A New Voice Meets Old Hands: BetaTalk's host Nathan, new to media, chats with his friends Joe Sharpe, Joe Dart and Andrew Gavid at Lyrical Communications

Episode Summary:

In this special episode of Trade Media Uncovered, host Nathan Gambling of the BetaTalk podcast steps into the world of long-standing trade journalism. Nathan, a new voice in the heating sector's media landscape, sits down with the pioneers who have shaped the industry's discourse for decades.

We delve into the fascinating history of trade media, from the glossy pages of published magazines to the fast-paced, digital world of today. This conversation explores how the way professionals communicate, learn, and do business has been transformed by technology. The discussion also takes a deep dive into the history of The Installer Show, the UK's largest heating and plumbing trade exhibition, and how media works alongside events and awards. We even discuss the future of AI in the industry, including the work Lorefully did with Nathan at the Installer Show.

Key Topics Covered:

• The unique role of trade media in the heating and plumbing industry, and how it has evolved from print to digital.
• A look back at the origins of trade publications, including the journey of Refrigeration News (1898) which became RAC Magazine, where our guest, Andrew, once worked before eventually joining the Installer team at Lyrical Communications.
• How the ABC Certification served as an  auditor for the circulation of print magazines.
• The pivotal shift from traditional print to digital platforms and the rise of citizen journalists and influencers.
• How media works alongside events and awards to build and sustain a community.
• We discuss the future impact of AI on the industry, and Nathan learns what the NCTJ (National Council for the Training of Journalists) is. 
• A "then and now" look at trade events, including the evolution of The Installer Show and its new counterpart, the Elemental Show.

The show also discusses the Guild of Master Heat Engineers

Join Nathan on this episode of BetaTalk as he sits down with Olly Cutting, Johann Kühns, and Pranjal Arya from HomeTree. The team from HomeTree shares their incredible journey, from a boiler installation company to a multifaceted energy services provider. We learn how Olly and Pranjal's economic backgrounds, combined with Johann's expertise in Climate Change management and finance from Imperial College London, have shaped their innovative, data-driven approach.

The Customer Journey Flywheel

The conversation centers on HomeTree's innovative business model, structured around a "customer journey flywheel" with three key divisions:

• Home Cover: Offering service plans for boilers and heat pump installations, rivaling big players like British Gas.
• Renewable Installations: Specializing in the installation of solar, battery, and heat pump systems.
• Renewable Financing: A crucial division that helps customers overcome the significant upfront cost of new energy systems, making the transition more accessible.

This flywheel model ensures that customers are supported at every stage of their energy transition.

A Different Approach to Acquisition

Nathan and his guests discuss HomeTree's unique strategy of acquiring local SME's (Small and Medium-sized Enterprises), like the respected IMS Heat Pumps Ltd led by Emma Bohan. They explore why this approach is so beneficial for both HomeTree and the acquired businesses. HomeTree's data revealed that customers prefer working with local installers, and this acquisition model allows them to scale while maintaining a personal touch.

Beyond Technology

The discussion also highlights that the move to renewable energy isn't just a technological change; it's a behavioral shift for customers. Nathan shares his thoughts on how the Guild of Master Heat Engineers can collaborate with HomeTree to help both the company and its customers navigate this transition, building on the great conversation they started over dinner. 🍽️

Episode Notes:

Welcome back to BetaTalk! In this fascinating episode, we delve deep into the world of air-to-air (A2A) heat pump systems for domestic properties. We were incredibly fortunate to be joined by two distinguished guests: Es Tresidder, a consultant specialising in Passivhaus design and low-carbon building design optimisation, and Michael Cosham, a seasoned HVAC engineer with 47 years of invaluable experience.

Our conversation began by exploring air-to-air systems in general, including Michael's personal experience building an A2A system for his first home on Canvey Island. Es then shared insights into the A2A system installed in his own highly efficient home, providing a real-world perspective on their performance.

We thoroughly discussed the numerous advantages of A2A systems in domestic properties, highlighting their efficiency and effectiveness. We also touched upon some perceived disadvantages, but as our conversation unfolded, it became clear that many of these concerns, such as fan speeds, comfort, noise, and even dry skin issues, may be simple to resolve with proper system setup and design. Indeed, with the right configuration, these issues may not even exist. 

For more on this, and avoiding potential pitfalls, Es has provided these insightful articles:

• About overheating in low-energy buildings: https://www.highlandpassive.com/do-low-energy-buildings-have-an-overheating-problem/
• Understanding thermal comfort: https://www.highlandpassive.com/why-do-i-feel-chilly/

A key takeaway from this episode was the remarkably low cost of A2A heat pumps, making them an increasingly attractive and accessible option for homeowners looking to embrace sustainable heating solutions.

Join us for a truly enlightening discussion that challenges preconceptions and sheds light on the true potential of air-to-air heat pump technology.
