The metal fins on the outside of the hot water pipes radiate heat into the room.
Mainly by burning wood or coal, but also there were the water/steam heated radiators.
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.
Homes may be heated with any of several kinds of heating systems. These include:Radiant heat from electric radiators,Radiant heat from steam or hot water circulated through radiators and heated with gas, propane, oil or coal fired boilers,Hot air circulated through the home and heated by gas, propane or oil fired furnaces,Solar heating systemsWood or coal burning fireplaces.
Radiators produce heat by transferring thermal energy to the surrounding air in a room. They are part of a heating system that uses hot water or steam circulating through the radiator to warm up indoor spaces.
Radiators transfer heat by electromagnetic waves. The sun waves/rays send electromagnetic waves.
Steam RadiatorsElectric RadiatorsTraditional radiators are powered by steam or hot water. Aboiler in the basement of a building heats pressurized water to an extremely high temperature, turning it into steam. As the water turns into a gas, it expands and becomes less dense, which causes it to flow up through steam tubes into radiators in the building. As the water flows through tubes inside the metal radiators, some of its heat is transferred into the metal. This gives the radiator the heat it needs to warm the room and cools the water, which then flows back to the boiler to be heated again.Electric radiators are powered by a heating element. Heating elements are actually specialized resistors--devices that resist the flow of electricity. When electric energy flows into a resistor, it is turned into heat. The heating element in a radiator is usually suspended in oil, which conducts the heat away from the element. The heat then flows out into the metal body of the radiator and from there, into the room.
Other wise heat loss will occur and the radiators wont be as hot.

In a steam heating system, energy is transferred from the steam to the surrounding air or objects through conduction. The steam gives off heat as it condenses into water, warming up the radiators or pipes in the system, which then heat the space through convection and radiation.
Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in automobiles, buildings, and electronics. The radiator is always a source of heat to its environment.
A heating system that uses radiators to transfer thermal energy is typically a hydronic or steam heating system. In these systems, hot water or steam circulates through the radiator to transfer heat into the room. The radiator then emits heat into the surrounding space, providing warmth.
Usually by being used to heat a steam heating system.
