A new type of equipment is being trialed at Edinburgh University to sustainably power homes and offices in Edinburgh, Scotland.
This innovation has been developed by SeaWarm, a University of Edinburgh Spin-Off Company that harnesses the power of water sources from seas, rivers, ponds, and even mine water to provide efficient heating and cooling for homes and businesses.
Known as the Water Source Heat Pump (WSHP), the system utilizes thermal energy stored in these water bodies.
SeaWarm’s HotTwist tech extracts heat from water
The system features a heat exchanger, such as SeaWarm’s HotTwist technology, which is designed to extract heat from the water. The heat exchanger collects thermal energy from the water and transfers it to the heat pump, where it is compressed to a higher temperature suitable for heating purposes.
This system is optimized for stable water temperatures, ensuring consistent performance, and can even operate efficiently in extreme conditions by utilizing the latent heat of ice fusion, according to the company.
As per The Guardian, SeaWarm’s heat pump is currently being tested by Edinburgh University in an affordable housing project near the Firth of Forth, close to the Forth Bridge, at a gold-mining museum in southwest Scotland, and in a commercial greenhouse in Fife.
The report also mentioned that another heat pump system is planned for installation this summer at the Scottish Seabird Centre in North Berwick, which will also harness energy from the Firth of Forth.
