Central Heating System Explained | Working Procedure and Types

A central heating system is a heating arrangement for an interior space. It’s called a central heating system because it ensures even distribution of heat to all the rooms in a house from a central point, which is the main source of heat.

Central Heating System Explained

The heat gets evenly distributed with the help of a network of pipes. This network of pipes can be linked to each room with the help of a radiator. For under-floor heating, this network of pipes lopes under the floor. No matter which way the installation has been made, even, gentle and thorough distribution of heat in your home is guaranteed.

Central Heating System Explained: How the system works?

A central heating system follows a circular movement which forces hot water out of the boiler to the heating elements, and water comes back to it for gathering more heat. This water takes a circular route and keeps moving, heating an interior space until the system is switched off or the water is flushed out.

Central Heating System Explained

Here are the basic steps-

  • The entry of fuel into your house takes place from a storage unit or external source.
  • The fuel then burns for heating the boiler, which triggers the creation of flaming jets for heating up a water-containing copper pipe. The back and forth movement of this copper pipe over and around the jets heats it up, and the heat from the pipe gets transferred to the water inside.
  • The hot water is pushed through the system with the help of an electric pump.
  • Water moves around the closed circuit distributing hot water to the radiators fitted to the system through the network of pipes. When the water enters the radiators from one side it remains hot but by the time it leaves them from the other end, the temperature of water goes down. All the cooled down water that leaves the radiators then reaches the boiler to get heated up again.
  • A thermostat kept in some communal area of the house monitors the activity of the boiler. When the temperature falls below the set measure, the boiler gets switched on. The boiler gets turned off even when the temperature rises above the thermostat setting.
  • Gases in the form of by-product leave the boiler via a flue.

This was Central Heating System Explained in an awesome manner. Now, you probably understand its functionality better.

In general, everyone, who has a heating system at home, understands that its primary job is to heat the house. But no one really knows how a central heating system heats an interior space.

Understanding how your heating system works helps you immensely at the time of certain crises. At least, it enables you to explain to your plumber or heating engineer the problem your system is experiencing. With central heating system explained so well here, you won’t feel at a loss while talking to your plumber when you need to get the system repaired after it has ceased to work.

When it comes to having Central Heating System Explained, how can the installation part be left out?

Central Heating System Explained

Central heating installation is not an easy job. It needs careful planning and proper understanding of the system and necessary tools and equipment. You can go DIY up to choosing the radiators and the boiler, and also laying the pipes or installing the control system, sometimes. But when it comes to connecting the gas supply with the boiler or checking the installed system for the safety of use, effectiveness, and efficiency, professional intervention is indispensable. Below, you find the steps for installing a central heating system.

Central Heating System Explained

  1. After you have had Central Heating System Explained to you by your heating engineer or plumber, you have probably made up your mind to contribute a little in the selection of components and equipment needed for the installation of the system. Well, that’s good. But make sure you have done all the necessary research.
  2. Devising a map of the Central Heating Installation is always important. This will guide you through the installation of separate components of the system.
  3. Purchase every item necessary for the installation process in consultation with the engineer.
  4. If you have had Central Heating System Explained to you by someone, then you probably know that there is no harm in starting the installation task from the radiators. Your radiators need to be mounted at a height of around 10 to 15 cm (4 to 6 inches) from the floor. So that there is enough room for the valves to the pipes, and also for cleaning. Use a lockshield valve for the return connection and a wheel valve for the flow connection. This will help you with the regulation of the flow of water.
  5. Now, the pipes from the faucets and the radiators to the boiler need to be laid. Copper pipes with capillary or compression joints should be used. You can prevent damage to the system, and airlocks by ensuring that the pipes are venting to the radiators.
  6. Now, it’s time for the installation of the control system. For this, you must follow the manufacturer’s instruction guide because different brands offer different guides having installation instructions and Central Heating System Explained.
  7. When it’s time to install the boiler, you must shut the gas supply and the water off. Again follow the manufacturer’s instruction guide with Central Heating System Explained, for direction, as different manufacturers may have different boiler installation instructions. Don’t attempt at connecting the gas main to the boiler. This part needs expertise; so, get it done by an expert.
  8. Only after closing the radiator vents, filling water into the system, and allowing radiators to vent through, you should commission the system and call Central Heating Installation complete.

Central Heating System Explained: Coming to the Types-

There are two major types of central heating systems- Gas Central heating System and electric central heating system. Now let’s delve deeper into both electric central heating system and Gas Central heating System for some generic knowledge-

Electric Central Heating Systems-

They can be used as an alternative to small and medium-sized boilers. With the advancement of technology, they are getting more sophisticated, and today we find electric boilers that are efficient in heating large homes as well.

They are light, compact and small in size. The number of components needed for this system is less. They make no noise and are cent-percent efficient. They are a newcomer in the industry and are mostly found in rural areas where gas or oil supply is limited.

However, since electric central heating systems are eco-friendly, they are being incorporated into new housing projects being undertaken in cities as well.

Hence, if you have a Gas Central heating System at home, it would be wise of you not to try to convert it into the electric version. For more efficiency, you can replace your boiler with a more sophisticated, modern and efficient one. So, weigh all the pros and cons before going for this heating system.

Gas Central heating Systems

Gas heating systems are probably the most widely used heating system in the world. This system is also referred to as the wet system, where a boiler heated with gas fire warms up the water, which disseminates heat with the help of radiators and hot water running from the taps of your home. Delve deeper with these details-

Central Heating System Explained

A constant natural gas supply streams into the gas boiler. The supply is from a gas main in the street that reaches the boiler through a pipe. The jets of gas heat up a pipe having cold water in it, up to 60 degrees Celsius. This pipe is only a small part of a large circuit of pipes. And it is this network of pipes that travel around your home. After having passed through all the radiators, water reaches the boiler again. When it passes through the radiators, it loses some of its heat; and it is this lost heat that warms up the room in which the radiator is located. The boiler never stops working as it needs to keep the water hot. This flow of water around the house is triggered by an electric pump.

Central Heating System Explained

Systems that are not connected to a gas main in the street are often fuelled by LPG or oil. Although these two are also good options, they are not budget friendly.

There are many varieties of central heating systems available in the market, some of the most common ones include-

  • Combination or Combi boiler system
  • Combi boiler system
  • Conventional gravity fed or Regular system
  • Mains pressure or System boiler

All of these have different features and work differently. And your choice should hinge on your requirements and not on what the current trend says.
