Anzen is developing solid-state heat pump technology designed to overcome the barriers that prevent many UK homes – especially hard-to-decarbonise ones like flats – from switching to low carbon heating. Their compact, wall-integrated Climate Wall system provides heating, cooling, ventilation, and air purification in one unit, without the need for an outdoor unit or complex installation.

With a high-efficiency thermoelectric design, the system can modulate from 0.2kW to 2kW, making it adaptable to both draughty and well-insulated homes. Installation takes just a few hours and can be done by a local electrician, making it a scalable retrofit option that doesn’t compromise on comfort or indoor air quality.

Anzen is on a mission to decarbonise one million UK homes by 2035, offering a people-focused, practical route to net zero that puts affordability and ease of use at its core.

It was fantastic to see Anzen’s innovative Climate Wall solution presented at Futurebuild – a compact, solid-state heat pump that could play a vital role in retrofitting the UK’s hardest-to-decarbonise homes. Their approach tackles some of the most pressing barriers in the heat pump market – cost, complexity, and space – with a practical, scalable alternative. We’re excited to see how Anzen’s pilot projects progress and how their technology evolves to support a just, affordable energy transition across the housing sector.
