System boiler and hot water cylinder

What Is A System Boiler?

Your search for a dependable heating and hot water system for your larger London home ends with a system boiler. These boilers are engineered explicitly for homes with higher demands for hot water and heating.

System boilers store hot water in a separate cylinder, ensuring an uninterrupted supply of hot water throughout the house. Unlike combi boilers that heat water on demand, system boilers can provide hot water to multiple taps and showers simultaneously.

One of the most significant advantages of a system boiler is its ability to maintain consistent water pressure. Thus, it’s an ideal option for homes with multiple bathrooms or high hot-water consumption.

System Boiler FAQ

How Does A System Boiler Work?

A system boiler is a type of central heating boiler that works by heating water and then storing it in a separate cylinder. The stored hot water can then be used to provide hot water for taps and showers throughout your home.

When the heating system is turned on, the system boiler uses a heat exchanger to heat the water that flows through the pipes in your home’s radiators. This heated water then returns to the system boiler to be reheated and circulated through the radiators again.

The hot water for taps and showers is stored in a separate cylinder that is often located in an airing cupboard. This cylinder is usually insulated to help keep the water hot and ready for use whenever you need it.

System boilers also have an expansion vessel, which is a small tank that is attached to the system to accommodate any increase in volume of water that occurs when the water is heated. This helps to ensure that the system remains at the correct pressure and prevents damage to the boiler and heating system.

System boilers are a popular choice for larger homes with higher hot water demands, as it provides a constant supply of hot water to multiple outlets simultaneously.

What’s the difference between a regular boiler and a system boiler?

What Makes System Boilers Different from Regular Boilers?

When it comes to heating your home, choosing the right type of boiler is crucial. But what are the key differences between a regular and a system boiler?

A system boiler is designed as an all-in-one unit that doesn’t require any extra tanks or cylinders. This means it’s often quicker and easier to install than a regular boiler, making it a popular choice for homeowners who want hassle-free heating. In contrast, a regular boiler may need a header tank in the loft to supply hot water to the cylinder and keep the radiators topped up with water.

Overall, both types of boiler have their advantages and disadvantages, so it’s worth doing your research before making your final decision.

What’s the difference between a system boiler and a combi boiler?

Combi Boilers vs System Boilers: Which One Do You Need?
If you want instant hot water and heating, a combi boiler is your best bet. But if you need a system that can work with a cylinder to supply hot water, then you should go for a system boiler. This type of boiler comes equipped with an expansion vessel and pump for use in sealed systems.

What are the advantages of a system boiler?

Why Choose A System Boiler?
When it comes to choosing a boiler for your home, a system boiler is a great option. For starters, they don’t require a cold water tank. Instead, they can be used with pressurized/unvented hot water cylinders, which saves space in your home. Even if you don’t have a loft, you can still install a system boiler.

Easy Installation – Another advantage of system boilers is that they’re easy to install. This is because most of the components are built into the system boiler itself.

Multiple Taps – With a system boiler, you can use multiple taps or showers at once without any reduction in water pressure.

Disadvantages of System Boilers
Takes up Space – While system boilers don’t need a cold water tank, they do require a hot water cylinder. This can take up quite a bit of space in your home.

Limited Hot Water – The amount of hot water you have is limited to the size of your hot water cylinder. Once you run out, you’ll have to wait for it to heat back up.
