We met with Nathan Gambling of the Beta Teach platform and BetaTalk podcast. A champion for better heating systems, better training and education, renewables, and clean technology.We talked about the challenges and complexities associated with heating engineering, not just heat pumps, and the need to optimise our existing heating infrastructure in order to begin seriously reducing demand because we can't change everything at a stroke. We also discussed challenges and problems around training, finding good engineers, and their value, whether it's really appreciated or not.BetaTeach is his platform for heating engineers. BetaTalk is his own award-winning podcast that's well worth a listen.
