System Boilers
City Plumbing offers installers a wide range of gas system boilers from trusted brands, along with service options such as free delivery and Click & Collect. A gas system boiler is an efficient heating solution for homes with high hot water demand, providing a steady flow by heating water stored in a cylinder. It is energy-efficient and saves space by removing the need for loft tanks.
What Is a Gas System Boiler?
A gas system boiler is a modern, efficient heating unit that takes water directly from the mains supply to feed the central heating system (radiators) and to heat and store hot water in a separate storage cylinder, typically located in an airing cupboard.
Unlike older regular boilers, a system boiler has essential components like the pump and expansion vessel built in, eliminating the need for a cold water tank in the loft, which makes it a space-saving solution.
By drawing water directly from the high-pressure mains, it delivers a strong, consistent flow of hot water to multiple outlets simultaneously, making it an ideal and cost-effective choice for larger homes with multiple bathrooms and high simultaneous hot water demands.
Why Choose a System Boiler?
A system boiler is an excellent choice because it provides a steady, high-pressure hot water supply to multiple taps and showers simultaneously, making it perfectly suited for homes of all sizes.
Since many components, such as the pump and expansion vessel, are built-in, installation is generally faster, and the system requires less external plumbing, often leading to reduced maintenance over time compared to older conventional setups.
Furthermore, system boilers are compatible with modern smart controls and thermostats, enabling homeowners to easily optimise their heating schedules and efficiency.
What Are the Key Benefits of Buying a System Boiler?
Choosing a system boiler provides homeowners with confidence due to the availability of guarantees ranging from 1 to 10 years, backed by trusted brands with a proven track record of reliability in the heating industry.
These units are specifically designed for long-term performance and require low maintenance, thanks to their many built-in components, ensuring a durable and hassle-free solution for your home's central heating and hot water needs.
System Boilers Installation FAQs
Combi vs. System (Which is better?):
System boilers are generally better suited for large homes with multiple bathrooms, as they provide a strong, steady supply of hot water to multiple outlets simultaneously.
Combi boilers are best suited for smaller homes with lower hot water demands, as they save space by not requiring a separate hot water cylinder.
Do system boilers need a cylinder?
Yes. System boilers need a separate hot water storage cylinder, but not a loft cold water tank.
Are system boilers expensive to run?
No, they are efficient. Modern system boilers are condensing models with high efficiency. Running costs depend on usage and insulation, but are cost-effective for high hot water demands.
Do I need a hot water tank with a system boiler?
Yes. A separate hot water cylinder is necessary for a system boiler, as it stores hot water for taps and showers.
Can a system boiler heat both water and radiators simultaneously?
Yes. The system heats radiators while allowing hot water to be drawn from the storage cylinder, maintaining pressure and flow.
How long do system boilers last?
A well-maintained, high-quality system boiler lasts 10 to 15 years.
