What Is a Boiler?
A boiler is a system that heats up water and sends it circulating throughout your home to heat your rooms. It also provides hot water for use on your taps and in your showers. In London, having a functioning boiler is very crucial, particularly during winter.
There are three different types of boiler: combi, system, and regular boilers. They work a bit differently, and you can choose one once you know the differences.
Combi Boilers
Combi boilers are the most prevalent boiler type to be fitted in London homes. Combi boilers are small, simple to fit, and cheap. A combi boiler both heats and provides hot water. It accomplishes this by heating water as it is required, and does not store it in a tank.
How Does a Combi Boiler Work?
A combi boiler also heats water on demand whenever a shower or a tap is turned on. It never stores hot water at any time in a tank and thus conserves space. It ceases to heat water when the shower or the tap is turned off. It is suitable for small homes or flats since there is not much space.
Advantages of Combi Boilers
Space-saving and energy-efficient: No need for a hot water tank.
Instant hot water: You have the hot water available at your disposal when you need it.
Energy-efficient: It will only heat the water that you are using, and this cuts down on your energy bill.
Cost-effective: The combi boiler is cheaper to install than any other.
Combi Boiler Disadvantages
Water pressure problems: The low water pressure in your home malfunctions the combi boiler.
Big families: A combi boiler cannot give hot water to two taps at once
When to use a Combi Boiler
A combi boiler will be perfect for small to medium-sized homes, or a flat, with one or two bathrooms. If you have little space and you don’t want the hot water piped out from more than one tap at once, it’s perfect.
System Boilers
System boilers are ideal for large homes. They heat and provide hot water, but store the hot water in a tank. Much of a standard boiler is pre-fitted, i.e., easy to fit.
How Does a System Boiler Work
A system boiler heats the water and stores it in a hot water cylinder. This gives you instant hot water at any point in time. As the system is more powerful than a combi boiler, it can deliver hot water to many showers or taps at the same time.
Disadvantages of System Boilers:
Harder to install: Harder to install as it requires a hot water cylinder.
Greater water pressure: Can heat water for more than one tap at a time.
No room for a cold water tank: Compact.
Energy-efficient: Uses less energy than conventional boilers.
Disadvantages of System Boiler:
Space required for a hot water cylinder: You will have to find space where you can fit the cylinder.
It is expensive: Expensive to install compared to a combi boiler.
When to Use a System Boiler
A system boiler is ideal for larger homes with over one bathroom and enormous hot water needs. It is a great option for you if you are a large family or need hot water simultaneously from over one tap.
Regular Boilers (Traditional Boilers)
Regular boilers, or conventional boilers, are most widely used. Regular boilers boil water and store it in a tank. Regular boilers also require a cold water tank. Regular boilers can usually be fitted in older homes, but can be installed in exceptional cases.
How Does a Regular Boiler Work?
Regular boilers boil water in a cylinder and retain it. Cold water is sourced from another tank, usually in the loft. Hot water for central heating and shower, and tap hot water.
Advantages of Regular Boilers:
Suitable for large houses: Can offer the higher temperature needed for hot water in large houses.
Multiple taps: It can warm water in more than one tap or shower at the same time.
Space-consuming: You need a hot water cylinder and a cold water tank, which occupy space.
High installation cost: It is expensive to install a conventional boiler because it requires extra space and fittings.
Energy-negligent: They consume a lot of energy as opposed to combi or system boilers.
When to Install a Traditional Boiler
A standard boiler will be ideal for a large house with lots of bathrooms and an enormous hot water need. It will be perfect if you desire a system that can create plenty of hot water at once.
