Boilers are generally used in homes for getting hot water and warming up houses in cold temperatures, but this is all that a normal boiler does. A boiler has its different types and further its subcategories which make it a little complicated to understand boilers for a normal person.
Boilers are also widely used in commercial areas where the output of boilers is massive as compared to normal compact-sized house purpose-built boilers. Boilers are versatile you can enjoy dozens of features by attaching different components to a boiler in order to get your desired features.
In this article, I will talk about Boiler Repairs Dagenham and their major types to understand that how different they are from each other.
What are boilers?
A boiler is a closed vessel in which water is heated. The water doesn’t automatically boil. The heated or vaporised water exits the boiler for its usage in several processes or other heating applications.
What is the working process of the boiler?
A boiler requires fuel in order to operate, and it utilises oil, gas or electricity to produce heat. This fuel is used to heat the water inside the boiler. The hot water or steam is sent forward to your entire home (using radiators), where it makes the air warm and feels cosy.
Different types of boilers:
A boiler has its complete family of diverse types of boilers.
There are 3 main types of boilers
- Combi boilers (combination boilers)
- Heat only boilers
- System boilers
Classification of boilers
- Water tube boilers
- Cylindrical fire tube boilers
- Multi tube boilers
- Firetube boilers
- Haycock and wagon top boilers
- Solid fuel firing
- Supercritical steam generator

Combi boilers (combination boilers):
Commonly known as combination boilers because they were mainly made to combine all parts of a conventional central heating system into a small unit. A combi boiler is a type of boiler which provide us with both hot water and central heating for homes.
Modern combi boilers come up with a pre-heat system which allows the combi boiler to preserve a small quantity of water which can extract from the boiler. The water is managed inside the boiler and set at your desired temperature all day long.
Heat-only boilers:
A heat-only boiler, commonly known as an open vent boiler, is basically a system comprising 2 tanks, a hot water cylinder and the boiler itself. Heat-only boilers are generally installed in commercial areas so they can easily meet the demand of hot water in numerous waters taps and showers.
Heat-only boilers work by heating water and delivering it all over the house by mainly using a system along several controls, involving the parts like pumps tank and motorised valve. A cold-water tank reserved in the loft, will use water from the main and provide it into a hot water cylinder.
System boilers:
A system boiler is also an important type of boiler which is generally installed in large houses with huge demands of space heating and hot water. After installing the separate cylinder in order to store water, system boilers are the perfect choice for providing a consistent supply of hot water all over the house, unlike the combi boilers, that can only heat the water on demand.
Maintenance tips for boilers:
A boiler’s life can be extended by following these maintenance tips.
- Check out the boiler water pressure
- Inspect your boiler’s water cylinders.
- Bleed the radiator every season (to avoid any blockage in the boiler).
- Place your boiler in a space where ventilation is good.
