What is a System Boiler?
A system boiler works alongside a hot water cylinder to store and supply heated water. Unlike traditional boilers, most of the essential components – such as pumps and valves – are built into the unit itself.
This makes system boilers:
- Easier and quicker to install
- More compact than conventional systems
- Ideal for homes without loft space (no cold water tank required)
They are also compatible with solar water heating systems, helping reduce your energy usage and environmental impact.
Boiler Finance Options Available
We understand that a new boiler can be an unexpected expense. As an FCA-regulated installer, we offer flexible finance options to help spread the cost.
How Do System Boilers Work?
System boilers heat water directly from the mains supply and store it in a hot water cylinder for later use. Because of this, they can deliver hot water to multiple taps, showers, and baths at the same time without losing pressure.
This makes them a great choice for:
- Larger households
Homes with multiple bathrooms - Families with high hot water demand

Yes, we install a range of A-rated conventional boilers to suit different homes and heating requirements.
We specialise in:
Combi boilers – ideal for smaller homes, providing heating and hot water on demand without the need for a tank
Regular (conventional) boilers – best for traditional heating systems with a hot water cylinder and cold water tank, ideal for larger properties or homes with older pipework
Our experienced engineers will assess your home and recommend the best system boiler for your home – based on your property size, hot water usage, and existing system.
Yes, system boilers require more space than combi boilers, as they need a separate hot water cylinder to store heated water.
However, they don’t require a cold water tank in the loft like traditional (regular) boilers, making them a more compact option compared to older systems.
System boilers are ideal if you have:
- Enough space for a hot water cylinder (such as an airing cupboard)
- A larger home with higher hot water demand
- Multiple bathrooms needing hot water at the same time
If space is limited, a combi boiler may be more suitable – but if your home can accommodate a cylinder, a system boiler offers excellent performance and reliability.
