Replace gas boilers with renewables for domestic hot water – transition to net zero by 2035
Sunamp thermal batteries are a low carbon, reliable, space-saving alternative to traditional hot water cylinders.
You’ll cut carbon emissions and reduce maintenance costs across your housing stock.
Ideal for large-scale retrofit or new-build projects where space is at a premium.
Space-saving: up to x4 smaller than hot water cylinder being replaced
There’s often limited space inside homes which rules out installing bulky hot-water systems (and the associated pipework) when looking to use heat pumps instead of gas boilers.
The solution is an integrated system with a Sunamp thermal battery fitting neatly in a cupboard and being charged by renewable energy from an air-source or ground-source heat pump.
Energy efficiency improves by storing heat generated when electricity is cheaper and releasing it when it is needed. Residents enjoy hot water on demand while using less energy.

Instead of having the old boiler in the kitchen, you’ve got this new technology in the cupboard. It’s unobtrusive and it works. And that’s the bottom line.

Lower maintenance costs
Thermal batteries require no regulatory annual maintenance – unlike domestic gas boilers and unvented cylinders – and greatly simplify installation. Our batteries come with a market-leading 10-year warranty on the heating element.
No legionella testing is needed since each battery holds less than 5 litres of water.
What’s more, the batteries’ compact size releases storage space in each home which helps you meet mandatory space standards.
Low and zero carbon technology in use
Tackle fuel poverty
The HeatShare project shows how elderly residents use less energy for hot water with thermal batteries in their homes as part of five micro-scale district heating networks.
Hot water on demand
Residents of the EastHeat project like that Sunamp batteries give them hot water at mains pressure on demand. They also like that the slimline batteries free up cupboard space.
Retrofit to decarbonise
Here, the thermal battery and heat pump combination cut CO2 emissions by an estimated 420 tonnes per year – or nearly 70% – by enabling gas supplies to be removed from 364 homes.
