Efficiency Comparison
Heat pumps typically achieve 300-400% efficiency by extracting heat from the air or ground, while gas boilers max out at around 95%.
However, the electricity cost per kWh is higher than gas, so running costs depend on your tariff and usage patterns.
Installation Considerations
Heat Pumps
Require outdoor space, may need upgraded radiators, and work best in well-insulated homes.
Gas Boilers
Compact, quick to install, but require gas connection and annual safety checks.
