2. Electric boiler - Wikipedia

   en.wikipedia.org/wiki/Electric_boiler

   In places where electric power is relatively low cost compared to fossil fuels, it may be economically practical to use an electric boiler for steam central heating. For example, in Winnipeg, Canada, during the Second World War, large central electric steam boilers were used for a district heating system, using surplus hydroelectric power. The ...

3. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   Air convection heating systems have been in use for over a century. Older systems rely on a passive air circulation system where the greater density of cooler air causes it to sink into the furnace area below, through air return registers in the floor, and the lesser density of warmed air causes it to rise in the ductwork; the two forces acting ...

4. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   Circulating hot water can be used for central heating. Sometimes these systems are called hydronic heating systems. [22] Common components of a central heating system using water-circulation include: A supply of fuel, electric power or district heating supply lines; A boiler (or a heat exchanger for district heating) which heats water in the system

5. Heating system - Wikipedia

   en.wikipedia.org/wiki/Heating_system

   Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps. [1] [2] Distributed heating systems: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters ...

6. Hypocaust - Wikipedia

   en.wikipedia.org/wiki/Hypocaust

   Hypocaust under the floor in a Roman villa in Vieux-la-Romaine, near Caen, France. A hypocaust (Latin: hypocaustum) is a system of central heating in a building that produces and circulates hot air below the floor of a room, and may also warm the walls with a series of pipes through which the hot air passes.

7. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   Electric heat can be accurately applied at the precise point needed in a process, at high concentration of power per unit area or volume. Electric heating devices can be built in any required size and can be located anywhere within a plant. Electric heating processes are generally clean, quiet, and do not emit much byproduct heat to the ...
