In this podcast Nathan chats with his friends Barry from Renewable Heat and Matt from Matt Rigby Heating Ltd. The guests and Nathan discuss Matts journey from a gas engineer to a heat pump engineer. It mentions how Barry has provided mentorship which is a far better way to help gas engineers transition than the current system of just sending them on a powerpoint course.This season is sponsored by Ultimate Renewables Supplies Support the show
Nathan was kindly invited by the Heat Geek team to host a podcast at their Installer Show stand where he chatted to Adam Chapman, founder of Heat Geek and Karolis Petruskevicius the brains behind HomelyThe discussion involves what is currently happening in the heat pump industry as well as Homely's heat pump optimisation tool.

Yes, but by how much"...
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...
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...

All this looks really innovative. It's great to see companies focusing on more efficient and sustainable ways to handle industrial heat. This could be an exciting opportunity for people looking to invest in renewable energy technologies. For those interested in self-reliant solutions, browsing 4patriots https://4patriots.pissedconsumer.com/review.html could provide some additional products and ideas for energy efficiency. Caldera's approach could have a big impact on how industries manage energy in the future.

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?
