In this article, our focus shall be two of the most commonly used heating mechanisms in households across countries where the winter hits hard. These are namely the furnace system and the boiler system.
Furnaces-
Furnaces are very common in North American households and a majority of the population depend on a central furnace for the provision of heat. A furnace blows heated air through ducts in the house. These ducts carry the warm air to the rooms in the domestic space via air registers or grills.
The furnace is usually fired by gas or oil. The fuel is basically mixed with air and is allowed to burn. A metal heat exchanger is heated by the flamed in the furnace, and the heat, having mixed with air, is transferred via it. The furnace fan ensures that the heated air is pushed through the heat exchanger, through the ductwork and downstream of the exchanger. The by-products of the process of combustion are then vented out of the building via flue pipes.
Boilers-
These are efficient and effective water heaters. It is different from the heating furnace system with respect to the carrier of the heat. In case of the furnace, the heat is carried via water. Water is the primary carrier of heat here. So as the water passes through the radiators in the system, it gives up heat. The water can pass through other devices in the domestic space that can make use of the heat.
The cool water is then returned to the boiler where it is heated again for reuse. This system is also known as hydronic system. The fuel that is commonly used in domestic boilers is either natural gas or heating oil. Unlike the furnace, the boiler does not use a fan or a duct system to circulate the heat throughout the house. A boiler uses a pump to circulate the heat in the water. For emergency boiler repair in Wigan, consider Kamdem Home tech.
