Sunamp Hot Water
Sunamp Instant Hot Water
Sunamp’s heat battery systems deliver high-performance, instant hot water using advanced phase-change thermal stores designed for seamless integration into residential and commercial projects. These ERP A+ rated units offer a compact, energy-efficient, and low-carbon solution – up to four times smaller than traditional cylinders – making them ideal for space-constrained sites or property upgrades.
Sunamp thermal stores can be charged from any energy source, enabling cost control by utilising off-peak grid electricity or free energy from solar PV, heat pumps, and other renewables. Once charged, heat is delivered instantly, meeting high-demand hot water requirements at mains pressure and supporting flexible installation configurations including modular and scalable setups.
Available in sizes from 70L to 300L equivalent hot water output, these systems ensure precise specification for property size and usage profile. With a market-leading 10-year core warranty and no mandatory annual maintenance, Sunamp is designed for reliability and long-term service.
Thousands of UK installations demonstrate proven performance – Sunamp is now the standard for efficient, space-saving hot water storage that outperforms legacy cylinders in both retrofit and new build environments. Units accept all standard power sources, offer ultra-low standing heat losses, and support advanced control features for trade partner and client satisfaction.
