Fuel price volatility creates uncertainty — but it also creates opportunity. The Heat Bank transforms low-cost electricity and surplus heat into high-temperature thermal energy, replacing oil, gas, or inefficient electric heating with a smarter, market-driven approach. By charging when power prices are lowest and delivering heat when demand rises, it stabilises costs, lowers emissions, and strengthens operational resilience — making decarbonisation a competitive advantage.
Whether you’re replacing oil or gas boilers, reducing the cost of direct electric heating, or looking to decarbonise your operations, the Heat Bank gives you a smarter way to produce heat. By storing thermal energy in gravel at temperatures up to 400 °C, it delivers reliable hot air or hot water for both industrial processes and building heating. You charge when electricity prices are lowest, discharge when demand rises, and reduce your exposure to fuel volatility — all while lowering emissions and stabilising your heating costs.
Charge when prices are low and shifting heat production to the most cost-effective hours.
Get dependable heat when you need it, regardless of fuel market volatility or electricity price spikes.
Eliminate oil and gas usage to reduce emissions while controlling when heat is generated.
Easy integration with your existing boilers, ovens, production and thermal systems
Recuperate surplus process heat curing cooling cycles and store it for later use.
Reduce exposure to peak electricity costs by producing heat during off-peak hours.
With the Heat Bank, you’re not just adding thermal storage — you’re adding intelligent control. The same Smart Controller that powers our battery and seasonal storage systems automatically optimises when you charge and discharge heat, based on real-time pricing, weather data, and your demand profile.
The Heat Bank is built as an integrated thermal storage system, combining high-temperature gravel storage, resistive heating elements, insulation, and hydraulic connections within a compact structure. Designed for both process and building heat applications, it delivers stable thermal output while remaining adaptable to different site requirements. The modular architecture simplifies installation and ensures long-term operational reliability.
At its core, the Heat Bank uses a simple and robust storage medium: gravel. The system can be deployed as a single module or scaled modularly to meet higher capacity requirements. Stored heat can be delivered as hot air or hot water for industrial processes or building heating, and surplus hot air from existing processes can be used as an additional charging source. Controlled electrical resistive heating and advanced insulation enable high-temperature operation up to 400 °C, ensuring stable and reliable performance in demanding environments.
