Decarbonising heat with heat batteries

Introduction

Clare Brown is joined by Iain Duncan, Business Development Director at Tepeo, to discuss the role heat batteries can play in decarbonising housing stock at scale. The conversation introduces heat battery technology in a clear, accessible way, outlining how it works and why it is gaining attention as a low-carbon heating option for retrofit programmes. With a focus on the realities faced by housing providers, the episode explores where heat batteries may offer advantages over heat pumps, particularly across dense, space-constrained, or electrically limited homes.

The discussion then turns to the practical considerations of deploying heat batteries across existing housing portfolios. Clare and Iain examine installation challenges, resident impact, system flexibility and integration with the electricity grid, alongside the policy and funding landscape influencing uptake. Drawing on real-world retrofit experience, the episode provides housing associations, local authorities and asset managers with valuable insights to support decision-making as they plan and deliver scalable, resident-focused solutions for decarbonising heat.
