Cheshire firm helps RBS slash heating bill

An energy saving additive applied to central heating units at three Royal Bank of Scotland (RBS) branches in a year-long trial has cut gas usage by nearly a third. 

The water-based EndoTherm additive was developed by Endo Enterprises in Warrington.

The technology works by changing the surface tension of fluid in central heating systems, which increases thermal contact and heat transfer. This means less fuel is ultimately consumed to maintain a set temperature.

RBS agreed to run a trial of the technology at three of its branches in May 2016 as part of the Innovation Gateway, a matchmaking alliance that gives small businesses the chance to partner with major organisations looking to reduce the costs and environmental impacts of their buildings. 

‘Effective product’

In one year, EndoTherm reduced gas consumption at the three sites by 29 per cent, saving more than 10 tonnes of CO2 in the process.

Based on the pilot, the payback period for the installation has been calculated at less than year, with the product lasting for seven years.

Jo Saunders, innovation programme manager at RBS, said: “EndoTherm is a simple-to-use but effective product; the team were extremely professional and provided regular updates throughout the trial.

“Endo Enterprises were always there to support and provide regular updates on the performance of their products, and could not have done enough to ensure we had a successful pilot; we look forward to working with them further in the future.”

Matchmaking success

The success has led to more interest from other Innovation Gateway partners, including Heathrow Airport.

“It’s a major challenge for small businesses to get in front of large corporations and prove how our products can not only help them achieve savings but also drive business sustainability goals”, said Ben Sallon, managing director at Endo Enterprises.

“Without the Innovation Gateway platform, it would have been far more difficult to connect with companies like RBS.”
