The challenge with integrating renewables

To meet the UK government’s net zero, integrating renewables into new projects & retrofits is the need of the hour. Heat pumps, solar PV and low-carbon heat networks all require additional thermal storage for hot water.

Traditional hot water cylinders are bulky and take up valuable space, which makes integrating or retrofitting renewables into space-constrained properties challenging.

How the space-saving Thermino design addresses this challenge?

Up to 4x smaller than an equivalent hot water cylinder, Thermino heat batteries can be installed in spaces where traditional cylinders cannot. Thanks to our Optimino technology, this allows integrating renewables into projects where they otherwise wouldn’t fit.

The Thermino heat batteries are modular; their sleek look & cuboid shape unlocks more design freedom for you, and more floor & storage space for residents.

Energy efficient and reliable

Our heat batteries are lined with vacuum insulation panel, which is 19 times more performant than polystyrene foam. This translates to ultra-low heat losses—up to 2-4x lower than a cylinder—and more energy savings.

Thermino heat batteries use world-leading Plentigrade phase change material, which has proven to have zero degradation over 40,000 cycles of charging & discharging (equivalent to 55 years of daily use). This ensures the heat batteries remain exceptionally reliable, safe and fully recyclable, boosting your project’s economic viability and resilience.

Capture and reuse industrial waste heat with Central Bank Mini

Central Bank Mini gives specifiers a compact way to capture, store and reuse heat from industrial and commercial processes. Waste heat, or heat from boilers and heat pumps, can be stored for later use in process heating, CIP and washdown, space heating and pre-heating.

Each unit stores up to 80 kWh of thermal energy and can be connected in series or parallel to match the capacity and power required. At up to three times smaller than an equivalent hot water thermal store, it can also significantly reduce the space needed for thermal storage.

Case studies


Social housing

Heat pumps and heat batteries replaced old storage heaters in three social housing tower blocks in Thurrock, helping residents save money. It is estimated that the project will cut their energy bills by 67% and lead to a 70% reduction in carbon emissions

New build housing

Sunamp heat batteries play a significant role in contributing to the Whetstone Green Apartments’ sustainability goals: they are estimated to save about 7.651 tCO2e in-use emissions in the first year and 269.763 tCO2e over 25 years compared to a regular gas combi boiler

Historic church conversion

To create a heat network, six boreholes were drilled vertically under the ground surrounding the church to form two shared ground arrays. Each apartment and townhouse was fitted with a ground source heat pump connected to one of these arrays, and a Sunamp Thermino heat battery to provide hot water.

Turning industrial waste heat into profit

At a Japanese soap factory, Central Bank Mini captures surplus boiler heat and stores it for use at a neighbouring chemical plant. The project cut initial equipment costs by around 30% and achieved CO₂ payback in under a year, demonstrating how compact thermal storage can make industrial waste heat recovery commercially viable.
