A Guide to Understand the Working of Central Heating System

An efficient heating system is a must-have thing in any house to make sure the ultimate comfort in winters. Households have to call experts for repairing the heating system even if there is a minor fault in its functionality. However, you can easily understand the functionality of heating system because it is not very complicated. So, you will also not have to pay high charges to experts for small repairs and if you call them for major repairs, you can judge their work as well. More on, you’ll also come to know immediately whenever the system will need maintenance because those who know how it works can identify the faults during the inspection. Here in this article, a guide is provided to help you understand the working of central heating.


The Working of Boiler

The main part of any heating system is a boiler and it works through a natural streaming. Switching on the boiler will let the house to get heat because, in this process, gas enters when the valve is opened and later, it enters through some small jets and goes straight to the sealed combustion chamber. A heat exchanger collects the cold water from a pipe that has a connection with the water supply and then it heats up the water to approximately 60 degrees. The gas jets provide the heat energy to the exchanger and this is the main step towards how central heating works. The water pipe is then connected to all the sections which provide water to the whole house. This is all about the circulation of water as the boiler heats up the water and passes it through the hot-water radiator.

The Working of Central Heating

The central heating basically works as a continuous circuit because it delivers hot water out of the boiler by passing through radiators and later the excess of water is sent back to the boiler for more heat. This process is a bit convoluted as there is a series of pipelines that separates out the cold and hot water. The parallel branches and trunks also play a role and the water is sealed in the system for a daily use. More on, the heat is also stored in a form of chemical that makes the system more efficient to work.

The Role of Heat Exchanger

The heat exchanger works when the boiler burns the gas and there are some copper pipes that contain water and move it back and forth to several times so that water does not cool down even for a while. So, in short, the heat exchanger makes sure to provide the heat on a continuous basis. An electric pump is also included in the system that circulates the water efficiently. The radiator’s main role is to provide heat to the whole house and it gets heat from the hot water. When the hot water circulates through each radiator, it delivers its heat to them and when it becomes cold, the boiler provides more heat to water and this is how the heating process continues all the time.

How Does Thermostat work?

The thermostat is the only system in the whole heating system that can be controlled manually. You can turn it off whenever you feel hot and it can be turned on when you feel cold. However, some automatic thermostat programs are also now introduced that control the temperature automatically. These electronic programs control the working in a way that system turns on automatically during certain times of the day and turn off when you aren’t at home. It is quite effective to save the energy. More on, if you prefer to control it manually then it is good to install the thermostat in your living room because it does not occupy large space.

Is Gas the Only Fuel to run Boiler?

It is the commonly asked question and yes, you should definitely know regarding the choices of fuel as well. The heating system is designed with two parts, radiators and boilers. You have the option of both gas and electric boilers, so you can replace them anytime. However, replacing the boiler is not recommended as it is always full of water so it needs some special techniques to be replaced.
