Boiler packs offer a practical, time-saving solution for heating installations, combining a boiler with essential accessories such as flues, filters, controls, or fittings in one convenient bundle. Whether you're managing a straightforward replacement or a full system upgrade, boiler packs help streamline specification, ordering, and installation.
At City Plumbing, boiler packs are designed to support both installers and homeowners by simplifying product selection while ensuring compatibility between key components.

Why Choose a Boiler Pack?

Simplified Installation -

Pre-configured boiler packages ensure compatibility between the boiler and key components, helping to reduce installation time and minimise the risk of missing parts.

Improved Project Efficiency -

By consolidating multiple items into a single purchase, installers can reduce ordering complexity and streamline logistics, particularly on time-sensitive jobs.

Cost-Effective Bundling -

Buying products as part of a pack can offer better overall value compared to sourcing items individually, helping to manage project budgets more effectively.

Consistent Specification -

Boiler packs remove uncertainty when selecting components, ensuring systems are built with compatible and manufacturer-aligned parts.

Combi Boiler Packs

Combi (combination) boiler packs provide both central heating and hot water from a single unit, without the need for a separate cylinder or tank.
  • Ideal for flats, smaller homes, and properties with limited space 
  • Hot water delivered on demand 
  • Fewer components required, making installation quicker 
Combi packs are often the preferred option for straightforward replacements or where space-saving is a priority.

System Boiler Packs

System boiler packs work with a separate hot water cylinder but include many internal components within the boiler itself.
  • Suitable for medium to large homes 
  • Designed for properties with multiple bathrooms 
  • Capable of supplying hot water to several outlets simultaneously 
These packs offer a balance between performance and installation efficiency, particularly where higher hot water demand is expected.

Heat Only (Regular) Boiler Packs

Heat only, or regular boiler packs, are designed for traditional heating systems that include both a hot water cylinder and a cold-water storage tank.
  • Best suited to older properties with existing systems 
  • Ideal for high water demand applications 
  • Compatible with low mains pressure areas 
These packs are often used for like-for-like replacements where retaining the existing system layout is preferred.

Choosing the right package

Selecting the correct boiler pack depends on several key factors related to the property and system requirements.

Property Size and Layout -

Smaller homes with one bathroom typically suit combi boiler packs, while larger properties with multiple bathrooms may require a system or heat only setup.

Hot Water Demand -

High demand properties benefit from stored hot water systems, whereas lower demand homes can rely on combi boilers for on-demand supply.

Existing System Configuration -

Replacing like-for-like can reduce installation complexity and cost. However, upgrading system type may improve efficiency or performance depending on the property.

Energy Efficiency Considerations -

Modern condensing boilers are designed to maximise efficiency and meet current Building Regulations. Selecting an appropriately sized and specified pack helps optimise running costs.

Budget and Installation Constraints -

Boiler packs can help control upfront costs, but it’s important to consider installation requirements such as pipework changes, flue positioning, and available space.
