Types of boiler systems


Boilers are those wonders of engineering that are used as a heating source or for producing steam. The best part about boiler systems is their different types, functions, and purpose. From homes to factories, boilers have been used for decades by people as a primary heating source. Since boilers are closed vessels where a liquid gets boiled for heat or fuel. This liquid is mostly water in most of the boilers. Boilers have gone through many evolutions, from being used in locomotives run by steam to finding a place in homes and factories.

When it comes to modern boiler systems, there are mainly three types available. The first is ‘Combination or Combi boilers,’ the other is ‘Heat-Only or Regular boilers,’ and ‘System boilers.’ Let’s find out more about them in detail.

What are boiler systems?

Boiler systems refer to the boiling of a fluid in a particular, enclosed vessel that further generates vapour or steam. Boilers, as their name suggests, are highly functional in boiling fluid, mostly water, in large quantities. A boiler’s heating process is quick, requiring a lot of energy, and the hot water or steam keeps circulating through the piping system. The output of boiler systems is used in the process of power generation, heating, and many others. Speaking of systems, have you ever wondered about how smart heating systems work?

Types of boiler systems

While talking about the types of boiler systems, there are three types, combi, heat-only, and system boilers. At the same time, boiler systems can also be classified according to the materials used in their production. Let us first classify the boiler systems according to their materials.

Water-Tube Steel Boilers- Commonly used in industries, a water-tube boiler is where the water gets boiled and circulated through pipes. The tubes get surrounded by gases that evolved through combustion and enable much steam generation.

Fire-Tube Steel Boilers- You can say that fire-tube boilers are the exact opposite of water-tube boilers. Fire-tube boilers are used for homes or industries, or even commercial purposes. These types of boilers are generally used for space heating and also for steam production. Here, the combustion gases are passed through pipes surrounded by water, the exact opposite of water-tube boilers.

Cast Iron Boilers- These boilers have a single chamber separated by sections that run vertically and horizontally. Its functions are similar to a general boiler.

What type of boiler is best?

Choosing the correct boiler is quite an easy task based on your requirements. Combi boilers with a condensing system are the best choice if you need a boiler for your home. Combi boilers are ideal for unlimited water supply or central heating but are also cost-effective and energy-efficient.

Combi boilers can be easily installed in homes and are the best choice if you do not need a hot water supply for the whole day. Since combi boilers are eco-friendly, you will only get hot water for specific times and through one tap at a time.

If you live in a home with multiple bathrooms and the requirement for a hot water supply is high, then system boilers are just the right ones. System boilers are excellent for homes needing high water from unlimited hot water supply for multiple taps to energy efficiency. System boilers are also easy to install and come with a hot water cylinder, so no additional cylinders are needed.

Since all the modern boilers you see today are condensing, you can also opt for condensing conventional boilers for regular usage. They are energy efficient; however, they need a lot of space to install, and even the installation is expensive. But once you install a conventional boiler, you don’t have to worry about low water pressure or multiple tap supplies.

Precisely, for smaller homes, the best boiler would be Combi boilers. However, if your homes are large and have multiple bathrooms, tank-based boilers, such as Conventional or System boilers, can only fill the requirements.

Common boilers

People mainly recognise boiler systems based on their purpose. The most common boilers are primarily classified into three types:

Combination or Combi Boilers- The most popular boiler used across the United Kingdom, Combi boilers provide hot water or help in heating spaces. As a result, it is ideal for places with harsh winters. Combi boilers are available in two options; you can choose an electric combi boiler or one that runs on gas.

System Boilers- Also used for unlimited hot water supply, system boilers are also recognised as sealed boilers. The best part about system boilers is that they come with a tank or a water cylinder. So, no additional water tank is needed.

Heat-Only or Regular Boilers- The most common type, heat-only or regular boilers, are most popular in households. These boilers enable unlimited hot water supply from multiple taps, including a tank and a cylinder. Sometimes, these boilers are also called Conventional boilers for their easy use.

Apart from these, there are Condensing boilers. To much surprise, any conventional, combination, or system boiler you see across the United Kingdom is a condensing boiler. Condensing boilers are eco-friendly and energy efficient.
