There are pipes that feed from radiator to radiator. Or there can be multiple feed pipes and return pipes, it varies based on installation.
A forced hot air system warms a house by using a furnace to heat air, which is then circulated through ductwork by a blower fan. The warm air is delivered into each room through vents, raising the temperature in the space. The cycle continues until the desired temperature is reached and the thermostat signals the system to stop heating.
Forced air heating works by the warm air being pumped through the system and pipes so that it radiates the heat out into the room. This is a quicker but more expensive way of heating than convection.
Radiant heating works by transferring heat directly from a warm surface to objects and people in a room. This can be done through electric resistance heating, hydronic heating (using hot water circulated in pipes), or radiant panels. The heat radiates outwards, warming up the surrounding area without the need for forced air or ductwork.
Forced convection. Heat is transferred through the air in the room by the movement of the air from the heating vents.
This is a system where the boiler heated fluid flows by the principle of gravity-flow instead of pumps. This principle requires the distribution system to be sized correctly and installed with accurate slopes for the hot water to rise in and flow to the terminal units.
Are you considering this in a residence? A friend of mine converted a residential steam system with cast iron radiators to hot water for child safety reasons. It all worked, but he had to deal with some water leaks at joints in the radiators. That was a nuisance. The amount of heat delivered to the house will be different with water, but I can't remember if the radiators are oversized or undersized after conversion. In his case it heated fine. Call a professional. EPM
No, in Canada, a forced air heating system is most common as it is relatively low cost source of heating. With a forced air heating system, heat is usually delivered through a metal duct system throughout a house or building.
A boiler is primarily used for heating. Water is heated and forced through pipes to heating receptacles called radiators. Giant boilers are also used for electricity. Water is heated to turn giant turbines that produce electricity.
A central heating unit that combines hot water through radiators and warm air distribution through floor vents is commonly referred to as a "hydronic heating system" with a "forced air" component. This system can provide efficient heating by circulating hot water to radiators while also using a furnace or heat exchanger to warm air for ducted distribution. Such dual systems offer flexibility in heating options throughout a home.
Examples of home heating methods include forced air furnaces, radiators, baseboard heaters, electric space heaters, and heat pumps. These systems use different processes like burning fuel, circulating hot water, or transferring heat from outside to keep your home warm.
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
A forced-air heating system includes fans to circulate warm air throughout the space. The warm air is generated by a furnace or heat pump and distributed through ductwork to different rooms in the building.
A forced hot water heating system is more energy efficient, provides consistent warmth, and is quieter compared to other heating systems like forced air or electric baseboard heaters.
Forced air heating
A boiler heats water to a safe heating temperature, often 180 degrees or so, and when a thermostat calls for heat, circulating pumps move the water from the boiler to the radiators where it heats the air surrounding the radiant surface, causing localized convective heating as well as some amount of conductive and radiant heat transfer. others have said: Stratification HEAT goes to the cold.
"FF" often stands for "fan forced" in the context of heating systems, indicating that a fan is used to circulate air and enhance heat distribution. A boiler, on the other hand, is a heating system that heats water or fluid to provide warmth to a space through radiators or underfloor heating. In some contexts, "FF" might also refer to "freestanding fireplace" or "fireplace insert," depending on the application.
Forced air heating offers several advantages, including rapid heating of spaces due to the efficient circulation of warm air through ducts. It allows for zoned heating, enabling different areas of a home to be controlled independently for personalized comfort. Additionally, forced air systems can integrate with air conditioning and air filtration systems, improving overall indoor air quality. The system is also relatively easy to install and maintain compared to other heating methods.
