BetaTalk - The Renewable Energy and Low Carbon Heating Podcast Disrupting Zero Disrupt: Inside EDF's 'Express Heat Pump Initiative'
28 snips
Nov 5, 2025 Clayton (Clay) Brown, a senior figure at EDF Heat Pumps, unwraps their innovative 'Express' initiative designed to streamline heat pump installations. He discusses the initiative's consumer-first focus and how it simplifies the process through technology like Carno software for faster surveys. Clay emphasizes the importance of performance guarantees and quality standards to support installers. With costs aiming to match traditional gas boilers, the initiative seeks to boost consumer adoption and aid gas installers in transitioning to renewables.

Episode notes
Tariff And Behaviour Trump Flow Temps
- Customers care about monthly running costs and tariffs far more than technical details like flow temperature.
- System efficiency, tariff choice, and customer behaviour together determine perceived value.
Survey Software Misses Some Field Details
- An engineer using Zero Disrupt found customers asking for flow temperatures, but the software didn't provide them.
- The engineer also worried the software missed a long primary pipe run under decking which affects cost.
Cylinder Rules Finally Clarified
- Different certification bodies interpreted MCS rules inconsistently, especially around cylinders.
- EDF, NAPIT and others secured clarity enabling reuse of many existing cylinders for heat pumps.
