What Is a System Boiler?

A system boiler uses a separate hot water cylinder to supply your taps and showers with plenty of hot water. Unlike traditional regular boilers, it doesn’t need a cold water tank in the loft. All the major components (like the pump and expansion vessel) are built into the boiler itself, making installation quicker and more efficient.

System boilers are the go-to choice for homes where hot water demand is high and multiple people may be using the system at the same time.

Is a System Boiler Right for You?

System boilers are especially popular in larger homes and properties with multiple bathrooms. They’re designed to deliver hot water quickly, reliably, and at mains pressure - meaning you can run more than one tap at once without losing heat or flow.
Benefits of a System Boiler:
  • High Hot Water Flow – Perfect for larger families or multi-bathroom properties
  • No Loft Tank Needed – Saves space and simplifies installation
  • Mains Pressure Showers – Powerful showers and fast-filling baths
  • Solar Compatible – Works with solar water heating systems
  • Fast Heat Recovery – Hot water cylinder reheats quickly between uses

Jay Jay
I'm so pleased we found Blackpool Boiler Installations! Everything about the process was so easy, the website is incredibly clear and helpful and when we made the booking we were provided with lots of helpful advice. Craig and his glamorous assistant arrived punctually and were totally friendly and professional throughout the installation of our new radiator, including balancing the heating system afterwards. They went out of their way to ensure we had the correct parts and as an added bonus, patiently entertained our very inquisitive puppy 😂
Finding reliable trades can be so frustrating so BBI were a breath of fresh air and we will definitely be using them again.

Edit: Used BBI again to fit a couple of new rads and do a power flush of the system. Engineer Jason was so helpful, friendly and polite, and really went the extra mile to help. Thanks again BBI!
Response from the owner:Thank you for your fantastic review, Jay Jay! We're thrilled to hear that you found the process easy and our website helpful. Craig and the team strive to provide a friendly and professional service, so it's great to know they met your expectations, even with your curious puppy around! We truly appreciate your trust in us and look forward to assisting you again in the future.

System Boiler FAQs

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

A combi boiler heats water instantly on demand and doesn’t require a hot water cylinder. A system boiler stores hot water in a cylinder, making it better suited to homes with higher hot water demand or multiple bathrooms.

Do I need a water tank in the loft for a system boiler?

No. System boilers take water directly from the mains and only require a hot water cylinder.

How long does it take to install a system boiler?

Most installations take 1–2 days, depending on whether you’re replacing a system boiler or converting from a different type.

How much space does a system boiler need?

You’ll need space for the boiler unit (usually kitchen/utility room) and the hot water cylinder (commonly in an airing cupboard).

Can I get a system boiler on finance?

Yes. We offer flexible boiler finance plans with no deposit required. Get in touch for a tailored quote.
