A system boiler works with a hot water cylinder to provide heating and hot water across larger properties. If you have more than one bathroom, or a household that uses a lot of hot water simultaneously, a system boiler is often a better choice than a combi. We install system boilers across Cardiff from all leading manufacturers and handle everything from the boiler itself to the cylinder, controls, and pipework. Call +44 7812 510121 to arrange a survey.


When You Need System Boiler Installation

A system boiler is worth considering if you have two or more bathrooms, if your current combi can’t keep up with demand, if you’re building an extension with an extra bathroom, or if you’re replacing a back boiler and existing cylinder setup. Larger Cardiff homes in Whitchurch, Rhiwbina, and Radyr often benefit from a system boiler configuration.


Our System Boiler Installation Process

We survey your property to size the boiler and cylinder correctly. On installation day we remove the old system, fit the new boiler and cylinder, connect all circuits, install controls and programmer, and commission the full system. We test hot water delivery to all outlets before we leave and register the warranty.


System Boiler Installation Cost in Cardiff

The total cost covers the boiler, cylinder, installation labour, and controls. We provide a written quote covering everything before work starts. Finance options may be available.
