Heat pump vs gas boilers efficiencies
Heat Pump vs Gas Boilers- Running Costs
Historically, heat pumps were more expensive to run than gas fired boilers. But with recent changes to energy costs, electricity is now down to only around 3.5 times more expensive than gas. This means they now share similar running costs with gas fired boilers, with the most efficient heat pumps being slightly marginally cheaper to run. The below diagram shows the running costs comparison visually with electric heaters also thrown in for perspective.
