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.

Send me a messageWhat if upgrading your home to be climate-friendly was as simple as scanning it with your phone?In this week's episode of the Climate Confident Podcast, I talk with Grant Gunnison, founder and CEO of Zero Homes - a former NASA and MIT engineer who's now tackling one of climate tech's toughest challenges: decarbonising existing homes. His company uses smartphone scans and digital twins to design fully-scoped, permit-ready electrification plans - no site visit, no clipboard, no chaos.You'll hear how Grant's team is cutting out the “truck rolls” that make home upgrades expensive and slow, saving homeowners money while helping contractors stay profitable. We dig into why electrifying 60 million U.S. homes is both an engineering nightmare and a golden opportunity, and how technology, not policy alone, can finally make it scale.We also unpack the human side: what really motivates homeowners to switch to heat pumps, why induction cooking is a secret health win, and how removing the awkwardness of having strangers poke around your home can actually accelerate climate action.

Simply operating America's buildings uses more than a third of the country's energy. A major chunk of that is temperature control — keeping the indoors cool in the summer and warm in the winter. Heating eats into families' budgets and burns a tremendous amount of fuel oil and natural gas. But what if we could heat and cool buildings more efficiently, cleanly, and cheaply? On this week's episode of Shift Key, Rob and Jesse talk to Dulcie Madden, the founder and CEO of Dig Energy, a New Hampshire-based startup that is trying to lower the cost of digging geothermal wells scaled to serve a single structure. Dig makes small rigs that can drill boreholes for ground source heat pumps — a technology that uses the bedrock's ambient temperature to heat and cool homes and businesses while requiring unbelievably low amounts of energy. Once groundsource wells get built, they consume far less energy than gas furnaces, air conditioners, or even air-dependent heat pumps. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is an adviser to Dig Energy.Mentioned:Dig EnergyTechCrunch: “Geothermal is too expensive, but Dig Energy's impossibly small drill rig might fix that”Princeton University's Geo-Exchange SystemJesse's downshift; Rob's downshift. --This episode of Shift Key is sponsored by …Hydrostor is building the future of energy with Advanced Compressed Air Energy Storage.

Every autumn pigs are released into the New Forest - the tradition of Pannage. The pigs gobble up the acorns from the thousands of oak trees in the Forest. Anna Hill hears why it's particularly important this year, to protect ponies and cattle from a bumper crop of potentially toxic acorns. The pigs suffer no ill effects from indulging. The New Forest's Head Agister explains the logistics of releasing the pigs and getting them home again.A new report commissioned by the research body Rural England claims the Government policy on rolling out environmentally friendly home heating is 'heat pumps or nothing'. The report says heat pumps can be expensive and impractical to install in old rural housing, in part due to the insulation needed to make the pumps warm rooms efficiently. It suggests that more should be done to promote alternative renewable fuels, which could be used in existing heating systems.And we're ringside at the Cockermouth Mule Gimmer Lamb Sale to reflect on livestock markets' role as a social hub.Presenter: Anna Hill Producer: Sarah Swadling

PLMA Awards Webinar: CPUC + Energy Solutions on the TECH Clean California Heat Pump Water Heater (HPWH) ProgramA 2025 PLMA Award of Excellence Winner, TECH Clean California, launched by the California Public Utilities Commission (CPUC), promotes clean heating technologies through incentives for heat pump water heater (HPWH) installations. The program has funded over 15,000 installations resulting in significant greenhouse gas savings. As of October 2023, new mandates required that HPWH customers also enroll in demand response programs. To enable this, the team provided additional education to contractors which has led to high enrollment rates. In December 2024, the contractors were asked to provide “proof of enrollment” for their installations which has continued to enhance program participation and contractor engagement. Today, the HPWH contractors are  evolving into demand response leaders in their own right.

Is there a collaboration problem in retrofit within the social housing sector? That was the premise for this conversation with Rafe Bertram, an architect and retrofit expert—appearing in a personal capacity—who was very surprised when I posed the question because he's found collaboration to be a strength in the sector, at least in London.In the end it led to a conversation about what he's learned from the experiences he's had working on retrofits in the social housing sector, in his community, and even doing big flashy Apple stores.The most interesting bit though is the strategy he's using to reduce the cost of retrofit, with his theory of reactive planning. It's an approach that takes a systematic integrated asset management approach and adds strategic opportunism into the mix in a way that enables him to piggyback essential works, like roof replacement, and use them as a catalyst for getting into a building to do the sustainability stuff that's usually a lower priority.Notes from the showRafe Bertram on LinkedinRetrofit Kentish Town The Good Homes Alliance websiteRafe's finance report for the Good Homes Alliance — “The Green Shift – The existing financial incentives for higher environmental performance of new homes” (October 2023) More links to articles about green building, favourable finance, and better valuations:Homebuyers pay a ‘green premium' of up to £40,000 for the most energy efficient properties (September 2021)—Lloyds Banking GroupHalifax includes EPC ratings in maximum lending calculationsHalifax to use EPC rating in affordability calculationsOctopus reducing interest rates for finance capital: 4 criteria = 1.25% discount, 6+ criteria = 2.00% discount**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

Kiwis have racked up more than a billion dollars in green loans for energy efficient items like EVs, solar panels, and heat pumps. BNZ, ASB, and ANZ all lend up to $80 thousand on a 1% interest rate over three years. Massey University Banking Expert Claire Matthews says these are small loans, meaning the banks are pumping them out, while not actually lending a huge amount. She told Mike Hosking customers still have to go through the same process as loans with higher interest rates, and go through affordability checks.

  The Green Impact Report Quick take: 16-year heat pump water heater evangelist Gregg Holladay reveals how homeowners can slash energy costs by $400+ annually, why May 2029 changes everything for 50% of American homes, and his "proactive replacement" strategy that turns water heater failures into profitable opportunities. Meet Your Fellow Sustainability Champion Gregg Holladay is Business Development Manager for Specialty Markets at Bradford White, where he champions heat pump water heater technology across residential and commercial markets. The industry's only 16-year veteran of heat pump water heaters, Gregg introduced America's first Energy Star-rated unit while at GE in 2009. A sustainability pioneer who built his first energy-efficient home 33 years ago on a Kentucky farm, he's known for translating complex technology into compelling financial stories—like how homeowners can save $400+ annually while achieving 420% efficiency. Gregg teaches contractors nationwide that water heaters are evolving from "failure replacement" to proactive upgrades that actually pay for themselves.

Messing with water heaters sounds like something that professionals who typically deal with hard wiring and electrical work would much rather avoid. However, in today's increasingly connected home, where every system appears to interact and communicate with one another, water heaters are becoming smarter. Here, we chat with Cala Systems Co-Founder and CEO Michael Rigney about the company's forthcoming smart heat pump water heater, how it's changing the game from an efficiency standpoint, and the role he hopes custom integrators can play in getting their product into more consumers' homes, quickly. https://youtu.be/QiPSVg9i3gw

This episode is all about case study in circularity and a group of people turning waste into useful materials for the built environment. Daniel Dinizo and Charmaine Cu-Unjieng of NaturLoop are bringing a new bio-based product to market that transforms waste coconut husk into a material that's something between MDF and a particle board.For us, this presented a chance to talk about how sustainable materials are developed, the challenges of bringing them to market and how responsible businesses can approach supply chain development (the big challenge now). As professionals who work with LCAs, EPDs, and carbon calcs all the time it was refreshing to get into a product that will have an impact that can be accounted for in human terms, as well as the usual economic and environmental terms. They're also fundraising right now, so here's the pitch from Charmaine.NaturLoop at the Final Stage of Pre-Seed Funding"NaturLoop, the Swiss–Philippine climate-tech startup behind Cocoboard, is at the final stage of its pre-seed round. Cocoboard is the first industry-ready fibreboard made entirely from coconut husk waste and natural adhesives—a truly biocircular material. Featured at Interzum Cologne 2025, Cocoboard embodies the shift in construction and furniture toward biocircularity—no longer a trend but the future of materials. Europe's sustainable furniture market is set to more than double to $42.6 bn by 2032, with consumers paying around 10% more for sustainable products. NaturLoop is closing its round soon, inviting strategic investors to co-build a climate-positive business that reduces deforestation and uplifts poor coconut farmers—making the industry more future-proof."Notes from the showCharmaine Cu-Unjieng on LinkedinDaniel Dinizo on Linkedin NaturLoop on Linkedin The NaturLoop websiteA short film about Cocoboard®An investor CTA from CharmaineAn example of Cocoboard in use as a speaker box for a Schwab System**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

Heat pumps are the EVs of HVAC—so why aren't we all using them?Stephen Lake, a highly successful engineer turned climate-tech entrepreneur, is here to explain why heating and cooling is the most overlooked piece of the decarbonization puzzle.After selling his last company to Google, Stephen founded Jetson to tackle one of the biggest—and slowest-moving—sectors of home energy: HVAC. From cold-weather performance to noise, he busts the myths about heat pumps and outlines why they haven't hit mass adoption in North America.Spoiler: it's not the tech. It's everything else—price, friction, contractors, complexity.Expect a crash course in sector disruption, including Jetson's decision to build everything in-house and cut install costs by half through full-stack operations. If Tesla built HVAC, it'd look like this.

In this episode we are exploring the relationship between financial institutions and the built environment in relation to sustainability, building performance and mitigating climate change with Ian Bhullar and Ronnell Reffell from UK Finance, the UK financial sector's membership organisation.The episode itself was prompted by a report that UK Finance published in relation to the incoming UK Government's own Warm Homes Plan: Greening Homes, Creating Growth: Unlocking demand for green home finance. Its recommendations will be familiar to anyone who has been working in the green building sector but it's notable because these arguments and demands are being presented by the banks and lenders.For us this presented an opportunity to find out what the finance sector is actually thinking about how to address the demands of the built environment in relation to climate change and the financial risk that comes with it. Most importantly, they're serious about the matter—this is not ESG-style fluff, they know they need to draw in expertise from built environment professional and they want to know what people like you think.Notes from the showIan Bhullar on LinkedinRonnell Reffell on Linkedin The UK Finance website The report itself—Greening Homes, Creating Growth: Unlocking demand for green home finance**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

In this episode of the HVAC Know It All Podcast, host Gary McCreadie is joined by Jamie Kitchen, an HVAC expert, Training and Account Manager at Danfoss, to talk all about TX valves for heat pumps. Jamie breaks down how these valves work in both heating and cooling modes and why they need to handle refrigerant flow in two directions. They discuss the parts of a TX valve, how pressure and temperature control the flow, and why Danfoss uses stainless steel in their design. Jamie also explains how proper installation helps prevent common issues and why external equalizers are important in many setups. It's a must-listen for anyone working with heat pumps. Jamie Kitchen from Danfoss joins Gary to talk about TX valves used in heat pumps. Jamie explains how these valves control refrigerant flow when switching between heating and cooling. He breaks down how the valve parts work together, using pressure and temperature to open and close. They also talk about why heat pumps need special valves, and how check valves help flow in both directions. Jamie explains why Danfoss uses stainless steel bulbs and tubes to stop leaks and handle rough conditions. It's a helpful talk for techs who want to understand heat pump valves better and install them correctly. Jamie explains how TX valves in heat pumps work like traffic lights for refrigerants, letting it flow the right way in heating or cooling. He shows how the valve uses pressure from a sensing bulb, a spring, and the coil to open or close. Jamie and Gary talk about why using an external equalizer helps the valve work better, and how check valves let refrigerants move both ways. Jamie also shares why Danfoss uses stainless steel parts; they last longer and don't break or leak. It's a smart guide for techs who want to understand these valves and avoid system issues. Expect to Learn: How TX valves work in both heating and cooling modes. Why heat pumps need valves that flow in both directions. How pressure and temperature control valve opening and closing.

In this insightful episode, Bill and Eric are joined by Abhi Katamneni from Efficiency Canada and Nate Adams, also known as the House Whisperer, for a wide-ranging conversation on the future of home performance, policy, and how HVAC contractors can play a central role in the electrification and decarbonization of housing. Abhi shares lessons from his ride-alongs with contractors across North America, emphasizing how real-world experience shapes policy that actually works. Nate dives into his shift toward consumer education and the systemic problems he's observed in program design and incentives. Together, they unpack how well-meaning policies can backfire when they disrupt the natural rhythm of contracting businesses—highlighting the urgent need for smarter, more contractor-centric approaches. They discuss “boundary spanners,” the unintended consequences of top-down mandates, and why the HVAC service truck is ground zero for climate solutions. Both guests call for immersion, experimentation, and communities of practice to move from boutique success stories to scalable change. Some quotes from the Episode: “The brain can't absorb what your butt can't endure.” – Abhi “If you're not building something shovel-ready for contractors, what are you even doing?” – Abhi “A heat pump isn't just green—it's better.

In this episode of the HVAC Know It All Podcast, host Gary McCreadie talks with Drew Tozer, an energy advisor and Partner at Foundry Heat Pumps, and Expert Advisor at Building Decarbonization Alliance and Jouleia, about heat pump systems and how to make homes more comfortable. They discuss common problems like hot and cold rooms, the myths around heat pumps, and why right-sizing equipment matters. Drew explains how heat pumps have improved and how to pick the best one based on home size, ductwork, and local climate. They also cover hybrid setups, electric backups, and simple tips to avoid overworking systems and keep indoor air comfy and efficient. Drew Tozer explains how many homes have rooms that are too hot or too cold because of wrong HVAC sizing. He shares why heat pumps are a smart fix when sized right and how older myths make people avoid them. Drew says most homes don't need gas backup and that hybrid systems help when ductwork or power panels are limited. Gary shares job stories showing how right sizing and good planning improve comfort. They both agree that knowing a home's needs and choosing the right system can lower costs, save energy, and keep homes more comfortable year-round. Here, Drew explains how many HVAC systems are too big for the home, which causes hot and cold spots and short run times. Like using the right shoe size, right-sizing heat pumps helps keep comfort steady. He says heat pumps now work well even in cold places, and hybrid setups help when ductwork or power is limited. Gary shares how proper installs and load checks made big comfort changes. They remind techs that smaller, well-planned systems run better, save energy, and avoid problems like noise, bad airflow, and early breakdowns.
