Also known as hydronic heating; a type of central heating system that uses hot water to deliver heat from a central boiler to the rooms throughout a building. The heat is radiated into each room with hydronic baseboard or radiators. Hot water heating is often seen as a more gentle, quiet and even heating system than forced air systems. But it has a disadvantage that if central air conditioning is desired, a ductwork system must be added only for cooling. It can also be easily zoned, thus allowing individual temperature control for different areas of the home. A hot water heating system is typically more expensive to install, but often has a longer life.
