What Is a System Boiler?
A system boiler works with a hot water cylinder to store hot water, while most components (like the pump and expansion vessel) are built into the boiler itself.
System boilers are ideal for:
- Homes with multiple bathrooms
- Properties where hot water is used at the same time
- Families needing strong, consistent hot water flow
- Replacing older system or conventional boilers with minimal disruption

System Boiler FAQs
Is a system boiler better than a combi?
System boilers are better for homes with multiple bathrooms or high hot water demand. Combi boilers suit smaller homes. We’ll recommend the best option for your setup.
How long does a system boiler installation take?
Most replacements take 1–2 days. Conversions can take longer depending on pipework and cylinder changes.
Do I need a hot water cylinder with a system boiler?
Yes — system boilers work with a cylinder to store hot water.
How often should a system boiler be serviced?
Once a year to maintain safety, efficiency, and warranty cover.
Do new system boilers come with a warranty?
Yes — we offer up to 12-year warranties on eligible Worcester Bosch and Vaillant boilers.
