BetaTalk - The Renewable Energy and Low Carbon Heating Podcast Nathan Gambling BetaTeach

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

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.

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.

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.com


Once again, thank you for being part of something special.
