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 consequence...
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 engine...

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. Su...
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 sta...

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 cust...
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 ...
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 bo...

Nathan, I've enjoyed listening to your podcasts for a long time now but find you are drifting more and more into high level discussions which are frankly quite boring. For me and I imagine many listeners want to hear about the latest and popular products in the current UK heat pump market and feedback from home users and details about the systems installed. For example hearing about how home users have retrofitted heat pumps, costs and products used. For now I am unsubscribing from your podcast as I can't endure another boring episode Mike

I am a consumer looking for the best way to stop using fossil fuels in my home. I have done a lot in terms of insulation and looking at how best to get rid of my gas boiler, hence I dip into this podcast. I'm afraid every time I listen it just convinces me more this is not for me. And this particular edition sounds like a complete waste of public money promoting what is only ever going to be a small niche. Sorry!

You should listen to the majority of your customers, heat pumps simply won't work in the homes we live in.

Nathan, Great episode with Richard. Enjoyed all the info on modulating gas boiler heating with examples of from manufacturers, e.g. Alpha and Intergas. Please bring him back again to do one on domestic air sourced heat pumps with similar examples and manufacturer recommendations and things to look out for, e.g. best side of house to place heat pump, noise issues with neighbours, retrofit to micro bore systems, etc Mike

I'm a homeowner who is very sceptical about having a heat pump and this podcast is only reinforcing that. I could afford it but the amount of change and the lack of experienced competent engineers puts it way down my list. Renewable energy and an electric combi boiler sounds much better.

Thank you for this, you've done a great job in convincing me that the last thing I will consider is a heat pump. Too complex, have to change radiators and find space for a hot water cylinder again. An electric combi boiler combined with vehicle to grid / home technology and off peak tariffs will do it for me, my insulation is good and none of the other high costs and complexity.

A very useful podcast! I think people need to know more about renewable energy because it is our future. U.S. consumption of renewables is expected to grow over the next 30 years at an average annual rate of 1.8 percent, higher than the overall growth rate in energy consumption (0.2 percent per year) under a business-as-usual scenario. These are very good predictions, and I hope they will come true. But I'm wondering if more software will be created to simplify the workflow. For example, I heard that this software is now widely used - https://fluix.io/industry-renewable-energy . But will only it be enough, or will it be necessary to come up with something else?
