Worcester system boilers

Just like conventional boilers, system boilers work on the principle of stored hot water. However, system boilers are different from conventional boilers in that the individual components are built directly into the boiler so that the installation is quicker and less costly. In addition, system boilers do not necessarily need a water storage tank, which makes them a great choice for homes where space comes ata premium.
