Sunamp thermal storage systems can help decarbonize leisure and hospitality projects while maintaining the high standards of comfort which customers expect.
Our space-saving heat batteries store and deliver heat with optimal efficiency and ultra-low heat losses, suitable for hotels and residential settings, sports facilities and a range of other hospitality businesses.
How compact thermal storage can benefit leisure and hospitality projects
Consistent hot water, even at peak times
Thermino heat batteries store energy when it’s readily available, whether from renewable sources or off-peak grid electricity, and release this as mains-pressure hot water when required. In leisure and hospitality settings, this means a steady supply of instantaneous hot water for the comfort of your customers, without creating spikes in energy demand.
Compact and efficient systems
Sunamp heat batteries are up to four times smaller than the equivalent hot water cylinder or traditional thermal storage system they replace, thanks to our patented energy-dense Plentigrade® phase change material. This makes the systems ideal for space-constrained plant rooms or freeing up storage space in residential facilities.
Low maintenance, long lifespan
The high-performance phase change material inside our heat batteries has been tested to the equivalent of 50 years daily use with minimal degradation, making this a reliable solution for your commercial projects. The systems are simple to install and don’t require mandatory annual inspections or servicing – only standard maintenance is required on the auxiliary plumbing components.
Meet net zero goals
Boost your sustainability credentials by integrating Sunamp thermal storage systems with heat pumps and solar PV, making it easy to move from gas to low-carbon heat. Thanks to the high-performance insulation inside our heat batteries, you’ll also benefit from low heat losses which can help lower primary energy use.

Holiday lodges set to save £7,200 a year thanks to Thermino and heat pumps
Forest Holidays chose Thermino heat batteries and air source heat pumps to provide heating, hot water, and heat the hot tubs in 12 new luxury lodges at their Strathyre site. In addition to the significant financial savings, the system gives peace of mind for staff as they can fill the hot tubs and still guarantee hot water supply to the cabins when guests arrive.
