Thermal energy storage firm Sunamp has been awarded over £396,000 from SP Energy Networks’ Green Economy Fund to deliver micro-district heating networks.

The company will provide five of the micro-district heating networks, which will produce low carbon heating for over 50 Edinburgh residents.

This system aims to save over 75% on carbon emissions compared to gas boilers, while providing the opportunity to recover heat from buildings with large occupancy and high passive heat gains in order to transfer it to the Edinburgh properties requiring heat.

“Sunamp is passionate about making buildings more energy efficient, sustainable and self-sufficient, whilst also reducing carbon emissions and SP Energy Networks’ funding has supported us in transforming how we heat and cool our buildings going forward,” Andrew Bissell, Sunamp chief executive, said.

In September, Sunamp received a £6 million convertible loan note investment from the Scottish National Investment Bank to increase its sales in the UK, scale up production – with the company currently having a UK manufacturing facility on the outskirts of Edinburgh and plans to open its first overseas manufacturing facility under licence in Korea in October – and to accelerate its international expansion.
