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.

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. Join Ken and me as we unravel the mysteries and potential of weather compensated heating!

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.
