Heat Pumps Are Not New | Nathan Gambling | Betatalk
Heat pumps get talked about like they're brand new technology — they're not. On this episode of the Energy Unwrapped Podcast, I sit down with Nathan Gambling, lecturer in plumbing and heating and host of the Beta Talk podcast, to trace how Britain actually got its heating: from single-room fires, through town gas and the conversion to natural gas, to the combi boiler boom — and how heat pumps have quietly been running in the background the whole time, including one that heated a Norwich building from the River Wensum from 1945 until the 2000s.We get into:- Why "heat pumps are not new" — Graeme Haldane's 1927 experiments and John Sumner's 1945 Norwich heat pump- How Britain's town-gas-to-natural-gas conversion became one of the biggest planned engineering operations in peacetime history- Why Canvey Island became the UK's first LNG terminal- Why radiators were never designed to be scorching hot — and why that still trips people up with heat pumps today- Why the UK became the world's biggest gas boiler market, and what that legacy means for the heat pump transition now#HeatPumps #EnergyUnwrapped #UKHeating #RenewableEnergy #HeatingEngineerI'll leave a link to my trusted heat pump installer directory and the Energy Unwrapped podcast below.📊 Real-world UK energy data, analysis and tools:👉 https://energy-stats.uk🔥 Need help choosing a trusted heat pump installer?👉 https://trustedheatpumpinstallers.co.uk/⚡ Switch to Octopus Energy (we both get £50):👉 https://mickwall.octopus.energy/🎙️ Energy Unwrapped Podcast:👉 https://energy-stats.uk/energy-unwrapped-podcast/

Mixergy's Pete Armstrong: How Hot Water Cylinders Solve Grid Curtailment
Hot water cylinders are one of the UK's biggest untapped energy storage assets — and most homes don't even know it. In this episode of the Energy Unwrapped Podcast, I sit down with Pete Armstrong, CEO and co-founder of Mixergy, to unpack a decade of engineering behind the smart hot water cylinder.We get into how top-down heating and stratification let a single 200L tank store roughly 10 kWh of usable energy, why there's something like 10 times more energy sitting in the UK's hot water tanks than in Dinorwig's pumped hydro plant, and how curtailed wind power in Scotland could be turned into free hot water for half of Scottish homes instead of being switched off.Pete also walks through why Mixergy moved to local, cloud-independent control, what the upcoming Secure Smart Electricity System regulation means for appliances like this, and where hot water storage sits against home batteries and EVs in the flexibility conversation.#Mixergy #HotWaterCylinder #EnergyStorage #UKEnergy #GridFlexibility #EnergyUnwrapped🎙️ Full Energy Unwrapped Podcast:👉 https://energy-stats.uk/energy-unwrapped-podcast/📊 Real-world UK energy data, analysis and tools:👉 https://energy-stats.uk🔥 Need help choosing a trusted heat pump installer?👉 https://www.trustedheatpumpinstallers.co.uk/⚡ Switch to Octopus Energy (we both get £50):👉 https://mickwall.octopus.energy/ ⚡ Axle Energy Flexibility Referral (we both get £25):👉 https://vpp.axle.energy/landing/grid?ref=R-ZWPYRZOD Golden Rules (best heat pump hot water settings:👉 https://www.youtube.com/watch?v=YTE1NiWCOtk Future Homes Standard with Nigel Banks of Octopus👉 https://www.youtube.com/watch?v=ln_ZEHDEiJI The Cheapest Electricity has Moved👉 https://www.youtube.com/watch?v=PodKKVa_BCk

Open Energy Monitor: The Tools Changing UK Energy
In this episode of the Energy Unwrapped podcast, I speak to Glyn Hudson and Trystan Lea from OpenEnergyMonitor. We go back to the early days of OpenEnergyMonitor, from Glyn and Trystan meeting as childhood friends, to building early energy monitoring hardware, hand-soldered circuit boards, open-source software and the arrival of the Raspberry Pi. We also talk about how OpenEnergyMonitor moved from electricity monitoring into heat pump monitoring, how HeatPumpMonitor.org came about, and the role of John Cantor in helping shape real-world heat pump monitoring. This is a brilliant conversation about open-source energy monitoring, heat pump performance, billing-grade MID monitoring, manufacturer onboard data, installer learning, community forums, Raspberry Pi, Home Assistant, solar, batteries, EV charging and what better energy data can teach us. My own OpenEnergyMonitor journey started in October 2018 with an emonPi to monitor my solar. Since then, my setup has expanded to monitor solar, batteries, EV charging, cooking and my Vaillant heat pump. My heat pump was just system number 9 on HeatPumpMonitor.org. We also discuss what HeatPumpMonitor.org has revealed about good heat pump design, low flow temperatures, weather compensation, commissioning, accurate heat loss, simple system design, MID approved heat meters, onboard manufacturer monitoring, performance guarantees, consumer protection and what comes next for OpenEnergyMonitor. If you are thinking about getting a heat pump, take a look at my Trusted Heat Pump Installer Directory.
