In this episode, Nathan invites Mick Wall, his 'expert consumer,' back to have a discussion with the lads from Havenwise, a company dedicated to helping with quality heat pump installations. Havenwise runs an API which optimizes the weather curves on the heat pump, as well as looking at time-of-use tariffs. You can choose to use various functionalities. For example, Mick only uses the optimizer for his space heating. Nathan likes what Henri and Alex at Havenwise are trying to achieve. Take a listen...it's a very enjoyable one!

Episode Description: Host Nathan dives into the rapidly evolving world of Artificial Intelligence and its potential impact on the plumbing and heating industry. Joining him are Barrie and Amrit from Lorefuly, experts in leveraging technology for the trades.

Key Discussion Points:

• The Hallucination Hazard: The trio discusses the crucial issue of Large Language Model (LLM) "hallucinations" – where AI systems confidently present inaccurate or fabricated information. This raises serious concerns about relying solely on unverified AI content.
• RAG to the Rescue: The Power of Accurate Data: Barrie and Amrit explain the concept of Retrieval-Augmented Generation (RAG) and its importance in ensuring AI provides reliable and trustworthy information. By grounding AI responses in curated and accurate data, RAG offers a pathway to creating genuinely useful resources for professionals in the field.
• Lorefuly & BetaTeach at the Installer Show 2025: Exciting news! Lorefuly and BetaTeach will be showcasing their AI-powered solutions at the Installer Show 2025 at the NEC. Find out how they are harnessing AI to benefit plumbers and heating engineers.
• OEM Opportunities: Heating appliance manufacturers can get involved in this innovative initiative! Learn how OEMs can contribute their expertise and data to create valuable AI-driven tools for installers.
• Pre-Show Webinars: Stay informed! Nathan, Barrie, and Amrit announce upcoming webinars (first one here: https://tinyurl.com/BetaTalk-AI designed to provide more details on how OEMs can participate and the benefits of getting involved.

Mentioned:

• Artificial Intelligence (AI)
• Large Language Models (LLMs)
• Hallucination (in AI)
• Retrieval-Augmented Generation (RAG)

Nathan speaks with Leah Robson, owner of a small SME (Your Energy Your Way) installing heat pumps, batteries, and solar, about her recent appearance at Westminster. Leah gave evidence to the "Workforce Planning to Deliver Clean, Secure Energy" Committee, invited through Ellora Coupe of "Her Retrofit Space." The discussion centres on whether Leah's concerns about workforce training, particularly for heat pump installation, were understood by the committee.

Key Discussion Points:

• Westminster Testimony: Leah shares her experience presenting to the committee and her assessment of whether her points regarding the challenges faced by small businesses were acknowledged.
• The Three-Day Training Issue: The core of the episode focuses on the prevalence of three-day heat pump installation courses and Leah's concerns about their adequacy. She highlights potential issues with the depth of knowledge gained and the practical experience of some trainers.
• Heating Training Grant (HTG): Who Wins? Nathan and Leah explore the effectiveness of the HTG, questioning whether the primary beneficiaries are the awarding bodies, training centers, or the engineers themselves.
• Engineer Perspectives: Feedback from experienced gas engineers who have taken these short courses suggests the training is insufficient and doesn't adequately prepare them for real-world heat pump installations.
• Taxpayer Value: The episode raises concerns about the value for money for UK taxpayers funding the HTG if the resulting training isn't producing competent installers.

In this insightful episode, host Nathan sits down with two key figures from the Heat Pump Association (HPA) – CEO Charlotte Lea and Chair Craig Dolan – to explore the role the HPA plays in the evolving UK heating landscape. They delve into the value the association brings to the industry, particularly as the nation transitions towards low-carbon heating solutions.

The conversation tackles the fundamental question of whether industry associations are still necessary in today's rapidly changing world. Charlotte and Craig passionately argue for their continued relevance, highlighting their crucial function in providing a unified voice for the heat pump sector and driving positive change.

A potentially contentious area is explored as Nathan raises the issue of potential conflicts of interest arising from HPA membership that may include companies also affiliated with the boiler industry and their strong advocacy for hydrogen boilers through the Heating and Hot water Council (HHIC). This leads to a nuanced discussion about navigating diverse interests within the broader heating industry.

Nathan expresses his support for the HPA's proactive new strategy focused on amplifying the voices of heat pump installers – the boots on the ground who are essential to the successful rollout of this technology.

The guests showcase the tangible benefits of HPA membership by highlighting the development and release of valuable industry resources, such as the new Residual Current Device (RCD) guidance and comprehensive heat pump system commissioning documents.

The conversation then shifts to the complexities of the UK heating controls industry. Nathan and his guests discuss whether the competitive nature of the market might inadvertently hinder the adoption of common engineering sense and best practices in the design of energy-efficient heating systems.

Finally, Charlotte and Craig shed light on the significant policy work undertaken by the HPA, including their collaborative efforts with the Department for Energy Security and Net Zero (DESNZ). They explain how the association actively engages with policymakers to shape regulations and support the widespread adoption of heat pump technology in the UK.

Key Discussion Points:

• The core value proposition of the Heat Pump Association in the UK heating industry.
• The ongoing relevance and necessity of industry associations in the current climate.
• Navigating potential conflicts of interest with members also involved in the boiler/hydrogen fuel debate via the HHIC.
• The HPA's new focus on empowering and promoting the voice of heat pump installers.
• The importance and impact of HPA-produced technical documents, such as the new RCD guidance and commissioning documents.
• The challenges and opportunities within the UK heating controls industry and the potential impact of competition on best practices.
• The HPA's crucial policy work and collaboration with the Energy department.
