How Boilers Work

Boilers are essential for providing heating and hot water in homes and businesses. The basic operation involves:

  1. Fuel combustion: Gas, oil, or LPG is burned to produce heat.
  2. Heat Exchange: The heat from combustion is transferred to water in heat exchanger.
  3. Circulation: The heated water is circulated through radiators or underfloor heating to warm your space and provide hot water.

This efficient process ensures your property remains warm and comfortable, especially during the colder months.
