What Is a Back Boiler?

Back boilers are heating systems installed behind gas fires in fireplaces. While once common, they are now:

  • Inefficient: Typically only 60-70% efficient
  • Outdated: No longer manufactured
  • Expensive to Run: Higher fuel bills than modern boilers
  • Difficult to Service: Parts increasingly unavailable
  • Space-Consuming: Take up valuable living space
