The answer to 'difference between boiler and' is that a boiler is a central heating system that uses hot water or steam to heat a home, while a furnace is a central heating system that uses forced air to distribute heat throughout a home. Boilers typically have a longer lifespan and are more energy-efficient than furnaces, but they can be more expensive to install and maintain.
Boilers work by heating water or creating steam, which is then circulated through pipes to radiators or baseboards throughout the home. Furnaces, on the other hand, use a fan to blow heated air through ductwork and vents. Boilers are often better suited for homes with existing radiator or baseboard heating systems, while furnaces are more common in homes with forced-air heating.
