Send us a text 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.

Send us a text Welcome back to BetaTalk, the podcast dedicated to exploring the exciting world of renewable heating! In this episode, host Nathan is joined by two fantastic guests: Barry Sharp from Renewable Heat and a familiar voice to BetaTalk listeners, and Scott Sanford who has recently embarked on his own renewable heating journey. Our conversation kicks off with a fascinating deep dive into Scott's personal experience installing a Viessmann heat pump system in his own home. We hear firsthand about his installation journey, the challenges and triumphs he faced, and the benefits he's now experiencing. This very installation was also recently featured in the SNIPEF magazine, offering a real-world perspective on adopting heat pump technology. The episode then continues with a theme that Nathan and Barry have explored in previous episodes: the crucial role of mentorship within the heating industry. We delve into Scott's heating career, his motivations for embracing renewable technologies, and his active involvement within SNIPEF. We discuss how mentorship has potentially played a part in his journey and the importance of knowledge sharing within the sector as we transition towards a greener future.

Send us a text Welcome back to the show! In this episode, I'm joined by a good friend and expert in the renewable energy sector, Ken Bone from Ultimate Renewables Supplies. Ken and I dive deep into a topic that's crucial for efficient heating and the future of low-carbon homes: weather compensated heating systems. One of the key points we explore is the apparent lack of understanding within the installer base regarding weather compensation. It's surprising, considering that condensing boilers – mandated way back in 2005 – operate much more efficiently when paired with this intelligent control strategy. But is it fair to point the finger solely at installers? We discuss why it's arguably not their fault. Ken and I explore the possibility that industry associations haven't adequately championed and educated on the benefits of weather compensation. This lack of widespread promotion has left many installers unfamiliar with its implementation and advantages. Our conversation then shifts to the burgeoning heat pump market. Are heat pump manufacturers doing enough to provide user-friendly and effective controls, both for the installer during setup and for the homeowner in their daily use? We examine the current landscape and consider areas for improvement. I also share a bit about the history of the control industry, where the ideal scenario pushed by control manufacturers for many has been individual room-by-room control. However, as Ken astutely points out, this level of granular control is often unnecessary and can overcomplicate things. We also touch on a fascinating aspect of the UK heating market: the observation that certain manufacturers are utilizing the same Chinese OEM (Original Equipment Manufacturer) for their products. This raises questions about differentiation and the potential for shared underlying technology. A central theme of our discussion revolves around whether these OEMs could produce better weather compensation controls that also incorporate room influence. Can we achieve the best of both worlds – the efficiency of weather compensation fine-tuned by individual room temperature feedback? Towards the end of the episode, we briefly touch upon the important topics of grid flexibility and demand-side response. We discuss how a better understanding and wider adoption of weather compensation by installers could significantly ease the transition to heat pumps and contribute to a more flexible and efficient energy system. This episode is a must-listen for anyone involved in the heating industry, from installers and manufacturers to homeowners interested in optimising their heating systems and understanding the future of home comfort.

Send us a text In this eye-opening episode, we delve into the contrasting approaches to water treatment in European domestic heating systems for corrosion prevention. While the UK predominantly champions chemical inhibitor solutions under the EN BS 7593 standard, many European nations embrace a wider range of methods. Surprisingly, some UK chemical inhibitor manufacturers who exclusively promote their products domestically readily offer non-chemical alternatives on the continent. Host Nathan interviews Ricky Prescott from Thoroughflush, who sheds light on the shortcomings of the BS 7593 standard. Ricky argues that manufacturers of chemical inhibitors often fail to provide sufficient information to accurately test heating systems and determine if adequate inhibitor levels are present. Adding to the complexity, while some of the UK's leading heating engineers favor the German VDI 2035 standard, the chemical water treatment group within the Heating and Hot Water Industry Council (HHIC) appears resistant to discussing or acknowledging these alternative European approaches.

Send us a text Nathan talks with Katrina from Energy Systems Catapult and Trysten Lee from Open Energy Monitor about a key question surrounding the Electrification of Heat (EoH) trial: why did the heat pumps perform so poorly? The trial, involving aprox. 740 heat pumps, showed an average Seasonal Performance Factor (SPF) of just 2.81 for air source. This contrasts sharply with the performance of heat pumps monitored by Trysten at HeatPumpMonitor.org (HPM). Interestingly, many of the installers whose systems are tracked on HPM are relatively new to the field, some with only a few years of heat pump experience. Yet, they consistently achieve high-performing heat pump installations, a stark difference from the results of the large-scale trials. This success likely stems from their adherence to the two BetaTeach principles, their approach to self-directed learning, and their use of peer-to-peer learning. They also tend to pursue different training paths, rather than relying solely on the standard 3-day BPEC and LCL Award courses. The trial, conducted in partnership with Warmworks, OVO, and E-ON, involved 19 MCS contractors installing approximately 750 free heat pump systems. Beyond heat pump performance, the trial has provided valuable insights that are informing policy development in areas such as planning permission and Distribution Network Operator (DNO) applications. Trystan and his team have managed to visualise the data captured from the trial at eoh.heatpumpmonitor.org This season is sponsored by PrimaryPro Primary Pro, a pipe insulation system developed by Dave Smith, is gaining popularity among engineers for use in heat pump installations.
