What is Central Heating?

Explanation of central heating

Central heating is a system that provides warmth and comfort to an entire building or a specific area from a centralized source. It consists of a main heating appliance, which is usually a boiler, that heats water or air and distributes it throughout the building via a network of pipes or ducts. This ensures a consistent and even distribution of heat, making it a popular choice for residential and commercial properties alike.

How central heating works

Central heating systems work by generating heat in a central location and then distributing it throughout the building. The most common type of central heating system is a wet system, which involves heating water in a boiler and then circulating it through radiators or underfloor heating pipes to release the heat.

The boiler burns a fuel source, such as gas, oil, or electricity, to heat the water. The heated water is then pumped through a network of pipes to the radiators or underfloor heating system. As the hot water passes through the radiators or pipes, it transfers heat to the surrounding air, warming up the room.

Importance of Central Heating

Oil central heating systems utilize oil as the fuel source for the boiler. This type of system is more commonly found in rural areas where other fuel sources, such as gas or electricity, may be less accessible. Oil central heating provides reliable and efficient heating, especially for properties located off the main gas grid.

Renewable energy central heating

Renewable energy central heating systems, such as heat pumps and solar heating systems, utilize sustainable and environmentally friendly energy sources to provide heat. Heat pumps extract heat from the air, ground, or water, while solar heating systems use energy from the sun to heat water or air. These systems are gaining popularity due to their low carbon footprint and long-term cost savings.

Components of a Central Heating System

A central heating system consists of several essential components that work together to provide efficient and reliable heating. These components include boilers, radiators, pipes, thermostats, and expansion tanks.


Boilers are the heart of a central heating system. They generate heat by burning fuel or using electricity. Boilers come in various sizes and types, depending on the heating requirements of the building. It is crucial to choose the right boiler size and type to ensure optimum performance and energy efficiency.


Radiators are the most visible components of a central heating system. They are responsible for releasing the heat generated by the boiler into the surrounding air. Radiators come in different sizes and designs, allowing you to choose the ones that best suit your interior style and heating needs.


Pipes form the network that carries hot water or steam from the boiler to the radiators or underfloor heating system. They also return the cooled water or condensate back to the boiler. The pipes must be properly insulated to minimize heat loss and maintain the efficiency of the system.


Thermostats are devices that allow you to control the temperature of your central heating system. They regulate when the boiler should fire up to maintain the desired temperature. Modern thermostats often have programmable features that enable you to set specific heating schedules, resulting in energy savings.

Expansion tanks

Expansion tanks are used in sealed central heating systems to accommodate the expansion and contraction of the heated water. As the water heats up, it expands, and the expansion tank acts as a pressure relief valve to prevent damage to the system.
