This is the second episode of the special Heat Pump Ready podcast series, in collaboration with the Carbon Trust with funding from the Department for Energy Security and Net Zero.
In this episode, Nathan talks to 4 Heat Pump Ready projects to discuss ‘How Innovation can improve the heat pump survey and design process’.
Key topics discussed include:
- Ways to improve heat loss calculations, the limitations of standard methods and the potential role of measured heat loss in heat pump surveys.
- Innovative tools to improve and streamline the survey process, potentially reducing the need for surveyors to visit properties to generate quotes and system designs
- What tools do engineers and installers need to deliver an excellent result to their customers?
A summary of the speakers and their Heat Pump Ready projects is provided below:
Thomas Whiffen – GEO
Utilising data from an existing portfolio of energy modelling and smart thermostat technologies, GEO is looking to provide a solution that will deliver an estimate of a heat pump system required for a property before a boots-on-the-ground assessment.
Hermione Crease – Purrmetrix
Working with Hoare Lea, this project will use in-home energy monitoring to calculate the heat loss of a property and provide a forecast of appropriate heat pump products that would suit the homeowner.
Richard Jack – Build test Solutions
In conjunction with Veritherm and Elmhurst, Build Test Solutions use their expertise in measured domestic energy use to determine an accurate heat loss of a property, which can then be used for accurate heat pump sizing.
Griff Thomas: Heatly
Using just your phone camera and the Heatly app, this tool will allow a homeowner to conduct a building survey themselves and receive a complete heat pump design. Supporting both installers and homeowners.

Nigel spoke in a personal capacity. I was extremely grateful he came on the show. I have been critical of Octopus in certain regards but am also well aware they are doing important work. It was a pleasure to have Nigel speak on my show.
I also chatted with Dan Kelly, Managing Director at Dartmoor Energy. Dan has nine years experience with heat pump systems as well as being a qualified PAS2035 retrofit coordinator and assessor.
For me, the episode helps illustrate that the fa bric first mantra has possibly led the UK down the wrong path. And it could be argued there has been a waste of Government funds, essentially tax payers money.
The most vehement of fabric first advocates, to me, clearly do not understand why the forefathers of thermodynamics got excited about heat pumps: things which used work to do heat rather than things which use heat to do work. The former being able to reach well above the 100 percent efficiency cap of the later.
It highlights how many are not taking ownership of their own learning and understanding what people like Lord Kelvin knew back in 1852.
It has been far too easy for people to disseminate "fabric first". Quite honestly it is often laziness and highlights a lack of professional development
It is totally understandable that consumers do not understand the science of heat but for those involved in the discourse, especially if they are being paid and funded via money from the tax payer they need to take ownership of their own learning and bring them selves up to speed.

Nathan was grateful the IMA reached out to ask if their CEO, Simon Storer, could come on the podcast to contribute to a very interesting debate.
Nigel Banks from Octopus (who wrote this fabric article) was scheduled to appear on the show and will be coming on for a follow up episode.
Nathan was very grateful Richard Erskine, who could step in at short notice to be a guest host, who has lots to offer in the debate and wrote the very good "Insulate Britain! Yes, but by how much" essay.
Great episode which will be continuedSupport the show

Nathan sat down to chat all things heat pumps and training with Clayton Brown from CB Heating.
EDF acquired CB Heating back in 2022 which is one of the largest heat pump installation entities in the UK.
EDF’s strategic investment and partnership with CB Heating have supported the development of the HPIN Academy. This academy provides free training to upskill engineers at every level in the UK.
The episode also discusses the recent partnership between Ideal Heating, a group Atlantic company, who manufacture and supply heat pumps.

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 problemSupport 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 [email protected]
Once 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
