Send a textIn this episode of BetaTalk, Nathan welcomes back engineer and coder James Twallin to discuss the technical nuances of the UK's energy transition. While industry debates are often binary, this conversation focuses on objective data regarding gas infrastructure, the physics of high mass heritage buildings, and the importance of real world boiler monitoring for hydronic heat pump success.Key Topics Discussed:The "Invisible" Gas Leak Problem: James reveals his research into the UK's gas network. He explains how current energy policy and EPC ratings often ignore upstream methane leaks. Using Freedom of Information data, he highlights the prevalence of leaks in ancient cast iron mains featuring 19th century archaeological engineering.Decarbonising Heritage Buildings: A deep dive into a 200 year old stone church project. James explains why steady state modelling fails in these environments and how a physics based approach allowed for a successful, intermittent air to air heat pump installation by leveraging the building's thermal mass.Optimising Hydronic Transitions: Nathan and James discuss a new monitoring device designed to track existing boiler behaviour. By gathering data on flow temperatures and cycling, engineers can create a more accurate blueprint for future heat pump performance.Technical Correction During the recording, a Bosch study involving 4,000 units was discussed. While mentioned as a heat pump survey in the audio, Nathan would like to clarify that the study actually monitored 4,000 gas boilers. Thanks to the Patrons of the Guild of Master Heat Engineers who help make these podcasts possible Support the showLearn more about heat pump heating by followingNathan on Linkedin, Twitter and BlueSky

Pithy quotes "We do our job well if the homeowner forgets about us, because the system just works." "The bar is so low in some homes that doing a quality install can genuinely change someone's life." "The best way to learn is crawling in the crawl space behind a great technician and handing them tools." Semi-famous quote that fits our theme "Stay hungry, stay foolish." © Steve Jobs Shreyas Sudhakar joined the Building HVAC Science podcast to talk about his path from rocket propulsion engineering to building high-quality heat pump installs in California. Bill and Eric found him through his thoughtful LinkedIn posts, and Shreyas shared that a friend's relentless heat-pump evangelism finally pushed him to look deeper. Once he did, the tech clicked. He realized HVAC and rockets share the same core idea: moving energy through systems, and the math is not as far apart as it sounds. What really pulled him in was the homeowner experience. After talking with homeowners on Nextdoor and Reddit, and even calling contractors for quotes himself, he kept hearing the same frustrations: heat pumps feel expensive, contractor advice is inconsistent, trust is low, and myths like "heat pumps don't work in the cold" still show up, even in mild California climates. Shreyas' view is simple: most homeowners do not care what the equipment is called. They care about comfort, noise, bills, and safety, and the best outcome is when the system is so reliable they barely think about it. Shreyas now runs Vayu, a lean heat pump installation company operating with vetted subcontractor partners, while his Heat Pumped newsletter and podcast focus on education for homeowners, technicians, and policy folks. Vayu handles the end-to-end process, from load sizing and equipment selection to permits and rebates, while partner shops focus on the craft of installation. His definition of success is not just a happy install day, but a customer still loving the system a decade later, and technicians thriving because the model removes desk work and supports quality work at scale.

Send me a messageWhat if the biggest mistake in climate action is that we're still designing buildings for a climate that no longer exists?In this episode of the Climate Confident Podcast, I'm joined by David Sellers, principal architect at Hawaii Offgrid Architecture & Engineering. David designs net-zero and off-grid buildings on Maui, not as an experiment, but because the climate he's designing for is already shifting. Faster than most regulations, models, or assumptions can keep up.Buildings account for a huge share of global emissions, energy demand, and climate risk. Get the design wrong today, and we lock in higher emissions, higher costs, and lower resilience for decades. This conversation is about how to stop doing that.We dig into why designing with historical climate data is quietly undermining net zero goals, and why buildings completed today will spend most of their lives in a climate no human has experienced before. David explains how shifting wind patterns, rising temperatures, water scarcity, and fire risk are already breaking “best practice” design rules.You'll hear why off-grid no longer means uncomfortable or compromised, and how advances in solar, batteries, heat pumps, and building envelopes have changed the economics completely. We also talk about fire-resistant construction after the Lahaina fires, reusing waste surfboard foam to create ultra-insulated building blocks, and why resilience that only the wealthy can afford isn't resilience at all.This is a grounded, experience-driven look at climate tech, decarbonisation, and the energy transition, without the fantasy timelines or glossy nonsense.

If all U.S. single-family homes adopted heat pumps, it would equal taking 32 million cars off the road. But we need to 10x the current adoption pace by 2030. Quilt CEO Paul Lambert explains how his team from Google, Apple, and Nest is making heat pumps irresistible — with sleek design, 25+ SEER2 efficiency, and software that makes systems smarter over time. He also discusses Quilt's rapid scaling strategy, its $20M Series B funding round, and the new 3-zone system.

The Boston Housing Authority is piloting a new type of window-mounted heat pump that's relatively inexpensive and easy to install.

We're back! And we're talking about the value of post-occupancy evaluation (POE) with Tom Robins and Leigh Fairbrother of Switchee.Their business is POE for landlords that's intended to improve the quality of life for the residents that they rely on. Capturing sensor data, analysing it, and synthesising that into something their clients can use.Essentially, this means validating the quality of fabric, the impact of retrofit works, and anticipating car crashes—metaphorical ones.We get a really helpful explanation of Awaab's Law around 25–30 minutes in, too.

Heat pumps are having a moment. Last year, the U.S. passed China to become the world's number one market for heat pumps—and they're not slowing down. But while heat pumps are efficient and effective on paper, they haven't always been objects of desire. Until now.This week, Molly talks to Paul Lambert, CEO and co-founder of Quilt, about building a heat pump company that's equal parts climate solution and consumer product. Paul explains how his team is reimagining the mini-split heat pump—not just as an HVAC system, but as a piece of technology you're proud to have on your wall.We dive into:How heat pumps work: Why an AC is basically "a half-broken heat pump" that only runs in one directionThe two types of heat pumps: Ducted systems vs. ductless mini-splits, and why room-by-room control is a game-changerDesign as climate strategy: How Quilt spent half their initial capital on a domain name and invested heavily in industrial design to create pull, not just policy pushThe installer advantage: Why partnering with contractors (instead of doing it all in-house) unlocked national scaleSmart grid integration: How Quilt's internet-connected system enables demand response without sacrificing comfort—curtailing load in empty rooms while keeping occupied spaces perfectThe data center opportunity: How replacing electric resistance heating with heat pumps near data centers can free up 75% of the energy load—without building new generation capacityWhy incentives help but aren't required: 60% of America is primarily cooling-driven, and heat pumps are just better air conditionersPricing reality: Quilt is competitive with high-end Japanese mini-splits, not luxury-priced like early Nest thermostats or TeslasThe personal mission: How Paul's Alberta roots in the fossil fuel industry and his commitment to his kids' future drove him to climate techKey insight: Space heating and cooling represent half of all home energy use and 70% of fossil fuel consumption in homes—making HVAC the single biggest lever for decarbonizing buildings.Links:Quilt: https://quilt.comFind a Quilt installer: https://quilt.com (click "Find an Installer")All episodes: https://www.everybodyinthepool.com/Subscribe to the Everybody in the Pool newsletter: https://www.mollywood.co/Become a member for the ad-free version of the show: https://everybodyinthepool.supercast.com/ Hosted on Acast.

Send me a messageHeating cities by opening windows is not a joke. It's how many buildings still control temperature in winter, and it's a climate disaster hiding in plain sight.In this episode, I'm joined by Drew Maggio, Technical Director at Highmark Building Efficiency, to unpack why buildings are one of the biggest, most underestimated levers in the climate transition, especially in dense cities like New York.Buildings account for roughly 70% of New York City's emissions, yet much of the stock was designed for an era of cheap fossil fuels, crude controls, and worst-case thinking. Drew works at the sharp end of fixing that. We talk about what actually breaks when you try to electrify old buildings, and why bad assumptions, not bad technology, are slowing progress.You'll hear why oversizing heat pumps for rare freezing days drives up costs and kills projects. We dig into how treating heat as a resource, not waste, unlocks massive gains, from wastewater heat recovery to capturing subway heat that currently just bakes tunnels to 100º F. And you might be surprised by how much energy can be recovered before it ever leaves a building.We also get into Local Law 97, New York's landmark building emissions regulation, and why it's forcing real-world change instead of glossy pledges. This is a grounded, practical conversation about decarbonisation, climate tech, policy, and the uncomfortable reality that many “heritage” systems are simply uncontrolled systems we've tolerated for too long.

Deep Dive of Derek Cole's article: https://www.simmonsonehour.com/blog/s... Episode 678 of the Home & Life Comfort PodcastSnowstorms always bring the same heat pump worries:Is that steam normal?Why is there ice on the outdoor unit?Why does it feel like it's blowing cool air?And what does “Aux Heat” actually mean?In this deep dive, I break down what's normal winter heat pump behavior… and what are true warning signs that you need to call a professional.Most heat pumps will frost up during freezing weather and then clear themselves off with a defrost cycle. That can look dramatic — steam, longer run times, even Aux Heat turning on — but it's often completely normal.But there is a line between normal winter operation and a real mechanical problem.In this video, we cover:Why heat pumps ice up after snow and sleetWhat the defrost cycle is (and why steam is usually NOT smoke)Why your system may run nonstop during extreme coldWhat Aux Heat means — and when it's expectedWhen NOT to switch to Emergency HeatThe real warning signs: solid ice encasement, fan failure, falling indoor tempsIf your heat pump is acting up after the storm, this video will help you know when to relax… and when to pick up the phone.

Send us a textPrimary Expert: Mick Wall (IT Specialist, University of Sheffield & Founder of Energy Stats UK)Host: Nathan Gambling (Beta Talk Podcast and Betateach Newsletter)Core Topics: Heat Loss Accuracy, Weather Compensation vs. Room Influence, Smart Tariffs (Octopus Energy).Executive Summary (TL;DR)Standard MCS heat loss calculations often overestimate ventilation losses in older homes by up to 300%. Expert consumer Mick Wall demonstrates that real-world air changes in a 1930s semi-detached house are closer to 0.5 ACH (Air Changes per Hour) rather than the CIBSE default of 1.5–3.0 ACH. This episode explores how to verify heat loss using Pulse Tests and CO2 Decay to prevent heat pump oversizing.1. Challenging MCS Heat Loss DefaultsStandard industry calculations often rely on static building guides that fail to account for the actual "tightness" of 20th-century builds.The Problem: Default values from CIBSE and MCS result in oversized heat pumps, leading to short-cycling and reduced efficiency. The Evidence: Mick Wall utilises three distinct methodologies to validate air change rates: Pressure Testing: Utilising the Build Test Solutions Pulse kit for rapid air evacuation measurement. CO2 Decay Monitoring: Deploying Purrmetrix sensors to track gas dissipation over 7 days. Reverse Modeling: Matching 4 years of Open Energy Monitor data against Spruce fabric loss models. 2. Comfort Dynamics: Weather Compensation vs. Room InfluenceWhile "pure" weather compensation (adjusting flow temperature based on outdoor air) is better than on/off control, it often lacks the "aggression" needed for rapid recovery.Pure Weather Comp: Best for steady-state efficiency but may fail during sudden internal temperature drops. Room Influence: Wall advocates for this approach and currently uses his Vaillant control with Havenwise which is an optimiser. Key Takeaway: Insulation (e.g., bay window upgrades) provides "unmeasurable comfort" by eliminating drafts, even when the fabric watt-saving is minimal. 3. Optimising the "Elephant in the Room": Smart TariffsA high-quality heat pump installation must perform efficiently regardless of the tariff. However, leveraging the Octopus Energy Kraken platform provides significant cost advantages.Agile vs. Cozy Tariffs: Understanding how to shift loads without sacrificing comfort. The Risk: Relying on cheap overnight electricity to "mask" a poorly designed, low-efficiency system. Support the showLearn more about heat pump heating by followingNathan on Linkedin, Twitter and BlueSky

Heat pumps sit at the heart of Europe's strategy to cut emissions and reduce dependence on imported gas. Under the EU's REPowerEU plan, the bloc is targeting 60 million heat pumps by 2030. By the end of 2025, almost 30 million units were already installed — progress, but still only halfway to the goal.Gerard and Laurent are joined by Paul Kenny, Director General of the European Heat Pump Association (EHPA), to unpack why adoption has surged in countries such as Japan, Scandinavia and parts of the US, while many European markets continue to lag.After a strong year in 2022, European heat pump sales slowed in 2023 and 2024 amid high upfront costs, a shortage of qualified installers, weaker policy support and an unfavourable price relationship between gas and electricity. Paul explains why confidence is returning in 2025, with 1m heat pumps sold across 13 European countries in the first half of 2025, a 9% increase on 2024.We also look beyond residential heating to the rapid rise of industrial heat pumps, which could become a major decarbonisation tool for sectors requiring heat below 200°C, including food processing and pharmaceuticals. The conversation explores how heat pumps can add flexibility to the power system, in some cases reducing the need for battery storage, and why data centre heat management is emerging as a key new application.As the leading voice of Europe's heat pump industry, EHPA is working to make heat pumps the preferred technology for sustainable heating and cooling — strengthening Europe's competitiveness, resilience and energy security in the process.-----At Redefining Energy, we are excited to be part of International Energy Week, where some of the biggest names in global energy come together for a packed agenda tackling the ideas, technologies, and policies shaping the future.

In this short podcast, Bryan answers a listener-submitted question and explains why heat pumps get a bit weird: when it comes to superheat in heat mode. He also explains how we can move heat from outdoors to indoors, even in temperatures below freezing (cold temperatures just have less heat, not zero heat). In order to move heat in very cold conditions, we need very low suction pressures and cold coils, which gives us a high compression ratio. Superheat will be affected by these conditions. Remember: superheat that is too low can cause floodback, and superheat that is too high can cause the compressor to overheat. Superheat is easy to check in cooling mode, but it's harder in heating mode, especially since the suction line is at the outdoor unit. In heating mode, we can only measure superheat between the coil outlet and the reversing valve inlet, which is a very short run of tubing. The superheat will also be less stable in heat mode in cold weather, and it will have a wider range of "normal" values than cooling mode, depending on the conditions. Superheat could even drop to zero with some fixed-orifice metering devices (which would cause floodback). That's why many of these heat pumps have accumulators, which collect liquid refrigerant to protect the compressor. Even though TXVs attempt to maintain superheat, you may still see some variation in heat mode during cold weather. EEVs are common in ductless systems and are highly controllable but maintain relatively low superheats by design; fast metering control, intelligent logic, accumulators, and low refrigerant charges allow them to avoid floodback in low temperatures. In any case, spikes and drops in temperature can cause the superheat to jump or collapse because the load changes (as the outdoor coil is the evaporator). Frost buildup on the coil also inhibits airflow and heat transfer, causing the superheat to change as the evaporator pressure and temperature drop. Defrost also introduces chaos to the equation. All of these should influence your judgment when checking superheat to diagnose or commission a system in heat mode.   Have a question that you want us to answer on the podcast?

Send me a messageIndustrial heat powers half of manufacturing - and almost no one is talking about it.What if one of the biggest supply chain emissions problems has been hiding in the boiler room all along?In this episode, I'm joined by Addison Stark, CEO and co-founder of AtmosZero, to tackle one of the most overlooked risks in industrial sustainability: steam. A 160-year-old technology that still delivers roughly half of all industrial heat, quietly underpinning food, chemicals, pharmaceuticals, brewing, and more.We explore why industrial heat is routinely labelled “hard to abate” and why that label may be more habit than reality. You'll hear how electrified, drop-in steam boilers can replace combustion without forcing factories to redesign their operations, and why productised solutions matter more than bespoke decarbonisation projects if we want scale.We break down why heat pumps can outperform resistive electric boilers by a factor of two, how ignoring waste heat can actually accelerate deployment, and why engineers and plant managers, not press releases, ultimately decide what technologies make it into supply chains. You might be surprised to learn how Europe's energy volatility and policy certainty are reshaping the economics of industrial heat, and why steam decarbonisation could follow a very different curve from solar or EVs.This is a conversation about resilience, risk, and the unglamorous infrastructure that keeps global supply chains moving. Hidden systems. Real impact. No hype.

Send me a messageMost people never think about industrial heat. Yet half of all manufacturing emissions come from it. My guest this week, Addison Stark, CEO and co-founder of AtmosZero, is on a mission to electrify one of the dirtiest, most overlooked pieces of infrastructure on Earth: the steam boiler.In this episode, Addison and I uncover how a technology unchanged since the 1860s can finally go clean. We talk about the hidden carbon footprint of steam, why “waste heat recovery” can actually slow progress, and how heat-pump boilers can cut industrial energy use in half while delivering zero-emission steam. You'll hear how his team's first installation at a Colorado brewery is already brewing beer with carbon-free heat, proof that decarbonisation doesn't have to mean disruption.We also explore the bigger picture: how electrified heat could transform everything from food and pharma to chemicals and cosmetics, why Europe's gas crisis is accelerating the shift, and what policy tweaks could make clean steam the default everywhere.If you've ever wondered how to decarbonise the “hard-to-abate” sectors, this is the episode you've been waiting for.

QUOTES from the Episode "Instead of landlines everywhere, give every heat pump a cell phone and let it call home." "We're seeing close to 40% of heat pumps undercharged or leaking—no wonder callbacks are high." "What gets measured gets managed." — often attributed to Peter Drucker (fitting this data-driven shift)   Brendan Hermalyn (CEO/founder, Thalo Labs) traces a zig-zag path from NASA and defense to self-driving cars—then into HVAC. His through-line: high-reliability sensing and prognostics. Thalo's product aims to "give every heat pump a cell phone," using a small, non-invasive module that snaps inside VRFs/splits (and eventually larger plants), measures power and line temps, backhauls via cellular, and flags undercharge/leaks and power-quality issues before they become emergency calls. It's equipment management, not a full BMS—lightweight to install, built for techs, and friendly to API integrations, texts, and weekly roll-ups. Brendan argues the market is ready: most commercial buildings still lack BMS, Wi-Fi is fragile for critical telemetry, and the economics of sensors/cloud have flipped. Thalo avoids tapping the refrigerant loop, prioritizes fast installs (often 10–30 minutes), QR/location tagging, and even a "buzz this unit" feature to find the right rooftop box. Early field data is sobering—he's seeing ~40% of heat pumps undercharged and/or leaking—driving callbacks, compressor failures, and energy waste. The pitch to contractors: turn break-fix chaos into planned maintenance, white-label the savings report, and train new techs faster with data-driven cues. Oh, and the name? "Thalo" like the deep sky blue—an homage to adding tech to make the picture clearer.   Brendan's LinkedIn: https://www.linkedin.com/in/brendan-hermalyn/ Thalo Labs: https://thalolabs.com/   This episode was recorded in October 2025.  

In this episode of the HVAC Know It All Podcast, host Gary McCreadie talks with Jim Fultz, National Technical Training Manager at Copeland and a former Emerson trainer. Jim explains the concepts of thermal and economic balance points in heat pump systems, breaking down how each affects system performance and efficiency. He walks through how to calculate these balance points using real examples, showing when a heat pump needs backup heat. Jim also discusses how the Sensi Touch 2 thermostat helps manage these settings by letting users program exact switch-over points. His advice gives techs the tools to improve system setup and avoid costly service calls. In this episode, Jim Fultz explains the difference between thermal and economical balance points in heat pump systems. He shows how thermal balance is about the heat pump's ability to meet a home's heating load as outdoor temperatures drop, while economical balance relates to energy cost and efficiency. Jim uses real examples to show how to calculate these points and why getting them right matters. He also talks about using tools like the Sensi Touch 2 thermostat to set and control balance points. His tips help contractors design better systems and avoid performance issues during cold weather. Expect to Learn: What thermal and economic balance points mean in heat pump systems. How to calculate a balance point using load and capacity data. Knowing the thermal balance point helps avoid cold-weather failures. How the Sensi Touch 2 thermostat helps control backup heat use. Why balance point planning improves system performance and customer comfort.

Data centers are creating a grid crunch, so what if they paid to solve it by upgrading our homes? I chat with Rewiring America's Ari Matusiak and PG&E's Carla Peterman about a new report proposing that hyperscalers fund household electrification to free up the grid capacity they desperately need. We explore how this reframes households as crucial energy infrastructure and creates a win-win-win for tech companies, utilities, and everyday people. This is a public episode.
