Tamsin Lishman joins Bryony this week to talk heat pumps. Tamsin is CEO of Kensa Group, a Cornwall-based manufacturer and installer of ground source heat pumps. Kensa is the UK's only manufacturer of ground source heat pumps. Both air source and ground source heat pumps are rapidly growing technologies, and Tamsin believes that Kensa's heat pumps can - and will - be deployed to electrify domestic heating in the UK. On a recent episode of Cleaning Up, Fatih Birol, Executive Director of the IEA, argued that heat pumps are "the closest thing to a silver bullet" we have in the race to net-zero. In over two decades, Kensa has saved over 1 million tonnes of carbon through ground source heat pump installations. The Kensa Group is partly owned by Legal & General Capital, part of Legal & General PLC, and Octopus Energy. Tamsin was appointed CEO of Kensa Group in July 2023. Previously, she had stints at EnergyNest and Centrica. She holds a Master of Engineering from Oxford University.    Links See Kensa's website here: https://www.thekensagroup.com  Read the IEA's report on the future of heat pumps: https://www.iea.org/reports/the-future-of-heat-pumps (For UK viewers) Check out the UK government's tool to see if a heat pump could be suitable for your home: https://www.gov.uk/check-heat-pump Read this Guardian piece on heat pump installations in the UK: https://www.theguardian.com/business/2024/jan/08/greener-cheaper-much-warmer-heat-pump-owners-laud-their-new-system Read about Kensa's recent fundraise of £70m from Octopus and Legal&General, with the help of EcoPragma Capital, here: https://www.kensaheatpumps.com/news-blog/pump-it-up-octopus-energy-and-legal-general-make-britains-biggest-investment-in-ground-source-heat-pumps/
