More information
What system boiler installation covers
A system boiler is designed to work with a hot water cylinder, making it a strong option where you want good hot water flow to multiple taps. Your installation is planned around the existing pipework, controls, and cylinder setup, with clear scope agreed before work starts.
Typical inclusions:
- Assessment of the current boiler, cylinder, controls, radiators, and pipework
- Advice on correct boiler sizing and suitability for your property and hot water demand
- Safe isolation and removal of the old boiler (and associated components where required)
- Installation of the new system boiler and connection to heating and hot water services
- Upgrades to essential controls and safety components where needed
- System cleaning, inhibitor dosing, and checks for leaks and correct circulation
- Full commissioning, testing, and handover so you know how to run the system
- Completion of required certification and notifications for compliance
When a system boiler is the right fit
This service suits you if you already have a hot water cylinder, or you want stored hot water for busy periods. It is often chosen for family homes with more than one bathroom, properties where several taps may run at once, and situations where water pressure and flow rate matter.
How the installation is delivered
Work starts with confirming the existing layout, flue route, condensate drain, gas supply, and ventilation requirements. The old boiler is removed, the new boiler is fitted and connected, and the system is filled, cleaned as required, and balanced. Controls are set up, safety checks are completed, and performance is tested before handover.
After installation: performance, paperwork, and next steps
You receive a clear handover of how to use the heating and hot water controls, plus the commissioning and compliance paperwork for your records. If the system would benefit from further optimisation, you will be advised on sensible improvements like control upgrades or radiator balancing. Ongoing servicing helps keep the boiler safe, efficient, and reliable over the long term.
