fuel oil, coal, biomass, or petroleum coke. The fuel must either be stored on site or stored offsite and input by a pipeline.
The energy source is the same as for heating anything. Gas,Electricity, Burning any fossil fuel. in a boiler (furnace) with water running in heat exchanging coils or manifolds. When heat is needed a pump circulates the hot water through the radiators and back to the furness.

Isobaric heating is heating by adding only heat energy while maintaining the same pressure (isobar). Isothermal heating is heating by adding only pressure and no heat energy.
There are many different ways to use radiant energy to heat your home including radiant flooring, radiant electric heating, radiant tiles... The site in the related links has tons of information on radiant heating. Technically, "radiant" heating is used to distinguish from "forced air" systems. In a radiant system the radiant elements emit heat and in an forced-air system the furnace heats air, which is then moved to where the heat is needed. A radiant system can be electrical, hyrdonic or steam-driven. For instance, a hydronic boiler heats water to about 180 degrees and uses circulators (forced hot water) to move the heated water to a finned-tube, floor-tubing, wall-tubing, or cast-iron radiator, heating the radiator, radiating heat into the room. The cooled water then flows back to the boiler to be heated again.
Air may be heated using steam, hot water, electrical resistance, warmer air, the warm earth, or a furnace.

Steam heating is a legacy system left over from previous generations. It's less efficient thant modern heating systems. However it's often not economical to rip out a steam heating system and then replace it.
The pips in a steam heating system need to be insulated to prevent condensation. Condensation can lead to mold and or freezing of the steam pipes in the winter.
In a steam heating system, the pipes transport steam or water vapor to the radiators to heat the building. Insulating the pipes reduces the amount of heat lost to the surrounding environment. Any heat lost in the pipes cannot be used to heat the radiators, and causes the system to be less energy efficient.

Who was responsible for moderizing the railroad and inventing the steam boiler furnace
Geothermal energy uses the heat of the Earth to boil water to steam and convert the steam to electricity and/or heating. No fuel means no emissions. No emissions means no pollution.
ACCORDING TO PHYSICS :- Since the latent heat of vaporisation of Steam is so high as 2268 Joules , thus so as to convert from the Gaseous State to liquid Sate , Steam liberates 2268 J/Kg of heat energy to the Surrounding. In this way it proves more efficient to use Steam than Electricity for heating.
An operating system aquastat senses and controls the temperature of the water in a heating system.
