Regular boilers, combi boilers, and system boilers are the three basic types of household boilers. Each of them has its own set of characteristics and benefits, making them suitable for various types of properties. This article seeks to highlight the essential characteristics of each boiler type, as well as their benefits and applicability for various families. If you want to learn more about which boiler is ideal for your house, keep reading to learn about the features that each option has to offer.

Types of Boilers

Prior to making any selections regarding the type of boiler that is ideal for your home, make sure you have a thorough understanding of the options available. We install a wide range of boilers of all sorts, brands, and sizes at all heating one, so we’re more than capable of giving you the information you want. Here’s all you need to know about the three types of boilers:

Typical Boilers

Regular boilers sometimes referred to as conventional or heat-only boilers, are the most common type of house boiler system found in older homes. These boilers heat your home through radiators while also storing hot water in a separate cylinder. A second storage tank for cold water is also available.


  • Can supply hot water to numerous taps at the same time
  • A popular option for homes that already have a standard central heating system.
  • Frequently include a ‘back up’ electric immersion heater to guarantee that you have hot water even if the boiler stops.

Combi boilers

Combi boilers, often known as “combination,” boilers, are high-efficiency boilers that supply families with both instantaneous hot water and efficient central heating. The small size and multi-purpose functionality of these boilers make them a popular choice among homeowners.


  • The compact design eliminates the need for a water cylinder or tank, allowing for space savings.
  • Water that is instantly heated
  • Only heat the water that is consumed, allowing for possible cost savings.

System boilers

Regular and combi boilers are like system boilers. Like regular boilers, they store hot water in a separate cylinder and, like combi boilers, are small with most components built-in. System boilers are built to supply efficient heat and big amounts of hot water on a massive scale.


  • Provides continuous hot water to several taps at the same time.
  • Most components are integrated; thus, installation is usually quick and simple.
  • There’s no need for a separate cold-water storage tank.

Which boiler is the most suitable for my home?

The supply of heat and hot water is critical to the smooth operation of your home. Therefore, it’s critical to choose a boiler system that meets your family’s requirements. We’ve included some common property types and the boilers we think are ideal for them.

“I have a small or medium residence with a regular hot water demand.” If you can relate to this remark, a combi boiler may be the ideal option for you. Because combi boilers are small and often stored out of sight in a boiler cabinet, they can help you conserve space in your home. These boilers are energy-efficient and can deliver both effective heat and quick hot water without the need for any extra components. Installations are usually quick and painless, however, switching from another kind of boiler may take a little longer. 

“I have a medium-sized residence with a high hot water consumption.”  Is this something you’d like to do with your home? If that’s the case, a system boiler could be the best option for you. Except for an external cylinder for storing hot water, system boilers have most of their components built-in. These boilers have the ability to give effective central heating to bigger buildings, as well as a steady supply of hot water to many taps at the same time, which is very useful if your property has two or more bathrooms.

“I have a medium or big residence with a high hot water demand.”  If this is the case in your home, a conventional boiler may be the best solution for you and your family. Regular boilers are ideal for houses with several people who need hot water at the same time. For example, if you have two or more bathrooms and need hot water to be delivered to various areas at the same time, a regular boiler may be the best option. If your property currently has this type of central heating, replacing it with a standard boiler might be a simple and quick procedure.
