System boilers explained: What is a system boiler?

System boilers heat water and store it in a hot water cylinder, so there’s enough hot water for when multiple taps and showers are used at the same time. The cylinder is often installed in a convenient location like your airing cupboard. Our Worcester Bosch system boilers are usually installed in homes with more than one bathroom and higher water demand.
