Renewable Heating Hub Homeowners' Q&A
Why Are So Many Heat Pumps Failing Homeowners?
Are poor heat pump installations being blamed on the technology when the real failure begins at the design desk?
In this episode of the award-winning Homeowners’ Q&A podcast, Mars is joined by heating engineer and design consultant Rob Berridge for a blunt examination of what thousands of homeowner complaints reveal about Britain’s heat pump rollout.
They explore why some homes remain cold after installation, why high electricity bills can often be traced back to weak hydronic design and why room-by-room heat-loss calculations are only the beginning of a competent system design.
Rob explains the importance of system water volume, emitter sizing, flow rates, index circuits and low-temperature operation – and argues that too many installations rely on buffer tanks as a substitute for proper engineering.

92. George Clarke on Heat Pumps and the New Homes We Should Be Building
01:01:05||Ep. 92Are Britain’s new homes really fit for the future? I'm joined by George Clarke, TV architect, and Ben Laverty from Mitsubishi Electric to explore new towns, new builds, low-carbon homes and why the British public deserves better from the housing industry.“I personally feel like we’ve let the public down,” says George, in a conversation that challenges how we design, build and plan our homes, while recognising the economic pressures, planning difficulties and skills shortages that make meaningful change so challenging. From the positioning of houses and windows to insulation, heat pumps, solar panels and ventilation, we discuss why better housing needs a thoughtful approach from the very beginning, with comfort, affordability and environmental performance considered together.Expect strong opinions, practical insights and plenty of laughs as we explore what it would take for Britain to build better.Please support Renewable Heating Hub by exploring our books, courses and audio guides:📕 Britain’s Heat Pump Shitshow https://renewableheatinghub.co.uk/britains-heat-pump-shitshow/📘 The Ultimate Guide to Heat Pumps https://renewableheatinghub.co.uk/go/ultimate-guide📗 From Zero to Heat Pump Hero — completely rewritten and updated for 2027 https://amzn.to/4f47f4C🛠️ Bodge Buster — completely rewritten and updated for 2027 https://amzn.to/3YPIcep📙 Heat Pumps Explained https://link.amazon/B0g9cmDYa🎓 Heat Pump Fundamentals course https://learn.renewableheatinghub.co.uk/fundamentals.htmlUse code INTRO50 at checkout to receive 50% off the Heat Pump Fundamentals course this summer.Join the Renewable Heating Hub forums for independent homeowner advice, technical discussions and real-world heat pump experiences: https://renewableheatinghub.co.uk/forumsIf you would like to sponsor an episode, please email editor@renewableheatinghub.co.uk.🌿 FOLLOW RENEWABLE HEATING HUB 🌿Website: https://renewableheatinghub.co.ukForums: https://renewableheatinghub.co.uk/forumsYouTube: https://www.youtube.com/c/renewableheatinghubInstagram: https://instagram.com/renewableheatinghubEmail: editor@renewableheatinghub.co.ukGot a question or experience to share?

89. UK vs USA: Who Has Made the Bigger Heat Pump Mess?
47:58||Ep. 89Heat pumps work. So why do so many installations fail? Mars is joined by JT Stewart from Slipstream for a revealing transatlantic investigation into heat pumps in Britain and the United States. Although the two countries use the technology very differently, homeowners on both sides of the Atlantic are being hit by familiar problems: oversized systems, poor design, inadequate training and sales processes that can put profit before performance. Britain has largely embraced air-to-water heat pumps. America is dominated by air-to-air and ducted systems. But does either country genuinely install them well? Mars also examines how these failures compare with the problems uncovered in his book, Britain’s Heat Pump Shitshow.

84. Did Your Installer Actually Commission Your Heat Pump Properly?
27:04||Ep. 84Most homeowners spend weeks researching which heat pump to buy. But what if the machine itself isn’t the biggest factor determining comfort, efficiency and running costs?In this episode of the award-winning Homeowners’ Q&A Podcast, we're joined by Liam Knowles from The Heating People to investigate one of the most overlooked stages of a heat pump installation: commissioning.We explore what proper commissioning should actually involve, why so many heat pumps are left running at fixed flow temperatures, how weather compensation should be configured and why simply getting the radiators hot is not proof that a heating system has been commissioned correctly.This video is sponsored by Stiebel Eltron: https://renewableheatinghub.co.uk/go/stiebel-eltronStiebel Eltron free webinars: https://www.stiebel-eltron.co.uk/en/service/showsandevents/hpnextshowsandevents.htmlPlease support us by getting a copy of The Ultimate Guide to Heat Pumps.
