Boilers & Heating
System Boiler Installation in Cheshire
A system boiler works alongside a separate hot water cylinder but doesn't need a cold water storage tank, since most of the heating components are built into the boiler unit itself. This makes them a strong middle ground between a combi and a traditional regular boiler, particularly suited to larger households that need stronger hot water performance than a combi typically provides.
Why system boilers suit larger households
Because hot water is stored in a cylinder rather than heated entirely on demand, a system boiler can supply multiple outlets simultaneously without the same performance drop you'd see from a combi under heavy demand. This makes it a popular choice for properties with multiple bathrooms or larger families where several people might need hot water around the same time of day.
What's involved in installation
- Installing the boiler unit itself, which houses most of the system's pumps and controls internally
- Fitting a hot water cylinder, sized appropriately for your household's demand, either vented or unvented depending on your setup and preference
- Connecting the boiler to your heating system and the cylinder, with all necessary safety and control devices fitted correctly
Vented or unvented cylinder with a system boiler
System boilers can work with either a traditional vented cylinder, fed from a loft tank, or an unvented cylinder connected directly to the mains. Going unvented gives stronger mains pressure throughout your hot water outlets and removes the need for a loft tank, though it requires G3 qualified installation, which is something not every installer can legally carry out.
Upgrading from an older regular boiler system
A lot of the system boiler installations we carry out across Cheshire are upgrades from older regular boilers, where the existing cold water tank is removed and replaced with a more modern, space-efficient unvented cylinder setup. This is a sensible upgrade for households wanting better hot water performance without going all the way to a combi.
