The cost for a new boiler will largely depend on what model you purchase. This is because the different types can vary in terms of complexity and the number of components.

  • CHP boiler – A new variation that merges power and heat that’s fairly simple to install
    Regular boiler – Needs a separate water tank for installation
  • Combi boiler – These are the easiest to install because they don’t require a storage tank or water cylinder
  • System boiler – You need a cylinder but the machine is equipped with all the other necessary components
