Breakdown of typical boiler components and cost. 

  • New boiler | £500 - £1,700

To replace an existing boiler which cannot be repaired, or when repair of an existing boiler would cost more than the price of a new one.

  • Heat exchanger | £300 - £650

This transfers heat from the gas in your boiler to the water circulating around the system.

  • Diverter valve | £25 - £200

This opens and closes, allowing or restricting the amount of hot water travelling through your central heating system.

  • Magnetic filter | £110 - £220

This is used to attract any bits of metal and debris floating through the pipes, preventing blockages.

  • Gas valve | £70 - £240

This controls the amount and flow of gas to the pilot light and burner in your boiler.

  • Fan | £65 - £260

The fan is used to create a draught, which is then used to push harmful gases out of the flue pipe connected to the boiler.

  • Heating pump | £100 - £200

This is the part which pumps hot water around the central heating system, via the radiators, and back to the boiler.

  • Air pressure switch | £20 - £60

The pressure switch recognises whether the fan is running, thus making sure all waste gases have been emptied from the system.

  • Flue | £40 - £50

This is the pipe which allows the waste gases and steam to flow from the boiler to outside your house.

  • Timer | £45 - £150

This allows the user to decide when your heating will come on and go off.
