Anzen has secured £1.1 million in pre-seed funding to revolutionize home heating technology. This clean tech startup is developing a groundbreaking solid-state heat pump that promises to make sustainable heating accessible to all homes. The funding marks a significant milestone in Anzen’s journey to transform how we heat our homes while addressing climate challenges.
The story of Anzen began with real-world problems faced by its founders. CTO Preethi Jayakumar’s personal battle with mould due to poor ventilation in her home sparked the initial idea. Similarly, CEO Dhruv Shah was motivated after witnessing his aunt’s struggles with inadequate heating, which significantly impacted her health and comfort during winter months.
These personal experiences highlighted a critical gap in the current heating market. Most existing solutions primarily cater to the “able-to-pay” segment, leaving behind homes in fuel poverty or those with special circumstances like small flats and older buildings. This realization led Dhruv Shah and Preethi Jayakumar to create Anzen with a mission to make clean heating technology accessible to everyone.
The innovative approach by Anzen addresses this market gap through their unique hardware solution. The Anzen hardware consists of a plug-and-play, solid-state, refrigerant-free heat pump that can be installed in under a day. This CE-certified technology offers a safe, low-carbon alternative to traditional heating methods that have dominated the market for decades.
What makes Anzen technologies stand out is their focus on accessibility and efficiency. Unlike conventional systems that require extensive modifications to homes, Anzen’s solution is designed to work with existing infrastructure. This makes the transition to clean energy heating possible for properties that were previously considered too difficult or expensive to convert.
The development of Anzen engineering solutions was guided by a clear understanding of consumer needs. Their heat pump technology not only reduces carbon emissions but also helps lower energy bills – a crucial benefit for households struggling with rising energy costs. This dual approach of environmental and economic benefits has attracted significant attention from investors.
The £1.1 million pre-seed funding came from notable investors including Desai Ventures, Green Angel Ventures, Carbon13, Sustainable Ventures, Colbridge Ventures, and One Planet Capital. This investment will support Anzen in deploying pilot installations and scaling up manufacturing capabilities to meet growing demand.
Technical advisor Michael Reid has provided valuable guidance, while Nishul Saperia and Iain Campbell have offered crucial commercial support to help Anzen navigate the complex energy market. This combination of technical expertise and business acumen has positioned Anzen for success in a competitive industry.
Looking ahead, Anzen aims to decarbonise a million homes by 2035. This ambitious goal reflects their commitment to making net-zero homes the new normal across the UK and beyond. As Anzen continues to develop and refine their technology, they remain focused on their core mission of combining planetary and people-centric decarbonisation.
The journey of Anzen demonstrates how personal experiences can inspire innovative solutions to global challenges. By addressing both environmental concerns and social inequalities in home heating, Anzen is not just creating a product – they’re pioneering a more inclusive approach to sustainability. With their solid-state heat pump technology, Anzen is helping to ensure that the transition to clean energy leaves no home behind.
