                     How Boiler Servicing 
Improves Energy 
Efficiency in Older 
Homes
Welcome to our presentation on optimizing energy efficiency in 
older homes through professional boiler servicing. We'll explore the 
benefits of regular maintenance and introduce GasConnect as your 
trusted partner.
Introduction: The Energy 
Efficiency Challenge in Older 
Homes
Older Boilers
Often operate at 60-70% efficiency, wasting significant energy.
Modern Boilers
Can achieve over 90% efficiency with proper care.
Boiler Servicing
Crucial for optimizing performance and reducing costs. Consider our 
boiler installation service for an upgrade.
Reduce Carbon Footprint
Maintaining efficiency directly contributes to environmental sustainability.
Understanding Boiler Servicing
Comprehensive Check Vital Part Cleaning
Engineers inspect all boiler components thoroughly. Removes debris and buildup for optimal function.
Issue Identification Safety Compliance
Detects and resolves problems before they escalate. Ensures adherence to all safety regulations.
Key Boiler Components & Efficiency

How Servicing 
Improves Efficiency: 
The Burner
Dirty Burner Causes incomplete 
combustion and fuel waste.
Servicing Ensures optimal air-fuel 
mixture, maximizing heat 
output.
Annual Savings Up to 15% on heating bills 
with a clean burner.
Soot Layer A 1mm layer can reduce 
efficiency by 5%.

Efficiency: The Heat 
Exchanger
Scale Buildup
Mineral deposits reduce heat transfer efficiency significantly.
Servicing
Professionals remove scale, maximizing heat absorption by the water.
Typical Improvement
Expect a 5-10% increase in heat transfer efficiency after cleaning.
Prevents Overheating
Regular cleaning also extends the boiler's overall lifespan.
Practical Tips for Maintaining 
Energy Efficiency
Annual Boiler Service
Schedule with a Gas Safe registered engineer for optimal performance.
Bleed Radiators
Regularly remove trapped air for efficient heat distribution.
Insulate Pipes
Minimize heat loss and reduce energy consumption.
