Do Heat Pumps Fail in Freezing Weather?
Is Gas Actually Cheaper?
3 Winters With a Heat Pump: What Really Happens in Sub-Zero
Do Heat Pumps Struggle in Winter?
Living With a Heat Pump: 3 Winters Later
How well does a heat pump perform in winter? In this video I test my air-source heat pump at –3°C and share real running costs, COP, noise levels, and heat output during the coldest week of the year.
See how warm the house stayed, how much it cost per day, and how it compares to a gas boiler in freezing weather. This is real-world data from three winters of heat pump use — no sales pitch, just facts.
Keywords: heat pump winter performance, heat pump freezing temperatures, heat pump cost, heat pump COP, heat pump vs gas, air source heat pump review, cold weather heat pump test.
