Can you really warm your house using freezing outdoor air?
In short: It sounds impossible, but air source heat pumps use established thermodynamic principles to extract heat from cold environments. Matt Lipson explores how this technology functions, addresses common misconceptions, and highlights future innovations in heating efficiency.
While it seems counterintuitive, air source heat pumps operate on 200-year-old thermodynamic concepts rather than magic. These systems can achieve up to five times the efficiency of a traditional gas boiler, providing a cleaner alternative for space heating.
The Royal Institution has implemented this technology in its own Grade I-listed facility. By switching to heat pumps, the building cut its carbon emissions by 42%. This upgrade moved the historic site into the top fifth of energy-rated non-domestic buildings across the United Kingdom.
