Ground source heat pumps are among the most reliable heating systems during winter months. [Get Free Assessment](/free-quote)[0333 577 7010](tel:03335777010) ## How GSHPs Perform in Winter Yes, ground source heat pumps work excellently in winter—in fact, this is their key advantage over air source heat pumps. The ground temperature remains relatively constant throughout the year. ### Above Ground \-10°C to +30°C UK temperature variation ### Underground (1-2m) 10-12°C Stable year-round ### Winter Performance Advantages - **Consistent efficiency:** COP remains at 4.0-4.5 regardless of outside temperature - **No defrost cycles:** Unlike air source, no energy wasted defrosting - **Reliable heat output:** Full heating capacity available even at -15°C - **Lower running costs:** Better winter efficiency means lower bills when you need heat most ## Comparing Winter Performance ### GSHP vs ASHP at -5°C **Ground Source:** COP 4.0-4.5 (no change) **Air Source:** COP 2.5-3.0 (reduced efficiency) Ground source can be 30-50% more efficient than air source in very cold weather. ## 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?
