Combi Boilers For Smaller Homes

Combi (Combination) oil boilers offer instant hot water and heating in a single compact unit. Ideal for smaller homes, they eliminate the need for a separate hot water cylinder and provide a space-saving solution. Our team ensures proper installation and system configuration to maximise performance. We also advise on maintenance and servicing requirements to maintain efficiency and longevity, giving you peace of mind that your heating system will operate optimally throughout the year. Combi boilers are perfect for homeowners seeking convenience, instant hot water, and minimal disruption during installation.

System And Heat-Only Boilers For Larger Properties

System and heat-only boilers are designed for properties with higher hot water demands or multiple bathrooms. System boilers work with a separate cylinder to deliver reliable heating, while heat-only (regular) boilers are suited to traditional systems with both cold water and hot water storage tanks. Our engineers assess your property's requirements and recommend the most suitable option. Installation is handled professionally, ensuring compliance and efficiency. These solutions are ideal for homes requiring robust heating systems capable of supporting family-sized households with consistent hot water availability.

Flexible Internal And External Installations

We offer both internal and external boiler models to suit your property layout and space constraints. Internal models are standard floor-standing units, while external boilers come with a weatherproof casing to save indoor space. Our team provides expert guidance on which model balances efficiency, cost, and space. Installation is carried out to strict safety standards, ensuring reliable performance for years to come. For more information on maintaining your heating system, see our Power Flushing Services and Plumbing Services pages to arrange a consultation.
