Swapping gas for renewables and the role of thermal storage

Answer 3 quick questions to see how Thermino thermal batteries can make your next retrofit or new build better

Start now

No one in social housing questions the need to retrofit old housing stock to meet today’s carbon reduction requirements and net zero goals.

Efficient low carbon energy solutions can also lower energy bills, cut emissions and improve residents’ comfort, safety and well being.


The real question is how?

Finding space for the hot water storage needed for renewable heating systems is just one of the challenges social landlords face.

So what are the best practice zero carbon strategies emerging for the social housing sector?


We work with low carbon energy partners and social landlords to deliver award winning renewable energy systems into hundreds of high occupancy buildings and new builds.

Our super-compact thermal storage has been developed to address the unique and disparate needs that characterise social housing in the UK today.

Watch the interview with Sunamp and Gentoo Group about the ‘Core 364’ gas replacement programme for seven tower blocks in Sunderland, UK.

Retrofit to decarbonise

High-rise apartments, Sunderland

Here at the Core 363 project, the thermal battery and heatpump combination cut CO2 emissions by and estimated 420 tonnes per year – or nearly 70% – by enablign gas supplies to be removed from 364 homes.

Tackle fuel poverty

Retirement homes, Midlothian, Scotland

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

Multi-sized homes, central Scotland

Residents of the EastHeat project like that Sunamp batteries give them hot water at mains pressure on demand. They also like that the slimeline batteries free up cupboard space


Thermino heat batteries are up to x4 smaller than the equivalent hot water cylinder.

No maintenance:

Once installed, Thermino units require no annual servicing.

Minimal disruption:

Thermino units are easy to install with minimum fuss

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.
