BetaTalk - The Renewable Energy and Low Carbon Heating Podcast

Heat pumps move energy from and energy source e.g. air, ground water (hence they are called :air source, ground source) to a sink.The sink is the emitter system within a home e.g. radiators, underfloor heating (UFH) and fan coils. Engineers, Installers, designers and the occupants of a home rely on radiators having accurate power output data. Unfortuanlty, it looks like their is a big problem in the radiator industry: the published power outputs are being over stated.This has huge consequences for heat pump systems which rely on designers designing a heat pump system which can operate at the lowest possible design temperature. Higher flow temperature to radiators requires the heat pump's compressor to work harder an use more electricity, resulting in more demand on the grid and higher fuel bills for the customer.Rob Nezard from UK Radiators has spotted a problem across the whole of the radiator supply chain and created a video to prove this. Nathan went to visit Rob (watch on youtube) to discuss the problem Support the show

In this episode Nathan chats to Paul Eastwood, Head of Energy Systems Planning at OFGEM and the past Senior Climate and Energy Advisor at the Foreign, Commonwealth and Development Office. Also joining the heat pump conversation is engineer Barry Sharpe from Renewable Heat  The discussion focuses on what an ideal customer journey is. Paul has had a heat pump system after Nathan recommended Barry to him. The episode questions if Paul's experience could have been better with the hope engineers may gain some useful insight. Topics covered are:Heat loss assessments and independent assessments.Securing quotes for heat pump installationsInstall optionsHeat pump controls and operationsHeat pump servicingWhy do heat pump installs cost more than boiler installationsThis was one of Nathan's favourite recordings and he would like to note that Paul is speaking in a personal capacity and not on behalf of any employer. Please enjoy the episode.Support the show

Sweden have had a long tradition with heating technologies and have incredible expertise regarding heat pumps. Nathan talks to the Swedish company AIRA, the new entrant to the UK's heating and home renewables industry. AIRA will be installing heat pump and other technologies across Europe bringing their expertise first to Italy, Germany and the UK.It's a great episode and Nathan enjoyed his conversation with Daniel Sarefjord, the chief executive of Aira in the UK, immensely. Support the show

As the title states, you are a very special group of people to me. You listen to me ramble on about heating for a start and I am very grateful for that.. So, thank you. I appreciate that very much.This is the first episode of 2024 and I wanted to do something a bit special. Something for you. As you know, this podcast is called BetaTALK... and the talk aspect is very important. In order to help accelerate the mainstream adoption of transitional heating technologies we first need people to start talking about them. We need to get people talking about heating in a positive and fun way. So how do we do that?This is something I care about and I know this is something you care about too. You care about getting people to talk about heating. But it's challenging. So, to help you,  Lawrence and I have developed a tool. It's a practical tool and it will  engender conversations around heating.It's new, it's fun, and it's very quirky. Take a listen and meet my partner Lawrence... together we have started up Jouln  As well as home owner listeners if you are associated with Local Authorities, Social Housing Groups, construction companies and even energy suppliers and interested in Digital Twins /artificial intelligence and how  they can help you then please contact us at lawrence@jouln.comOnce again, thank you for being part of something special.Support the show

Here is the link to the heat pump installer survey (lot's of prizes to be won)In this episode Nathan speaks with Glyn Hudson and Trystan Lea who along with open source enthusiasts have created open energy monitor and heat pump monitor.Heat pump installers and consumers are installing monitoring equipment such as heat meters onto their heat pump systems to obtain COP readings. COP stands for the coefficient of performance.The monitoring has provided the oppotunity for engineers and home owners to learn from each other about what works what doesn't work. Arguably, other monitoring schemes (which cost the tax payer money) have caused a headache to the energy transition movement because such studies were using incompetent installation companies to put these heating systems in. This has meant a low COP average which the fossil fuel industry loves to allude to.  These schemes have not shed much, if any, data on system design so no one has really learned anything from them. Conversely, this platform has engendered a hive of learning with engineers not only being able to learn from each other but also being able to validate their competence to prospective customers.  It's a great episode...take a listenSupport the show

Nathan speaks with Sandra Trittin, co-founder of tiko Energy Solutions and co-host of the podcast Talking New Energy from LCP Delta. Joining Sandra is Talking New Energy's other host Jon Slow partner at LCP Delta.The discussion centres around how we may be able to heat pumps, batteries and EVs as as virtual power plants to increase the  flexibility of the grid .Take a listenSupport the show

Econic is a new venture from Nathan's friend Christophe Grossbaier. Its aim is to make the transition from gas boilers to heat pumps smoother for both customers and installers and uses a hybrid heat pump business model to achieve this. With an engineering background and Masters from Cambridge University, Christophe appreciates heat pumps can heat almost any building but understands customers still have their concerns and worries. This business model is designed to take away the anxiety a customer may have and at the same time offer them a cheaper alternative - both in upfront and running costs.Econic will be working with local community groups as well as Local Authorities.

Nathan dives into the history of heating systems and looks at why chemical inhibitors were introduced to prevent corrosion.He also points out that manufactures are possibly misinterpreting the building regulations e.g. they are getting confused with a requirement within the building regs  and the guidance contained in an approved document.It also takes a look at the Benchmark system and questions if it is fit for purpose. Is it biased towards maintaining growth of the chemical inhibitor companies?The episode also looks at how a 1960s home could be heated from single panel radiators with just a flow of approx. 53°C... Support the show

In this episode Nathan interviews Faye Wade, his favourite academic researching the heating industry. This is because Faye understands that the most vital component of the industry is the engineer and that we need to really listen to them.Joining Faye are Nathan's friends Leah, Sovay and Rhiannon who are all involved in installing and maintaining heating systems.This is a fab episode with lot's of discussion around the transition to heat pumps and things like certification bodies, awarding bodies and MCS etc etcSupport the show

*Update: in this episode Damon and host Nathan realised after editing there was a mistake. An easy one to make as engineers like Damon have so many numbers running around in their head. He mentions he sizes radiators to 50°C when in fact Damon is one of the engineers who designs to a lower flow temp of 40-45*C for a radiator heating circuit.In this episode we speak to the fabulous engineers Damon from Blakemore Plumbing and Heating and Barry from Renewable Heat about quotations. It's a hot topic so sit back and enjoy.We also discuss the Glowmarkt website being developed by consortium partners within the Heat Pump Ready programme which Nathan, the host of the show, is part of. Support the show

I really enjoyed this episode chatting with Andrew Middleton, Managing Director at British Gas Zero and Steve Petrie, regional manager at British Gas Zero who also is a former British Gas engineer. I brought along for the ride my friend Adam Gilhespy from Carno to help me host the conversation as he also is a former British Gas engineer and like Andrew  understands strategy and processes. For anyone who knows my podcast I started it so on the ground engineers could have a more amplified voice. Unfortunately, in the energy discourses I'm privileged to be a part of these days the coal face engineers are not always being listened too.It is why it was refreshing when Andrew reached out and asked if he could come chat with us on the podcast. Andrew is one of my listeners and openly admits he has found it extremely useful to listen and learn from the engineers I have had on the show. Enjoy the showSupport the show
