Sunamp Ltd.

World-leading thermal storage technologies. Visit us on www.sunamp.com Passionate creativity and innovation are what got us to our world-leading position today.

At Sunamp we design, manufacture and sell thermal batteries that store energy using our patented phase change materials and discharge it as heat that can be used for hot water, heating and cooling. Our thermal storage products help householders replace gas boilers, house builders cut carbon emissions, property developers retrofit buildings with low-carbon heating systems, industrial facilities re-

use waste heat and much more. They trust our products to increase their renewable energy use and cut out ‘burn on demand’ fossil energy. Sunamp’s vision is of a world powered by affordable and renewable energy sustained by compact thermal storage. Our mission is to transform how heat is generated, stored and used to tackle climate change and safeguard our planet for future generations. We're a fast-growing company with great opportunities for talented individuals to do their bit to combat climate change. And we reward based on merit. We’re a global company committed to net zero and headquartered in the United Kingdom.

Hot water shouldn’t cost homeowners more than it needs to.
Traditional cylinders come with ongoing costs that add up over the years.

Here's how Thermino helps you avoid these:

Thermino is designed to be G3 compliant, so there is no need for mandatory annual safety checks, cutting yearly servicing costs.

It doesn’t require energy-intensive anti-Legionella cycles, thanks to the small internal water volume, helping avoid unnecessary energy use.

Thermino heat battery has up to 4x lower heat losses compared to an old hot water cylinder, keeping stored heat for longer.
This higher energy efficiency turns more of the supplied energy into usable hot water.

The systems you specify shape more than buildings - they shape land use, resource demand and the legacy we leave behind.
Our heat batteries enable low-carbon heating in a compact, efficient form, meaning a smaller footprint, both inside the home and out in the world. Conservation by design.

When space is tight in your newbuild, conversion or retrofit project, every square inch matters.

This Sunamp Thermino 300 ePlus heat battery, installed in a former airing cupboard, replaces a traditional gravity-fed cylinder. It now delivers mains pressure hot water on demand using rooftop solar PV and a diverter - with ultra low standing heat losses.
This compact thermal storage is designed for modern low-carbon homes.
✔️ No G3 certification needed to install
✔️ No energy-intensive Legionella protection cycles required
✔️ No limescale build up
✔️ No annual servicing on the appliance - only external components need checking
✔️ Up to 4x smaller than a cylinder

Our heat batteries simplify compliance for specifiers, and support SAP performance in all-electric designs.

Thermino TS – the space-saving alternative to indirect hot water cylinders - now available for UK homes and housing developments.
The latest addition to our Thermino range of heat batteries for hot water, the Thermino TS heat battery connects to external heat sources such as boilers, offering an energy- and space-efficient replacement for traditional hot water cylinders.
It is also compatible with heat pumps, so whether you are upgrading from gas to renewables now or later, there is no need to change your thermal store.
Compact and quick to install, Thermino TS fits into tight spaces with minimal disruption, which makes it ideal for both retrofit and new build projects for specifiers and installers.
Thanks to its vacuum insulation and low-volume design, it delivers hot water efficiently, with no need for energy-intensive Legionella protection cycles. Available in three models - Thermino 150 TS, 210 TS and 300 TS - in litre-equivalent sizes for easy comparison with conventional cylinders.

3.5 vs. 48 - That’s how many heat pumps were sold per 1000 households last year in the UK compared to Norway. That's a 14x gap.
The latest figures from the European Heat Pump Association reveal what many in the industry already know: heat pump deployment across Europe is still uneven, but the potential is huge.

And while the UK has made gains in heat pump uptake, there’s one barrier that remains consistent - how to make heat pumps a viable option in every home, especially with challenges related to space, plumbing, or tenant impact come into play when moving away from combi boilers.

That’s where Thermino can make a difference. Sunamp’s compact thermal batteries make it easier to specify heat pumps even in properties where a traditional hot water cylinder simply wouldn’t fit.

As Europe heads into heat electrification and low-carbon heat, we believe compact thermal storage will be a key enabler. Let’s close that gap. Get in touch: www.sunamp.com/en-gb/contact-us-uk/

Designing for safety, decarbonisation and tenant wellbeing?

As we move away from combi boilers to meet carbon targets, hot water storage is returning to homes - especially in social housing retrofits and new builds.

That shift brings new responsibilities. Specifiers must now navigate compliance with HSE ACoP L8, G3, TM13, Future Homes Standard 2025 and PAS 2035, all while managing space constraints and minimising disruption to residents.

Traditional cylinders often mean ongoing Legionella checks, temperature monitoring and maintenance, all adding to operational and cost burden.

Thermino takes a different approach.
It stores energy, not water, eliminating stagnant water and reducing Legionella risk by design. No tanks to clean or thermal disinfection cycles. Thermino provides safe, space-saving hot water delivery that aligns with compliance frameworks.

We were front and centre at the opening of Retrofit 25 – What’s Stopping Us? - the new exhibition at Building Centre in London. The launch preview was attended by over 200 industry guests.

One of the standout features of the exhibition is the ‘house without walls’ demonstration space, where visitors can get hands-on with cutting-edge energy efficiency technologies. Our Thermino heat battery takes pride of place in the display, showcased in an under-the-stairs installation as a game-changer for helping people save space, reduce energy waste and lower carbon emissions.

This exhibition, a collaboration between Building Centre and the National Retrofit Hub (NRH), is all about tackling the big challenges in retrofitting buildings—innovation, sustainability, and financial barriers. These are key topics for us at Sunamp as we work towards better, smarter home energy solutions.

Our team members will also be speaking at Retrofit 25 panel discussions and webinars over the coming months, so stay tuned!
🗓 Running until 19 September

Hot water storage that fits beautifully into modern homes. 🏠

For and shaping contemporary spaces in modern sustainable homes, every inch of floor & cupboard space matters.
When fitting in renewables to meet emissions targets, the ancillary equipment for hot water, traditional hot water cylinder, looks bulky, outdated and inelegant in a modern home.

Sunamp’s heat batteries blend into the modern aesthetic - they are compact, efficient and suit contemporary living spaces.

But more importantly, they free up space and improve energy efficiency while delivering mains pressure hot water comfort. 🌏🚿🍃
They can be tucked under a kitchen worktop, under stairs or quietly sit in the utility cupboard, making hot water delivery inconspicuous - perfect for designing modern homes using renewables.

If you are designing sustainable buildings and want to rethink how hot water is stored, get in touch with us: www.sunamp.com/en-gb/contact-us-uk/

If you are involved in our , the ‘Retrofit 25: What’s Stopping Us?’ exhibition (https://www.buildingcentre.co.uk/whats_on/exhibitions/retrofit-25-whats-stopping-us), created in partnership with the National Retrofit Hub, is now open at Building Centre in London, launching today and on until September 19, 2025.
