Heating a home with cold air sounds like it breaks the laws of physics. Actually, it uses them.
Air source heat pumps can be up to 5× more efficient than a gas boiler... and the secret is 200-year-old thermodynamics, not magic. Matt Lipson from Undaunted, Imperial College's clean tech innovation hub, explains exactly how they work, busts the most common myths, and introduces the next generation of heat pump technology in development.
The Royal Institution building itself is now heated by air source heat pumps — reducing carbon emissions from our Grade I-Listed building by 42%, putting us in the top 20% of non-domestic energy performance ratings in the UK.
