What is a system boiler?

A system boiler is a compact, self-contained unit that heats your radiators and hot water. They’re quick and easy to install and also save valuable space in your home. Our system boilers are all A-rated Worcester Bosch Greenstar models and come with a five-year manufacturer’s guarantee, which can be extended to up to ten years.

How does a system boiler work?

Unlike an ‘on demand’ combi boiler, these boilers heat water and store it in a hot water cylinder which can be installed in a convenient location, like your airing cupboard.

Is a system boiler right for your home?

This type of system is good for homes with two or more bathrooms as it provides a constant supply of hot water to any number of taps or showers at the same time. It’s also a great choice if you’re thinking of converting your loft space, as there’s no need for an expansion tank in the attic.
