What are the different types of boilers?

October 14, 2020
Boilers come in three main types and are chosen depending on the size of the property, the number of bathrooms/showers, the water pressure in the locality, and the needs and demands. Here is a look at the different kinds of boilers:

Condensing Boilers

Condensing boilers make use of two different heat exchangers. While one is used for heating the water before it is released through the pipes to heat the radiators, the other exchanger reheats the water that returns from the circuit of pipes in the home.

Condensing boilers make use of energy from the exhaust gases to preheat the water to the boiler. This ensures increased energy efficiency as compared to non-condensing ones.

Condensing boilers are incredibly efficient and can lower your utility bills as well as your carbon footprint. Condensing boilers are almost 90% energy efficient. 

Condensing boilers are of three main types:

  • Combi boilers
  • System boilers
  • Conventional which are also known as regular or traditional boilers, open vent or heat only boilers

Combi Boilers

These are probably the most cost-effective option for most homes. Combi boilers can provide both hot water as well as central heating. These heat water directly from the mains, thus providing you with an unlimited supply of hot water whenever needed. These boilers do not require a separate cylinder or water tank. 

These provide a lot of benefits thanks to their compact size, quick installation, and easy maintenance. These are extremely energy efficient and are environment friendly.

System Boiler

For homes with multiple bathrooms, a system boiler makes the perfect option.

These need a hot water storage cylinder and not a water tank. These have an inbuilt pump and expansion vessel which also eliminates the need for header tanks. The system boilers are a modern version of your regular boiler. 

These are installed alongside the unvented hot water cylinders. A system boiler makes the perfect choice for homes that do not have additional space for a tank.
