Understanding heat pump running costs helps you budget effectively and compare savings against traditional heating systems. [Get Free Assessment](/free-quote)[0333 577 7010](tel:03335777010) ## Heat Pump Hourly Running Costs Explained The cost to run a heat pump per hour depends on several factors including the size of your heat pump, current electricity prices, and the efficiency (COP) of your system. Here's what you can typically expect: ### Small System 13-18p per hour (5kW system) ### Medium System 18-24p per hour (8kW system) ### Large System 24-32p per hour (12kW system) ### How to Calculate Your Hourly Cost **Formula:** Hourly Cost = (Heat Pump Output ÷ COP) × Electricity Rate **Example:** An 8kW heat pump with a COP of 3.5 running on electricity at 24p/kWh: (8kW ÷ 3.5) × £0.24 = £0.55 per hour of full output Note: Heat pumps don't run at full capacity all the time. Most modulate their output based on heating demand. ## Comparing Heat Pump Costs to Gas Boilers Despite electricity costing more per kWh than gas, heat pumps are often cheaper to run because they're 3-4 times more efficient: - **Gas boiler:** To produce 8kWh of heat costs ~40p (at 8p/kWh gas, 90% efficiency) - **Heat pump:** To produce 8kWh of heat costs ~55p (at 24p/kWh electricity, COP 3.5) - **With solar panels:** Running costs can drop by 50-70% when using self-generated electricity ## Related Guides & Resources [ ### Heat Pump Systems Samsung & Vaillant air source heat pump installation. ](/heat-pumps)[ ### BUS Grant (£7,500) How to claim your Boiler Upgrade Scheme grant. ](/boiler-upgrade-scheme-bus)[ ### How Heat Pumps Work Understand the technology behind air source heat pumps. ](/ashp/how-do-heat-pumps-work)[ ### Radiators for Heat Pumps Sizing guide, upgrade costs, and radiator compatibility. ](/ashp/radiators-for-heat-pumps)[ ### Heat Pump Costs Full pricing guide for heat pump installation. ](/ashp/how-much-does-a-heat-pump-cost)[ ### Are Heat Pumps Worth It?
