Energy Unwrapped with Mick Wall

The OG Heat Pump YouTuber | Emilie Romain

Emilie Romain was talking about heat pumps on YouTube before almost anyone in the UK knew what they were. In this episode of Energy Unwrapped, Mick sits down with the OG heat pump content creator to hear how an accidental career pivot led her to front EcoBubl's videos in full overalls, why she thinks too many people gatekeep renewables by keeping it technical, and what it's like returning to an industry that's finally caught up with her. They also get into women in the trades, the shifting public mood around heat pumps, and Emilie's new role at Midsummer Energy helping homeowners find solar. A great listen for anyone on their own renewable energy journey. 📊 Real-world UK energy data, analysis and tools: 👉 https://energy-stats.uk 🔥 Need help choosing a trusted heat pump installer? 👉 https://energy-stats.uk/trusted-heat-pump-installers/ ⚡ Switch to Octopus Energy (we both get £50): 👉 https://mickwall.octopus.energy/

The Holy Trinity – LIVE at The Heat Pump Show

This episode is a little different — recorded LIVE at The Heat Pump Show in Newark (April 2026), where I joined an expert panel discussion on what’s becoming known as:⚡ The Holy Trinity ⚡Solar PV + Battery Storage + Heat PumpHosted by Simon Roberts from Heatio, this conversation dives deep into how these technologies work together to reduce running costs, improve comfort, optimise energy usage, and reshape the future of home electrification.Joining me on the panel were:🔹 Andy Rankin — Midsummer🔹 Daniel White — MCS🔹 Sean Hogan — Aventus EcoWe discuss:Solar + battery + heat pump integrationSmart tariffs & energy optimisationRunning costs vs upfront costsHome batteries & energy storageHeat pump comfort & efficiencyConsumer educationFuture energy systemsEnergy as a serviceThe future of electrified homesA huge thank you to Midsummer for organising The Heat Pump Show and inviting me to be part of the panel.Special thanks as well to Aventus Eco and Refurb & Retrofit Magazine for kindly allowing me to use recordings from the discussion.Aventus Eco:https://aventuseco.com/https://www.youtube.com/@aventus-ecoRefurb & Retrofit Magazine:https://www.refurbandretrofit.com/https://www.youtube.com/@refurbandretrofitThe Heat Pump Show organised by Midsummer:https://midsummerwholesale.co.uk/ 📊 Real-world UK energy data, analysis and tools:👉 https://energy-stats.uk🔥 Need help choosing a trusted heat pump installer?👉 https://energy-stats.uk/trusted-heat-pump-installers/⚡ Switch to Octopus Energy (we both get £50):👉 https://mickwall.octopus.energy/

Heat Loss with Steph Willis from Spruce

In this episode of Energy Unwrapped, Mick Wall is joined by Steph Willis from Spruce to unpack one of the most misunderstood parts of heat pump design: heat loss calculations. They explore why heat loss surveys matter, how outdated ventilation assumptions have led to oversized systems, and why many homeowners may have been quoted for larger heat pumps — and more radiator upgrades — than they actually needed. Topics include: - Fabric vs ventilation heat loss - Why old guidance produced inflated heat loss figures - The real impact on heat pump sizing and system costs - Air changes, blower door tests & infiltration - Why accurate surveys matter for installers and homeowners - How better heat loss calculations could reduce disruption and improve heat pump adoption A practical and honest conversation for homeowners, installers, and anyone interested in heat pumps, retrofit, and home energy efficiency. 📊 Real-world UK energy data, analysis and tools:👉 https://energy-stats.uk🔥 Need help choosing a trusted heat pump installer?👉 https://energy-stats.uk/trusted-heat-pump-installers/⚡ Switch to Octopus Energy (we both get £50):👉 https://mickwall.octopus.energy/🎙️ Energy Unwrapped Podcast:In-depth conversations with installers, engineers and industry experts — breaking down what actually works in UK homes.Alongside the podcast, you’ll find practical guides, deep dives and real-world performance data to help you make smarter energy decisions.

Join The Living Lab | Claire Rowland

In this episode of the Energy Unwrapped Podcast, I’m joined by Claire Rowland from the Living Lab at Energy Systems Catapult. The Living Lab is a panel of over 5,000 UK households sharing real energy data, helping us understand how people actually use energy in their homes. We talk through what that data shows about EVs, solar panels, batteries and heat pumps, including which technologies people install first and how households build towards fully electrified homes. We also dig into how the data is collected, what it’s used for, and how it feeds into product development, research and even energy system planning. Claire explains how companies and policymakers use this real-world insight to design better services, tariffs and technologies. We reference this report during the episode: What can the Living Lab tell us about home energy technology adoption? https://es.catapult.org.uk/insight/what-can-the-living-lab-tell-us-about-home-energy-technology-adoption/ [https://es.catapult.org.uk/insight/what-can-the-living-lab-tell-us-about-home-energy-technology-adoption/] We also cover how you can get involved in the Living Lab, what’s involved, and what participants get back, from paid trials to early access to new technologies. If you’re interested in real-world home energy data and where UK homes are heading next, this one’s worth a listen.

Octopus Energy Heat Pumps Explained | TJ Root

In this episode of Energy Unwrapped, I’m joined by TJ Root from Octopus Energy to walk through the full journey of getting a heat pump, from the first online quote through to survey, design and installation. We talk about the Octopus Cosy heat pump, why it looks the way it does, how it is installed and what really matters when it comes to heat loss, radiator sizing and system design. There is also a good discussion around common concerns like noise, siting and R290 refrigerant. A big part of this episode is about getting the basics right. We get into why heat loss figures can vary, why gas usage is not always a reliable guide, and why slightly undersizing a heat pump can be a bigger risk than many people realise. If you are thinking about a heat pump, or just want to understand how the process actually works in a real UK home, this is a really useful one.
