What is a boiler service and how does it work?
Boilers are an important part of a central heating system. In simple terms, boilers heat water to generate heat for the home. When the system calls for heat, gas enters a sealed combustion chamber, ignition starts the heating process, and a heat exchanger transfers heat into the water that circulates through the system.
Modern boilers can run on gas, oil, or electricity and often use radiant heat to warm rooms. Key considerations include condensing vs. non-condensing design, sealed combustion, home size, climate, and efficiency rating.
