A traditional setup now mostly phased out
A boiler is fitted behind a gas fireplace
Heats water for central heating and domestic use
Common in UK homes from the 1960s1990s
Example Baxi Bermuda

2 GasFired Combi Boiler

More modern and efficient
Provides instant hot water and heating without a tank
Usually wallmounted and separate from a fire

3 HighEfficiency Condensing Boilers

Burns gas to heat water but uses waste heat for greater efficiency
Can be used with radiators or underfloor heating



How It Works Back Boiler Style

Gas fire heats a heat exchanger behind it
Heat is transferred to water in a sealed unit
Heated water is pumped through radiators andor to hot taps



Pros

Spacesaving for older homes
Can be costeffective in smaller properties
Combined heating and hot water in one unit



Cons

Old models are inefficient compared to modern condensing boilers
Many are noncompliant with modern regulations
Can be costly to repair or replace
Fire and boiler combo means more wear and tear
