System boilers
A system boiler is a type of boiler that works with a separate hot water cylinder to provide heating and stored hot water for your home.
They are often a good option for larger homes in Sheffield, Dronfield and nearby areas where more than one tap, shower or bathroom may be used at once.
Unlike a combi boiler, a system boiler stores hot water in a cylinder rather than heating it instantly on demand.
This page explains how system boilers work, the main benefits, when they are suitable and what to consider before choosing one for your home. If you are thinking about replacing your boiler, Love Your Boiler can also advise whether a system boiler is the right option for your property.

Why choose a system boiler?
System boilers offer several practical benefits, especially for homes with higher hot water demand or more than one bathroom.
Strong water pressure
A system boiler can provide stored hot water for busy homes where several taps or showers may be used close together.
No loft tank needed
Unlike regular boilers, system boilers usually take water directly from the mains and do not normally need a cold water tank in the loft.
Good for large homes
System boilers are often well suited to larger properties where a combi boiler may struggle to keep up with hot water demand.
Efficient setup
Many key parts are built into the boiler, helping keep the system neat while supporting efficient heating and hot water performance.

Is a system boiler the right fit for your home?
System boilers are often a good choice for homes with multiple bathrooms, higher hot water use or an existing hot water cylinder. They can be especially useful where more than one person may need hot water at the same time, such as during busy mornings.
However, a system boiler may not always be the best option for smaller homes or properties where space is limited. Because the system needs a hot water cylinder, it takes up more room than a combi boiler.
