System Boilers Prices

System boilers prices vary between £600 to £1000 with the cost of installation

System boilers are very  energy efficient as they are a sealed system. They work on the principle of stored hot water, yet many of the major components of a heating and hot water system are built into the boiler itself, thus eliminating the need for a feed and expansion cistern or, if the hot water system is pressurised, a cold water tank. The integrated components of a system boiler means that ongoing maintenance costs are usually lower than combi boilers, but they do take up more space. What is a System Boiler?


  • Loft space is not required for a hot water tank
  • High water pressure
  • Easy to install
  • Ideal for large homes with 2 or more bathrooms
  • Compact boiler dimensions


  • Installation, repair and maintenance costs can be more expensive
