Underheat

At Underheat, we’re building smarter, faster ways to decarbonise UK homes — starting with social housing. We use automation and AI to design and manufacture more efficient heating systems for heat pumps, reducing the cost and disruption of retrofit upgrades. We believe the transition to a low carbon future should benefit everyone—improving the comfort, health and happiness of those who need it most. ___________ EnergyWall Our flagship home heating product, EnergyWall, combines underfloor heating with external wall insulation, to heat and cool homes from the outside. Think underfloor heating, mounted on the outside of a home. By covering external walls with dense pipe layouts, we can transfer more heating or cooling at lower temperatures to reduce energy use and save residents money on their energy bills. By focusing on the outside of homes and manufacturing our systems as prefabricated boards, we can simplify installation and reduce the need for costly and disruptive internal works. Resident benefits: greener heating, cheaper bills, improved comfort, minimal disruption. Building owner benefits: cheaper retrofit, simple installation, extended asset longevity. System benefits: decarbonising UK homes, tackling fuel poverty, improving health, supporting grid resilience. ___________ We want to co-design this solution with social housing providers, retrofit experts and local communities so please get in touch if you want to know more.
