What is a heat battery

The low-carbon solution that works with the home - without the complexity

Decarbonisation shouldn’t require a total property overhaul. The ZEB is engineered to solve the technical bottlenecks that often stall electrification projects, providing a high-performance alternative where heat pumps face physical or practical barriers while avoiding the high running costs common with other electric options.

A Natural Entry Point:

Transition into low-carbon heating using your existing expertise in wet systems and high-temperature performance.

Simplified Solution for Site Constraints:

Stop the frustration of turning away urban projects in flats or terraces; the ZEB is entirely internal, requiring no outdoor units, groundworks, or planning permission.

Preserve the Existing System:

Deliver the flow temperatures that customers are used to, connecting directly to existing radiators and pipework to avoid the disruption of a full system redesign.

High-performance heat. Without the property overhaul

Boiler logic:

Deliver the flow temperatures that customers are used to, connecting directly to existing radiators and pipework to avoid the disruption of a full system redesign. With a 15kW peak heat output and flow temperatures up to 80°C, the ZEB mimics the performance of a traditional heat-only boiler.

Low cost, stored heat:

The ZEB features an innovative core that stores up to 40kWh of heat to be used on demand. It automatically charges when electricity is cheapest and greenest, decoupling energy consumption from heat delivery to avoid the high running costs common with other electric options.

Simple swap. Zero stress:

A straightforward, internal replacement typically installed in just 1–2 days. Because it requires no outdoor units, connects directly to existing radiators and pipework, you eliminate planning headaches and can complete more low-carbon projects with less on-site labour.

Zero external complications:

Eliminate the risk of failed surveys caused by limited external space, noise concerns, or planning restrictions. Because the ZEB is entirely internal, it’s ideal for properties with no outdoor space, such as flats and terraces, where traditional low-carbon retrofits are often ruled out.
