System Boilers


What is a System Boiler?

boiler and solar range

A system boiler, like a conventional boiler, requires a separate water store to supply hot water. The main difference is that system boilers have the pump integrated into the boiler and have the option of an integrated motorised valve.This usually makes installation quicker and easier. System boilers are for use on pressurised systems, often with unvented cylinders making them a great choice for efficiency. They are also the number one choice to use with a twin coil solar cylinder, delivering environmental benefits as well as driving down gas bills.
